Furthermore, a savings in overall length of the assembly with less strain and bearing load can be effected by mounting the pinion shaft on both sides of the driving teeth with a main bearing for the shaft proper in the end wall of the case and a second bearing for a terminal pinion stub in a stiffening wall of the case centrally disposed between a pair of gears on an intermediate shaft. Objects of this invention are to provide a double reduction in which a cross shaft is employed and carries a pinion meshing with the main differential gearand is connected by means of suitable gearing with a horizontally extending drive shaft, and to arrange the axes of the drive shaft, the cross shaft and the main axle in the same horizontal plane. The combination as'iset forth in claim Wisconsin. If desired, it may be, provided with a dralnplug 6 at its lowest point. These gears are held in place by means of nuts 19, one of which may be a lock nut, and by means of a collar 19 integral with the shaft 12. To all whom t may concern. This is normally achieved by a pinion and crown wheel gear set.
I told John my idea and how we could improve drive efficiency and save costs by using a bunch of standard bicycle sprockets instead of a very expensive custom made main sprocket. By reason of the straddle mounting of the drive pinion 28, driving strains on the parts are reduced and a shorter main bearing can be employed for the drive shaft 35. As is apparent trom lthe detailed description, this construction facilitates assembly in a marked degree. Our company will offer you the best quality products with reasonable price,quick delivery,and professional after-sale service. If journalism is your burning interest, please learn all the math and science you can while you are in school. This contributes further to compactness and results from the fact that hypoid gears have non-intersecting axes.
Ain't true and I never claimed I did. It has mounted thereon between the collar 36 and an end shoulder, the inner race of an annular double row ball bearing 37 whose outer race is secured in the end wall 31 of the case by a detachable cover 38 which also mounts the usual shaft wiper seal assembly. This low speed pinion is connected to the second reduction gear which is mounted on the propeller shaft which is the output. Accordingly and to simplify the specification only the detail structure of the rear driving axle will be elaborated upon. Our 100+ year history of experience in providing the most robust solution for your axle needs is well known throughout the military and commercial industries. A second gland 2S is screwed into the gland 2l, and the two glands are provided with a tapered walled annular recess tor the reception oi packing 2S to prevent the.
A drive axle in a truck or military vehicle or a rear wheel drive car provides the final gear reduction from the propellor shaft before transferring the power into the road wheels. Taper Roller Bearings are in the form of:standard designs, open variants matched in pairs. The lower portion of the casing j is provided with a filling fitting 5 see as shown in Figure 2 ,Figure 2 by which; means oil may be readily inserted into the casing of the mechan1sm. Application led October 4, 1924. Inner support of axle shafts is the same for both types, that is, closely fitted into mating splines of the differential side gears which in turn are supported by the differential carrier. M Engine type in-line,4-stroke,water-cooled Bore x Stroke 102mmx120mm Displacement 6 cylinders , 5.
Google has not performed a legal analysis and makes no representation as to the accuracy of the date listed. The intermediate shaft is mounted at opposite ends in the two side walls of the case and passes through an axially aligned opening in the central wall or web. Projecting in the opposite direction from the drive pinion is the pinion shaft proper indicated by the numeral 35, which is to be coupled by a splined collar 36 with the universally jointed propeller drive shaft. Engine horsepower and torque information for non-Deere engines are provided by the engine manufacturer for comparison purposes only. With special reference to the drive gearing the design of the front axle can be similar or substantially like that of the rear axle with most of the parts interchangeable and all easily accessible for inspection and replacement. To slow down such a bike you carefully retard your pedalling speed.
Where is your factory location, and can we visit it9 Chengli group is located in Suizhou city, Hubei province, China. Q: How about your product After-sales service system9 A:Our main export country have accepted after-sales service,some of country used the third department service. Operations requiring increased low gear pulling ability, either single or tandem drive axles, frequently require greater ratios than is practical for single reduction axles. This is called a Portal axle. A further feature of this straight line assembly is the' ease with which all of the parts are maintained in an adequately oiled condition. For light operation on hard pavement a single small engine driving one set of road wheels ordinarily is considered sufficient but for operation on soft ground requiring more power it is deemed best to provide two power plants and transmit the drive to all wheels. These highlg' desirable results are attained without resorting to diiiicult assemblies or ditlicult mechanism but by providing an extremely simple assembly' and co-relating the parts to provide a straight line arrangement of driving elements as clearly brought out in Figure 2.
This method only has one over all ratio though, between the input and the output. After insertion of the intermediate shaft the annular roller bearing 45 is fitted to the end of the shaft and to the opening in the side wall and is held in place by a detachable cover plate 46. With these years' research and development, Rockrich has established stable cooperation with famous auto companies like dongfeng,sitom,etc. These projectingr arms or pms 41 are received in regularly positioned recesses formed in the opposed portions ot the shell like members 33, thus bracing the outer ends ot' the pins in a rigid and substantial manner. A rear axle is designated ad Hypoid or Spiral Bevel according to the type of gearing used.
Double reduction axle products are most popular in South Asia, Africa, and Domestic Market. A wide variety of double reduction axle options are available to you, There are 429 double reduction axle suppliers, mainly located in Asia. In the development of a vehicle of this type a special effort has been made to incorporate sturdy units of proven design wherever possible so that many parts can be employed which are either already available or can be manufactured quickly with existing equipment. Double reduction rear axle products are most popular in Africa, South America, and Southeast Asia. A bevel pinion 20 the drive shaft 16, as mayV be seen from Figures 1 and 2, and meshes with the gear 18 on the cross shaft. M Engine type in-line,4-stroke,water-cooled Bore x Stroke 102mmx120mm Displacement 4 cylinders,3. Spiral Bevel axles have the drive pinion on center with the ring gear.
We are a group company with one years quality guarantee. Depending on the number of teeth on the pinion and the crown wheel, revolutions can be typically reduced from 3 to 7 times. Double reduction gearing mechanism is used in huge machinery and automotives where in the speed has to be reduced at a required level. The crown wheel can be smaller, because a deep reduction isn't required, and ground clearance is improved. These bikes have only one speed and do not have a freewheel - which means you cannot coast. Thus is illustrated in Figure 3 a left spiral hypoid tooth formation as embodied in the front axle and a right spiral hypoid tooth formation in the rear axle inasmuch as rotation of both propeller shafts for forward vehicle travel is counterclockwise.
Between the side wall 24 and the central wall 29 of the case the space containing the hypoid ring gear 27 is accessible from the top of the case through an opening normally closed by the removable cover plate 44. In a drive axle assembly, an axle housing enclosing the axle shafts and differential, a gear case detachably secured to the axle housing and supporting the differential and driving gears, an intermediate shaft supported at opposite ends in the case side walls, a hypoid ring gear mounted on said intermediate shaft, a hypoid driving pinion meshing with the ring gear on an axis non-parallel to and non-intersecting that of the intermediate shaft, pinion supporting shaft portions projecting oppositely from the ends of the hypoid pinion, a bearing support for one of said shaft portions in the end wall of the case and a bearing support for the other end shaft portion located within the case between the driving pinion and the said intermediate shaft. This invention relates to motor vehicles and especially heavy duty land vehicles with multiple drive axles. However in case of double reduction mechanism, the reduction of speed takes place in 2 steps. It makes for a more efficient use of the cyclist's power. Accordingly as seen in Figure 2 the axis of the hypoid ring gear is vertically offset above the horizontal plane containing the axes of the differential and drive pinion while in the rear axle the axis of the hypoid ring gear is below this plane. It assists in locating the bearing axially and enables access to the fastening nut 43 which holds the inner bearing race on the end of the shaft.
