Description
Technical field
The utility model belongs to auto parts machinery field, is specifically related to a kind of universal joint assembly, particularly the reinforced universal joint assembly of one.
Background technique
In car transmissions and other system thereof, in order to realize the transmission of power between rotating shaft that some axes intersect or relative position often change, universal driving device must be adopted, universal joint is again indispensable parts in universal driving device, have in reality and apply very widely, general universal joint in use, certainly exists certain frictional force between needle roller and axle sleeve, cause the shortening in working life, therefore for the reinforcement of universal joint assembly and consolidation process just necessary.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the reinforced universal joint assembly providing a kind of good seal, frictional force little.
The purpose of this utility model is achieved in that a kind of reinforced universal joint assembly, it comprises cross axis body, the cross direction of described cross axis body is provided with the spindle nose integrated with cross axis body, described spindle nose is provided with axle sleeve, described axle sleeve side end face inwall is provided with end face inner groovy, described axle sleeve side end face outer wall is provided with the outer groove of end face, described axle sleeve is rolled with between spindle nose be connected by equally distributed needle roller, pad groove is provided with between described axle sleeve and needle roller, described needle roller left end is provided with slide block, described axle sleeve opening and spindle nose joint are provided with oil sealing, described slide block is arranged on the position between oil sealing and needle roller.
Described end face inner groovy shape is identical with spindle nose end shape.
Described needle roller is cylindrical.
The inner surface accuracy of described pad groove is 1.6, and described pad groove is that high speed steel is made.
The side that described slide block is connected with spindle nose is provided with the arcuate structure matched with spindle nose.
Described slide block is that high speed steel is made, and described slide block is through smooth treatment.
The beneficial effects of the utility model: the utility model adopts pad groove to be arranged between needle roller and axle sleeve, the internal surface simultaneously padding groove reaches surface accuracy 1.6 after processing, so just greatly reduce the frictional force between needle roller and spindle nose, effectively prevent the wearing and tearing of sleeve lining simultaneously, the side that slide block is connected with spindle nose is provided with the arcuate structure matched with spindle nose, the smooth treatment of shoe surface can reduce the friction between needle roller and oil sealing further, pad groove and slide block are that high speed steel is made, mechanical strength can be increased, total the utility model has compact structure, mechanical strength is high, good airproof performance, the advantage that frictional force is little.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, cross axis body 2, spindle nose 3, axle sleeve 4, end face inner groovy 5, the outer groove 6 of end face, needle roller 7, pad groove 8, slide block 9, oil sealing.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment 1
As shown in Figure 1, a kind of reinforced universal joint assembly, it comprises cross axis body 1, the cross direction of described cross axis body 1 is provided with the spindle nose 2 integrated with cross axis body 1, described spindle nose 2 is provided with axle sleeve 3, described axle sleeve 3 side end face inwall is provided with end face inner groovy 4, described axle sleeve 3 side end face outer wall is provided with the outer groove 5 of end face, described axle sleeve 3 is rolled with between spindle nose 2 be connected by equally distributed needle roller 6, be provided with between described axle sleeve 3 and needle roller 6 and pad groove 7, described needle roller 6 left end is provided with slide block 8, described axle sleeve 3 opening and spindle nose 2 joint are provided with oil sealing 9, described slide block 8 is arranged on the position between oil sealing 9 and needle roller 6.
The utility model is in use: be placed in axle sleeve by the spindle nose in cross axis body cross direction, subsequently needle roller is placed slide block in the outer part, subsequently oil sealing is placed on axle sleeve opening to seal, such universal joint is in the process used, because pad groove decreases the frictional force between needle roller and axle sleeve, slide block decreases the frictional force between needle roller and oil sealing, so not only structure is compacter, use more smooth, total the utility model has compact structure, mechanical strength is high, good airproof performance, frictional force are little advantage simultaneously.
Embodiment 2
As shown in Figure 1, a kind of reinforced universal joint assembly, it comprises cross axis body 1, the cross direction of described cross axis body 1 is provided with the spindle nose 2 integrated with cross axis body 1, described spindle nose 2 is provided with axle sleeve 3, described axle sleeve 3 side end face inwall is provided with end face inner groovy 4, described axle sleeve 3 side end face outer wall is provided with the outer groove 5 of end face, described axle sleeve 3 is rolled with between spindle nose 2 be connected by equally distributed needle roller 6, be provided with between described axle sleeve 3 and needle roller 6 and pad groove 7, described needle roller 6 left end is provided with slide block 8, described axle sleeve 3 opening and spindle nose 2 joint are provided with oil sealing 9, described slide block 8 is arranged on the position between oil sealing 9 and needle roller 6.
Described end face inner groovy 4 shape is identical with spindle nose 2 end shape.
Described needle roller 6 is cylindrical.
The inner surface accuracy of described pad groove 7 is 1.6, and described pad groove 7 is made for high speed steel.
The side that described slide block 8 is connected with spindle nose 2 is provided with the arcuate structure matched with spindle nose 2.
Described slide block 8 is made for high speed steel, and described cunning 8 pieces is through smooth treatment.
The utility model is in use: be placed in axle sleeve by the spindle nose in cross axis body cross direction, subsequently needle roller is placed slide block in the outer part, subsequently oil sealing is placed on axle sleeve opening to seal, such universal joint is in the process used, because pad rooved face precision is higher, pad groove decreases the frictional force between needle roller and axle sleeve, the smooth treatment of shoe surface simultaneously, slide block is made to decrease frictional force between needle roller and oil sealing, pad groove and slide block are high speed steel and make, intensity is very high, so not only structure is compacter, use more smooth simultaneously, the end face inner groovy shape on spindle nose top is identical with spindle nose top, decrease the friction between spindle nose and axle sleeve, total the utility model has compact structure, mechanical strength is high, good airproof performance, the advantage that frictional force is little.
