Abstract
With a mechanical transmission axle for Novel stop block, the utility model relates to the technical field of transmission shaft structure.The utility model is to overcome existing automotive transmission when numbers of gear steps increases, and axle numbers of steps also needs to increase, and owing to there is diameter difference between each shaft part, will the diameter of shaft end be caused to reduce, and finally affects the problem of transmission reliability.Its positioning ball to be assembled in annular groove in end upper semi-circle groove and to expose half, first semicircle C shape block and the second semicircle C shape block to be all embedded in annular groove and to make the inner headed face upper semi-circle groove of the first semicircle C shape block be buckled on positioning ball, and shield ring sleeve is connected on the periphery of the first semicircle C shape block and the second semicircle C shape block composition.The utility model, compared with the axle in conventional speed changer, by increasing semicircle C shape block and back-up ring, can realize the axially locating effect of the part such as bearing, gear, does not need to reduce the diameter of axle simultaneously, ensures the reliability of speed changer.
Description
Technical field
The utility model relates to the technical field of transmission shaft structure.
Background technique
Many employing step axis structures in automotive transmission transmission shaft conventional at present, the location of bearing relies between centers diameter difference.When numbers of gear steps increases, axle numbers of steps also needs to increase, and owing to there is diameter difference between each shaft part, by causing the diameter of shaft end to reduce, finally affects transmission reliability.
Summary of the invention
The purpose of this utility model is to provide a kind of mechanical transmission axle with Novel stop block, the utility model is to overcome existing automotive transmission when numbers of gear steps increases, axle numbers of steps also needs to increase, owing to there is diameter difference between each shaft part, to the diameter of shaft end be caused to reduce, finally affect the problem of transmission reliability.A kind of mechanical transmission axle with Novel stop block of the present utility model, it is made up of axle 1, first semicircle C shape block 2, second semicircle C shape block 3, back-up ring 4, positioning ball 5;
Axle 1 need location place one ring groove 1-1 is set, be provided with the semicircle groove 1-2 for assembling and positioning steel ball 5 in annular groove 1-1 the end, the inner headed face of the first semicircle C shape block 2 is provided with the semicircle groove 2-1 for assembling and positioning steel ball 5, positioning ball 5 to be assembled in annular groove 1-1 in end upper semi-circle groove 1-2 and to expose half, the width of annular groove 1-1 is equal with the second semicircle C shape block 3 thickness with the thickness of the first semicircle C shape block 2, first semicircle C shape block 2 and the second semicircle C shape block 3 to be all embedded in annular groove 1-1 and to make the inner headed face upper semi-circle groove 2-1 of the first semicircle C shape block 2 be buckled on positioning ball 5, back-up ring 4 is socketed on the periphery of the first semicircle C shape block 2 and the second semicircle C shape block 3 composition.
The utility model, compared with the axle in conventional speed changer, by increasing semicircle C shape block and back-up ring, can realize the axially locating effect of the part such as bearing, gear, does not need to reduce the diameter of axle simultaneously, ensures the reliability of speed changer.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Embodiment
Embodiment one: composition graphs 1 illustrates present embodiment, present embodiment is made up of axle 1, first semicircle C shape block 2, second semicircle C shape block 3, back-up ring 4, positioning ball 5;
Axle 1 need location place one ring groove 1-1 is set, be provided with the semicircle groove 1-2 for assembling and positioning steel ball 5 in annular groove 1-1 the end, the inner headed face of the first semicircle C shape block 2 is provided with the semicircle groove 2-1 for assembling and positioning steel ball 5, positioning ball 5 to be assembled in annular groove 1-1 in end upper semi-circle groove 1-2 and to expose half, the width of annular groove 1-1 is equal with the second semicircle C shape block 3 thickness with the thickness of the first semicircle C shape block 2, first semicircle C shape block 2 and the second semicircle C shape block 3 to be all embedded in annular groove 1-1 and to make the inner headed face upper semi-circle groove 2-1 of the first semicircle C shape block 2 be buckled on positioning ball 5, back-up ring 4 is socketed on the periphery of the first semicircle C shape block 2 and the second semicircle C shape block 3 composition.
Working principle:
In annular groove in assembly process on axle, 2 semicircle C shape blocks and 1 back-up ring being installed, when not reducing the diameter of axle, the axially locating effect of bearing, gear part can being realized.
