Description
Technical field
The utility model relates to a kind of worm screw assembly.
Background technique
Worm drive is two driven off by shaft a kind of modes of spatial intersecting, have advantages of that velocity ratio is large, stable drive, but in its transmission process, worm tooth-surface is easily out of shape, and accumulates over a long period and can cause noise large, larger defects such as mechanical loss in transmission process, affect service behaviour and working life.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of worm screw assembly, stable to reach transmission, reduces the object of noise.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of worm screw assembly, comprise worm screw axis body, spindle nose position locks with the first screw 1 and spring washer 2, and axle journal position is provided with worm set 4, described worm set 4 outer race are provided with 0 shape circle 5, and axis body is successively by back-up ring 8, hexagon nut 6 and described worm set 4 lockings; Axle tail has keyway 13, and the axis body of described keyway 13 upper ends is provided with thread bush 10, and described thread bush 10 inside are provided with seal ring 12, and described seal ring 12 is made by elastomeric material.
Further, described the first screw 1 specification is M8 * 35, and described spring washer 2 specifications are M8.
Further, spindle nose one side is also provided with torque sensing device 15, and locks with the second screw 3.
Further, the axis body between described back-up ring 8, described hexagon nut 6 is provided with clutch shaft bearing 7, and described clutch shaft bearing 7 is deep groove ball bearing.
Further, on the axis body on described thread bush 10 tops, be also provided with the second bearing 9.
By technique scheme, a kind of worm screw assembly that the utility model provides, processing technology is simple, and ensuring smooth transmission is stable, and noise is little, in addition can be big or small according to sensing device induction torque, and be converted into electrical signal, for adjustment of rotational speed is made corresponding foundation.
