Preferably, the side of the handwheel seat is equipped with locking screw pit, locking screw pit and the locking spiral shell through handwheel seat
Nail composition screw thread pair, backing-up screw compress the end cap.
Preferably, the elastic compression part is spring.
Compared with prior art, the beneficial effects of the invention are as follows：Spring is compressed by end cap, spring is to preceding angular contact bearing
The damping action produced with the lateral forces of rear angular contact bearings is in polished rod, so as to reach the mesh for preventing that handwheel group from turning round
, the present invention solves the common fault of traditional polish rod transmission handwheel convolution, and simple in structure, good reliability, versatile, this hair
It is bright directly to be transformed in the equipment of traditional polish rod transmission, it is cost-effective.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention；
Fig. 2 is the structure enlargement diagram at A of the present invention.
In figure：1 handwheel seat, 11 limited steps, angular contact bearing before 2,3 spacing rings, 31 first holding screws, 4 springs, 5
Preceding angular contact bearing, 6 end caps, 61 backing-up screws, 7 polished rods, 8 handwheels, 81 second holding screws, 9 handles.
Embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment, belongs to the scope of protection of the invention.
- 2 are please referred to Fig.1, the present invention provides a kind of technical solution：A kind of transmission handwheel group of anti-convolution, including handwheel seat
1st, handwheel 8, handle 9 and polished rod 7, handle 9 are fixedly mounted on handwheel 8, and polished rod 7 passes through handwheel seat 1, one end of polished rod 7 and hand
Wheel 8 is fixedly connected, and the other end of polished rod 7 is connected by shaft coupling with motor, and 1 inner ring of handwheel seat is equipped with limited step 11, from limit
Position step 11 be arranged with successively on polished rod 7 toward 8 direction of handwheel before angular contact bearing 2, spacing ring 3, elastic compression part and after
Limited step 11 is close in angular contact bearing 5, the side of the preceding angular contact bearing 2, and opposite side is close to spacing ring 3, spacing ring 3 and light
Bar 7 is fixedly connected, and to prevent polished rod 7 from sliding back and forth, side of the rear angular contact bearings 5 away from elastic compression part, which is equipped with, to be used to compress
