Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described:
It please refers to shown in Fig. 1-Fig. 4, retarder 1 includes the worm screw 3 for having the shell 2 of axis hole and being mounted in shell 2
With worm gear 4, a kind of gap of worm adjustment mechanism disclosed by the invention is mounted on 2 side of shell of retarder 1.
Adjustment mechanism includes bearing block 5, and the sliding of bearing block 5 is set in axis hole, and as shown in figures 5-9, bearing block 5 includes connection
Section 6 and thread segment 7, linkage section 6 are fixedly connected by bearing with worm screw 3, and thread segment 7 is located at one of bearing block 5 far from worm screw 3
End.Bearing block 5 further includes gripping section 8, and gripping section 8 is located at the side of thread segment 7, and the end face of gripping section 8 is provided with convenient for turning
The holding tank 9 of dynamic bearing seat 5.Holding tank 9 is equipped with several and is symmetrically distributed on the end face of bearing block 5.The axis of the present embodiment
Seat 5 is held equipped with 4 holding tanks 9, the adjacent holding tank 9 of every two forms 90 degree of angle.It is adjusted using the bearing of commercial type
Cutter is placed in holding tank 9, rotating shaft holder 5, and bearing block 5 drives worm screw 3 to move along axial, to make worm gear 4 and snail
Bar 3 is engaged connection with the smallest grinding tooth in gap.
It after adjusting, needs to lock bearing block 5, prevent because the gap of screw thread leads to worm screw 3 on bearing block 5
It is moved axially in transmission process.Therefore it is equipped in the outside of the thread segment 7 of bearing block 5 for preventing worm screw 3 from axially moving
Dynamic locking plate 10, as shown in figs. 10-11, locking plate 10 are cyclic annular and are threadedly coupled with bearing block 5, the annular end of locking plate 10
