Description
Technical Field
The utility model relates to a speed reducer especially relates to a construction elevator standard festival jacking stabilising arrangement.
Background
When the speed reducer in the prior art is used in a special field, the adaptability and the use performance of the speed reducer cannot be fully exerted, meanwhile, the assembly precision is relatively low, the existing requirements cannot be met, and the effect in use is relatively insufficient.
SUMMERY OF THE UTILITY MODEL
The utility model discloses solve exist among the prior art not enough, provide a compact structure, the adaptation performance is outstanding moreover, can obtain the jacking stabilising arrangement of best performance's construction elevator standard festival simultaneously.
The above technical problem of the present invention can be solved by the following technical solutions:
the utility model provides a construction elevator standard festival jacking stabilising arrangement, the power distribution box comprises a box body, the box in be equipped with worm and lead screw, worm and lead screw be interval formula vertical distribution, the one end of worm extend to the box is outer, the one end of lead screw extend to the box is outer, the lead screw overcoat be meshing driven worm wheel with the worm, the both ends of worm wheel and box between fix a position through deep groove ball bearing respectively, the both ends of worm wheel and box between fix a position through thrust ball bearing respectively, thrust ball bearing be located deep groove ball bearing's outer end, thrust ball bearing be interval formula distribution with deep groove ball bearing, the both ends of worm and box between fix a position through tapered roller bearing respectively.
Preferably, two ends of the worm wheel extend outwards along the screw rod respectively, two ends of the worm wheel and the box body are sealed through oil seals, and the oil seals are located at the upper end of the thrust ball bearing.
Preferably, the lead screw is sleeved with a large end cover fixed with the box body, the oil seal is in contact with the large end cover, and the upper end of the thrust ball bearing is arranged in the large end cover.
Preferably, the outer wall of the box body is provided with guide keys distributed corresponding to the surface of the screw rod, and the guide keys are fixed with the box body through screws.
Preferably, the upper end of the outer wall of the box body is provided with a straight-through type oil filling cup which is obliquely distributed with the box body.
Before the improvement: because of the self weight of the standard knot, the original standard knot jacking device adopts the characteristics of two plane thrust bearings in the axial direction, can meet the requirement of axial jacking, but cannot guarantee the requirement of radial stability, and has certain dangerous hidden danger.
After the improvement: on the original basis, a radial stressed bearing is added to the direction of the output shaft, so that the requirement of axial jacking can be met, the requirement of radial stability can be guaranteed, and the possibility of hidden danger is greatly reduced.
The structure innovation power of speed reducer is not enough relatively, but the structure of this application file original structure, innovated, promoted the performance of product to a certain extent.
Therefore, the utility model discloses a jacking stabilising arrangement is economized to construction elevator standard, compact structure promotes performance, improves the use accuracy.
