Abstract
The invention relates to a driving wheel fixing part in an elevator gear reducer box. A driving wheel comprises a gear-shaped wheel body and a boss projecting over one side of the wheel body, the axial outer end of the boss is provided with a circular groove coaxial with the wheel body, and one side of the boss of the driving wheel faces a cover plate of the gear reducer box. The driving wheel fixing part is characterized by comprising a columnar limit rod and a platy connecting portion, wherein the columnar limit rod transversely extends and is matched with the groove, and the platy connecting portion longitudinally extends. The driving wheel fixing part is independent of the cover plate of the gear reducer box, the limit rod is small in sectional area and low in abrasion, and the whole fixing part is convenient to replace. A damping structure can be arranged on the periphery of the limit rod, friction between the driving wheel and the fixing part can be decreased so that the driving wheel rotates more stably, and noise is reduced.

Background technique
The power equipment of elevator mainly is a hoist machine, specifically comprises motor, break, coupling, speed reducer, traction sheave and frame.Wherein, speed reducer comprises casing and drive wheel.Drive wheel comprises the boss of gear shape wheel body and protrusion wheel body one side.Wheel body one side end face of drive wheel and transmission shaft is affixed and be rotatably connected in the speed reducer casing through transmission shaft is enclosed in the cover plate in the casing with drive wheel on the casing, and said cover plate is parallel relatively with boss one side end face of tradition wheel.Usually the through hole that setting cooperates with said boss profile phase on cover plate is as supporting structure; Reduce the speed reducer intermediate solid drive shaft and drive the circular runout that produces when drive wheel rotates; Increase stability, still, in drive wheel constantly rotates; Friction between boss and cover plate through hole causes damage to cover plate easily, and bringing needs often to change the inconvenience of cover plate and the increase of cost.
Summary of the invention
The present invention has overcome the deficiency of existing technology, provides a kind of simple in structure, and it is little to wear and tear, and it is convenient to change, the drive wheel fixed block in the elevator gear reducer box that transmission of power is stable more, noise is low.
For achieving the above object; The technological scheme that the present invention adopts is: the drive wheel fixed block in a kind of elevator gear reducer box; Said drive wheel comprises the boss of gear shape wheel body and protrusion wheel body one side; Said boss axial outer end is provided with the circular groove coaxial with wheel body, and boss one side of said drive wheel is characterized in that to the speed reducer cover plate: comprise the column position-limited lever of horizontal expansion and said groove fit and the sheet joint of longitudinal extension.
In preferred embodiment of the present invention, the diameter that further comprises said position-limited lever is less than boss groove internal diameter, and the upper edge, four positions that the position-limited lever cross-wise direction is mutually an angle of 90 degrees correspondence separately radially is provided with damping spring.
In preferred embodiment of the present invention, comprise further between position-limited lever and the joint of said drive wheel fixed block also being provided with the column reinforcing part that said reinforcing part diameter is greater than the position-limited lever diameter.
In preferred embodiment of the present invention; Further comprise said position-limited lever, reinforcing part, the coaxial setting of joint; The joint cross-wise direction has four fixed holes that are mutually an angle of 90 degrees, and the circumferential position of said four fixed holes is corresponding one by one with the position of said four damping springs.
In preferred embodiment of the present invention, comprise that further said position-limited lever diameter is 4/5 of a said boss groove internal diameter.
In preferred embodiment of the present invention, comprise that further said reinforcing part diameter is spacing shank diameter 3-4 times.
The invention solves the defective that exists in the background technique, drive wheel fixed block of the present invention is independent of the speed reducer cover plate, and the position-limited lever sectional area is little, and it is little to wear and tear, and whole fixed block is changed convenient.Can shock-damping structure be set in the position-limited lever periphery, help reducing the friction between drive wheel and fixed block, it is more steady that drive wheel is rotated, and reduces noise simultaneously.

Embodiment
Combine accompanying drawing and embodiment that the present invention is done further detailed explanation now, these accompanying drawings are the schematic representation of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
Shown in Fig. 1-3; Drive wheel fixed block in a kind of elevator gear reducer box of the present invention; Said drive wheel comprises the boss 3 of gear shape wheel body 1 and protrusion wheel body 1 one sides; Said boss 4 axial outer end are provided with the circular groove 31 coaxial with wheel body 1, and boss 3 one sides of said drive wheel are to speed reducer cover plate 5.Said drive wheel fixed block comprises the cylindric position-limited lever 2 that horizontal expansion matches with said groove 31 and the round sheet joint 6 of longitudinal extension.Also be provided with column reinforcing part 4 between the position-limited lever 2 of said drive wheel fixed block and the joint, position-limited lever 2, reinforcing part 4, joint 6 coaxial settings, and reinforcing part 6 diameters are 3.5 times of position-limited lever 2 diameters.The diameter of said position-limited lever 2 is 4/5 of said groove 31 internal diameters; The upper edge, four positions that position-limited lever 2 free end cross-wise direction are mutually an angle of 90 degrees correspondence separately radially is provided with damping spring 21, and each damping spring 21 natural length is greater than 1/10 of said boss groove 31 internal diameters.Joint 6 cross-wise direction are provided with four fixed holes 61 that are mutually an angle of 90 degrees, and the circumferential position of said four fixed holes 61 is corresponding one by one with the position of said four damping springs 21.
During installation; Position-limited lever 2 free ends of said drive wheel fixed block are inserted the groove 31 of said boss; Wherein a pair of damping spring 21 is positioned at vertical position; Another is positioned at horizontal position to damping spring 21, and is remained static by place place's groove 31 inwall vertical compression respectively, leaves the space between position-limited lever 2 free end end faces and groove 31 bottom surfaces.With above-mentioned damping spring 21 positions correspondingly, in four fixed holes 61 on the said joint 6, a pair of vertical position that is in is arranged also, a pair of being horizontal is fixed in the residing speed reducer cover plate 5 of drive wheel through screw with joint 6.Adopt the realization of 31 pairs of drive wheels of position-limited lever 2 insertion boss grooves radially spacing, dwindled area of contact, i.e. frictional force; Position-limited lever 2 and drive wheel boss 3 all there are the certain protection effect, simultaneously, only need to install four damping springs 21 of vertical position each other on the position-limited lever 2; Just can to drive wheel radially play good cushioning effect, reduced drive wheel beating radially, more steady; Also avoided of direct the contacting of position-limited lever 2 outer walls in addition with boss groove 31 inwalls; Can damping spring 21 and position-limited lever 2 be made as the mode of flexible connection, in case damping spring 21 wearing and tearing only need exchange buffering spring 21 to get final product.
Above foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must confirm technical scope according to the claim scope.
