Abstract
The utility model discloses an elevator special bearing type rope pulley, which comprises a pulley body and a central shaft. The central shaft is arranged in the central through hole of the pulley body. The elevator special bearing type rope pulley is characterized in that a bearing is arranged between the outer wall of the center shaft and the inner wall of the central through hole. Compared with a conventional rope pulley adopted by an elevator, the elevator special bearing type rope pulley is simple in structure, easy to machine, longer in service life and lower in maintenance cost.
Description
Technical field
The utility model relates to a kind of improvement of elevator sheave, specifically a kind of elevator special bearing formula rope sheave.
Background technology
Rope sheave is the essential parts of traction elevator, and this rope sheave is made up of wheel, copper sheathing, axle and screw, and axle is cylindric, and outer wall is a smooth surface; In the central through hole of wheel, be provided with copper sheathing, an end edge of copper sheathing is screwed on the outer wall of wheel, and axle is located in the centre hole of copper sheathing; Copper sheathing is little free-running fit with axle, and copper sheathing cooperates for slight interference with wheel, and its weak point is: copper sheathing is easy to wear; Life-span is short, and the maintenance processing copper sheathing cycle is long, axially occurs displacement easily.
Summary of the invention
The purpose of the utility model is to provide a kind of processing simple in structure, easy, can prolong the rope sheave life-span, saves the elevator special bearing rotary type rope sheave of service expenditure.
In order to reach above purpose; The technical scheme that the utility model adopted is: elevator special bearing formula rope sheave; Be made up of wheel body and center shaft, center shaft is located in the central through hole of wheel body, it is characterized in that: be provided with bearing between the central through hole inwall of said center shaft outer wall and wheel body.
The utility model is also implemented through following measure: the middle part of said center shaft is provided with boss; The sheathed bearing of difference on the center shaft of boss both sides; Two ends at the central through hole inwall of wheel body are respectively equipped with the back-up ring draw-in groove; Back-up ring is located in the back-up ring draw-in groove, and back-up ring is positioned at the outside of the bearing of a corresponding side.
The beneficial effect of the utility model is: compare with the rope sheave that uses on the present elevator, simple in structure, easy processing has prolonged the rope sheave life-span, has saved service expenditure.
Description of drawings
Fig. 1 looks scheme drawing for the structure master of the utility model;
Fig. 2 is the cross-sectional schematic of the structure of the utility model along central axis.
The specific embodiment
Make the utility model with reference to accompanying drawing 1,2.This elevator special bearing formula rope sheave is made up of wheel body 1 and center shaft 3, and center shaft 3 is located in the central through hole of wheel body 1, it is characterized in that: be provided with bearing 2 between the central through hole inwall of said center shaft 3 outer walls and wheel body 1.
The middle part of said center shaft 3 is provided with boss 5; Sheathed bearing 2 respectively on the center shaft 3 of boss 5 both sides is respectively equipped with the back-up ring draw-in groove in two ends of the central through hole inwall of wheel body 1, and back-up ring 4 is located in the back-up ring draw-in groove; Back-up ring 4 is positioned at the outside of the bearing 2 of a corresponding side; Like this, the outer end of bearing 2 is fixing through back-up ring 4, and the inner of bearing 2 is fixing through center shaft 3 convex platforms 5.
