Abstract

The utility model discloses an inserted combined traction wheel. A wheel groove is arranged on a wheel body, groove keys are arranged on groove shoulders, each ring of groove shoulders are divided into from two to four equal parts, and are inserted in the wheel groove on the wheel body via the groove keys, the groove shoulders are fixed on the wheel body via screws, and so, when the groove shoulders of the traction wheel are worn out, only the groove shoulders need changing, without changing a whole traction wheel. Change workload is little, cost is saved, and work efficiency is increased. The utility model is used for a traction construction lifter.

Description

Setting-in compound type traction sheave

The utility model relates to a kind of traction sheave, especially a kind of setting-in compound type traction sheave.

Widely used traction sheave is an integral type on the elevator now, be that the groove shoulder is an one with wheel body, it is formed by one section cylindrical metal cutting, and its traction groove is to form by the metal that turning is fallen on the wheel body, so its cutting amount is big, stock utilization is low, cost is high; Moreover the shortcoming that the integral type traction sheave is fatal be when steel rope at traction groove internal friction, skid and wear grooves shoulder makes traction sheave time spent again, must change whole traction sheave, even the groove of traction groove shoulder is worn when causing the steel cable cisco unity malfunction, in order to guarantee safety, also to change whole traction sheave, influence work efficiency like this, and the expense height.

The purpose of this utility model be to provide a kind of when the groove shoulder only need change when being worn groove shoulder, that reduce expenses, change the little setting-in compound type traction sheave of work capacity.

The utility model is to realize above-mentioned purpose like this: setting-in combination traction groove, comprise wheel body and groove shoulder, race is arranged on the wheel body, on the groove shoulder sunk key is arranged, every ring recess shoulder is divided into 2～4 equal portions and is inlaid in the race on the wheel body by sunk key, the groove shoulder on wheel body, has just formed traction groove between adjacent every ring recess shoulder by screw retention.

Because groove shoulder of the present utility model is the setting-in compound type with wheel body, when groove of the present utility model is takeed on by abrasion, need not to change whole traction sheave, as long as the groove shoulder of abrasion is pulled down, the groove shoulder that more renews gets final product, so it is little to change work capacity, reduce expenses, improved work efficiency.

Below in conjunction with accompanying drawing the utility model is done concrete detailed description the in detail.

Fig. 1 is the cutaway view of wheel body;

Fig. 2 is the front view of groove shoulder;

Fig. 3 is a cutaway view of the present utility model.

With reference to Fig. 1, radially race 8 is arranged on the outer ring of wheel body 3, with reference to Fig. 2, on the groove shoulder 2 sunk key 7 and bolt hole 5 are arranged, groove shoulder 2 is divided into 3 equal portions, goes in the race 8 on the wheel body 3 so that groove can be takeed on 2 sunk key 7 setting-ins; With reference to Fig. 2, Fig. 3, every ring recess shoulder 2 is divided into 3 equal portions, and in the race 8 on the sunk key 7 setting-in wheel bodys 3, groove shoulder 2 is fixed on the wheel body 3 by screw 4.

For sunk key 7 setting-ins that make groove shoulder 2 are gone in the race 8 on the wheel body 3, groove shoulder 2 must be divided into 2～4 equal portions, with reference to Fig. 2, part preferably classifies in three categories, and must guarantee to have 2 bolts hole 5 at least on every equal portions groove shoulder 2, correspondingly also screw hole should be arranged in the race 8 on the wheel body 3, so that hold down groove shoulder 2.

Claims
