Abstract

The utility model discloses an elevator diverting pulley wears to be equipped with the axle in the diverting pulley, and the axle middle part is equipped with the shaft shoulder, and the bearing is all equipped with to the shaft shoulder both sides, is equipped with the spring between bearing and the shaft shoulder. The spring between the bearing and the shaft shoulder can apply a certain amount of axial force to the bearing, so that the effect of eliminating the oil clearance of the bearing is achieved, and the phenomenon that the rope wheel shakes due to the oil clearance is reduced.

Description

Elevator diverting pulley

Technical Field

The utility model belongs to the technical field of the elevator, concretely relates to elevator diverting pulley.

Background

The existing elevator diversion sheave mainly adopts the structure that a sheave and a shaft are assembled by two parallel bearings, because the distance between the two bearings is very small, and the bearings also have oil gaps, in order to eliminate the rope sheave shaking caused by abnormal sound of the bearings and overlarge oil gaps, two bearing inner rings are basically adopted at two ends of a shaft shoulder of the shaft, an outer ring is in interference fit with an inner hole of the sheave and is clamped to the center, and the oil gaps of the bearings are eliminated, so that the rope sheave shaking caused by abnormal sound of the bearings and overlarge oil gaps is solved. The method is seemingly simple, and the clamping force cannot be ensured, so that the bearing is damaged during assembly and cannot be found and judged; and the shaft is easy to collide in the transportation and installation process, and the bearing is damaged by the axial force.

Disclosure of Invention

The utility model aims to solve the technical problem that an elevator diverting pulley is provided, eliminate bearing oil clearance and reduce the phenomenon that the diverting pulley rocked because of the oil clearance.

In order to solve the technical problem, the utility model discloses a realize through following technical scheme: a shaft penetrates through the elevator diverting pulley, a shaft shoulder is arranged in the middle of the shaft, bearings are arranged on two sides of the shaft shoulder, and a spring is arranged between each bearing and the shaft shoulder.

Further, the spring is a wave spring.

Further, a portion of the spring remains safely compressed.

Furthermore, clamp springs are arranged between the outer side shafts of the two bearings and the diversion sheave.

The utility model discloses an useful part lies in, and a certain amount of axial force can be applyed for the bearing to the spring between bearing and the shaft shoulder to play the effect of eliminating bearing oil clearance, and reduce the phenomenon that the rope sheave rocked because of the oil clearance.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention;

fig. 2 is a partially enlarged view of fig. 1.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments:

as shown in fig. 1 and 2, in the elevator diverting pulley, a shaft 2 penetrates through the diverting pulley 1, a shaft shoulder is arranged in the middle of the shaft 2, bearings 3 are arranged on two sides of the shaft shoulder, a spring 5 is arranged between the bearing 3 and the shaft shoulder, the spring 5 is a wave spring, and the rest part of the wave spring is safely compressed. A clamp spring 4 is arranged between the shaft 2 at the outer side of the two bearings 3 and the reverse rope 1.

The thrust of the wave spring 5 between the bearing 3 and the shaft shoulder applies a certain amount of axial force to the bearing 3 so as to play a role in eliminating the oil clearance of the bearing and reduce the phenomenon that the rope pulley shakes due to the oil clearance. The remaining part of the wave spring 5 is safely compressed and has the following advantages: firstly, the bearing 3 cannot be damaged by axial force due to excessive press-fitting distance during assembly; secondly, when the shaft collides in the transportation and installation process, the shock absorption effect can be achieved, and the bearing 3 is protected from being damaged; and thirdly, when the distance deviation occurs between the center of the diversion sheave 1 and the center of the traction sheave, the central correction function can be realized.

It is to be emphasized that: the above embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form, and any simple modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
