AI Technical Summary

Problems solved by technology

For large-scale load-bearing equipment, the connection structure is relatively fragile, and the connection structure will become loose after a long time, which will affect the safety of production
On the premise that the alloy steel plate material is widely used, the above-mentioned pulley still lacks the anti-slip and anti-off force in the radial and transverse directions.

Embodiment 1

[0022] Embodiment 1, as shown in FIGS. 1-2 , the assembled pulley of the present invention mainly includes a bearing support 1 , a main spoke 2 , an auxiliary spoke 3 and a wheel rim 4 . in,

[0023] The bearing support body 1 and the main spoke 2 are cast into an integrated structure, while the auxiliary spoke 3 is set separately from the bearing support body 1 .

[0024] The main spoke 2 and the auxiliary spoke 3 are symmetrically positioned and oppositely provided with several bolts 21 along the circumferential direction of the bearing support body, and the auxiliary spoke 3 and the wheel rim 4 are fixedly connected to the main spoke 2 through the fastening force of the bolts. The rim 4 is clamped and fastened between the main spoke 2 and the auxiliary spoke 3 .

[0025] The rim 4 is equally divided into two symmetrical parts, and a sprocket groove 41 is arranged on the outer periphery thereof.

[0026] Several protrusions 22 are provided on the main spoke 2 and the auxil...

Abstract

The present invention relates to combined assembled pulley and provides a new kinds of combined pulley structure. The assembled pulley has the parts designed and manufactured separately and assembled properly without unloosening and separation. The assembled pulley includes mainly bearing support, main spokes, secondary spokes and felloe, and the bearing support and the main spokes are cast integrally.

Description

technical field [0001] The invention relates to an improved scheme of a new type of pulley with combined assembly structure and applied to large lifting or transportation equipment. Background technique [0002] Currently used in large-scale lifting and transportation equipment in industrial and mining enterprises, port stations and other places, pulley assemblies with larger profiles are generally used. Since the existing large pulleys are generally made by casting or rolling, if the spokes and the rim of the integral pulley are of an integrated structure, the wheel rim is easily damaged after long-term use, which will affect the stability of the pulley assembly. Replacing the entire pulley due to damaged rims is not only a huge waste of money, but the entire replacement process is time-consuming and labor-intensive. Especially when the pulley is applied to large-scale equipment such as port ship unloaders and door cranes, it takes a long time for maintenance due to the la...
