Embodiment 1

[0028] according to figure 1 The structure and production method of the present invention are described in detail. The titanium-steel composite elevator traction sheave includes a wheel rim with a traction rope groove, a wheel spoke, a shaft sleeve and the like. Wherein, the rim is a titanium-steel composite structure, the traction rope groove is arranged on the outer side of the titanium alloy layer 1 of the rim, and the rim is welded to the spokes through the carbon steel layer 2 of the rim. The spoke is a sandwich structure consisting of spoke carbon steel layer 2-spoke foam aluminum layer 4-spoke carbon steel layer 2, and the axle sleeve 5 is welded to the spoke. The traction rope groove can be processed into a semicircular groove or a concave groove or a V-shaped groove.

[0029] The production method of the titanium-steel composite elevator traction sheave comprises the following steps:

[0030] 1) Preparation of titanium-steel composite pipes and low-carbon steel Q23...

Embodiment 2

[0042] In step ②, the thickness ratio of the titanium tube blank layer to the short steel tube layer is 5:3, and other steps are the same as in embodiment 1.

Abstract

A titanium steel composite elevator traction wheel comprises a rim, spokes and a shaft sheath, and adopts the technical points that the rim adopts a titanium steel composite structure, a traction rope slot is formed in the outer side of the titanium alloy layer of the rim, and the rim are welded together with the spokes through the carbon steel layer of the rim; each spoke adopts a sandwich structure comprising a spoke carbon steel layer, a spoke foam aluminum layer and another spoke carbon steel layer; the shaft sheath is welded together with the spokes. The traction wheel provided by the invention fundamentally solves the problems that the traction force of a half slot traction wheel is low due to the low friction coefficient of the carbon steel material of a high speed elevator traction wheel and the limitations from a V-shaped slot traction wheel are high. Moreover, the titanium steel composite elevator traction wheel provided by the invention adopts a composite structure, is light in weight and has wave absorbing and shock absorbing functions.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to a titanium-steel composite elevator traction sheave and a production method thereof. Background technique [0002] The traction sheave is the sheave on the traction machine of the elevator, also known as the traction sheave or the rope driving sheave of the elevator. It is a device for the elevator to transmit the traction power. Friction transmits power. The existing traction sheave is usually made of ductile iron. The traction force of the traction sheave driving the elevator is generated by the friction between the traction rope and the traction sheave groove. Therefore, the shape of the traction sheave groove is directly related to the The size of the traction force and the life of the traction rope. The shape of the traction sheave rope groove includes a semicircular groove, a semicircular groove with a cutout (also known as a concave groove), a V-shaped groove,...
