Embodiment Construction

[0016] The technical contents and embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] attached figure 1 It is a structural schematic diagram of the combined elevator pulley of the present invention, which is the best implementation mode of the present invention.

[0018] According to attached figure 1 It can be clearly seen that the combined elevator pulley structure of the present invention includes two metal half-hubs 2-1 and 2-2, a wheel rim 3, and a bearing sleeve 4 that are identical in shape and specification and fit tightly together. Composition, the tightly fitted half-hubs 2-1 and 2-2 are respectively flat / straight towards the outside of the bell mouth, wherein,

[0019] The middle sections of the half-hubs 2-1 and 2-2 are horn-shaped shells or conical shells,

[0020] The middle of the trumpet-shaped housing or the conical housing of the described half-hub 2-1 and 2-2 is flanged outwards resp...

Abstract

The invention relates to a combined elevator pulley and a manufacturing method thereof. The combined elevator pulley is composed of the three parts comprising two metal half hubs with the same shape and size which cling to each other, a collar rim and a bearing sleeve, wherein, the center section of the half hub is a horn or cone shell, the middle of the half hubs roll outward or connect with a cylinder respectively, the cylinder and the bearing sleeve match with each other; the half hubs are stretched or connected with a cylinder respectively on the outside; the upper or the so-called external part of the cylinder has a collar rim which is made from wearable polymer material, the collar rim is provided with a grooving and used as elevator wheel. Furthermore, the invention provides a manufacturing method of the combined elevator pulley. The invention is widely used in anyplace which needs to install wheels, the production has the advantages of light weight, simple structure, good strength, low cost, safe and reliable use, energy-conservation and environment protection, and is substitute of traditional casting wheel, especially can be substitute of elevator wheel like crosshead sheave, counterweight sheave and guide wheel.

Description

technical field [0001] The invention relates to a combined elevator pulley and a manufacturing method thereof, which can be used as a substitute for traditional casting wheels, and is especially suitable for elevator pulleys, such as car top wheels, counterweight wheels and guide wheels. Background technique [0002] With the development of the economy and the improvement of people's living standards, the development prospect of the elevator industry is getting better and better, and the demand for a new generation of green elevators, energy-saving elevators and intelligent elevators is becoming stronger and stronger. Pulleys with larger diameters are the main components of elevators, such as car top wheels, counterweight wheels, guide wheels, etc. At present, the manufacturing method of pulleys for elevators is mainly to cast and then machine. This traditional manufacturing method is difficult to machine when manufacturing wheels with large wall thickness and weight. As t...
