Plate-type composite steel belt leading sheave

Abstract

The invention discloses a plate-type composite steel belt leading sheave. The plate-type composite steel belt leading sheave comprises a guide groove. The plate-type composite steel belt leading sheave is characterized in that the guide groove is a flat-bottomed groove. The plate-type composite steel belt leading sheave not only can achieve automatic centering of a composite steel belt, guarantee smooth running of the composite steel belt in the guide groove, and completely avoid the phenomenon of passline deflection of the composite steel belt, but also can further improve a stress state of the composite steel belt, prolong the service life of the plate-type composite steel belt leading sheave, and meanwhile reduce vibration and noise. The plate-type composite steel belt leading sheave can be used for a dragging and running wheel on an elevator, a guide pulley, a car roof wheel, a car bottom wheel, a counterweight wheel and the like, really be suitable for a long-time running of the elevator, simplify installation technology of the elevator, and meanwhile guarantee the service life of the composite steel belt.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a pulley used for guiding a flat composite steel belt. The pulley is mainly used as a traction wheel, a guide wheel, a car top wheel, a car bottom wheel, a counterweight wheel, etc. on an elevator. Background technique [0002] As a vertical transportation tool, elevators are closely related to modern social life. With the development of social economy and the acceleration of urbanization, there are more and more high-rise buildings, and high-rise buildings have become a city symbol, some even Become a landmark of the city. With the emergence of high-rise buildings and the development of social culture, the demand for elevators is becoming stronger and stronger, especially in today's aging society, the significance of elevators is even more important. Elevators all over the world are in operation every day, carrying a large number of people and logistics transportation. The role of elev...

Problems solved by technology

[0005] There are also some designs that use a concave-convex composite steel strip, such as Chinese patent 200810061529.9, which is to change the shape of the composite steel strip, increase the concave-convex surface (or use a V-ribbed belt), and make the concave-convex surface correspondingly on the wheel groove, although it can also be effective Realize the guidance of the composite steel belt, but the fatal flaw of this structure is that the friction coefficient between the composite steel belt and the wheel groove is relatively large, and the composite steel belt cannot slip. The steel wire rope slips on the sheave, and this structure cannot achieve slippage, so its application is very limited

In addition, the cost of producing this kind of concave-convex composite steel strip is more expensive than that of ordinary flat steel strip
