Problems solved by technology

[0005] However, when the weight of the above-mentioned cage 31 or counterweight 32 is reduced, the frictional force between the pulley 35 and the elevator cable 33 will be reduced due to the reduction in weight, and thus the driving force output by the lifting winch will not be effective. The control of the steel cable 33 transmitted to the elevator is poor, and there is a problem that the cage 31 cannot be safely driven by people or objects
In other words, it is quite difficult to reduce the weight of the lift

Embodiment 1

[0051] The surface layer 11 is neoprene, and its hardness is set at 63 degrees, and the inner middle layer 15 is also neoprene, and its hardness is also set at 63 degrees. As a result, the load was 104 kgf.

Embodiment 2

[0053] The surface layer 11 is neoprene, and its hardness is set at 63 degrees, and its inner middle layer 15 is also neoprene, and its hardness is set at 80 degrees. As a result, the load was 120kgf.

Embodiment 3

[0055] The surface layer 11 is neoprene, the hardness is set to 80 degrees, and the middle layer 15 inside it is also neoprene, and the hardness is set to 80 degrees. As a result, the load was 98kgf.

Abstract

Elevator drive belts (5) driving an elevator rope (3) connecting the car (1) of an elevator to a counterweight (2) while applying a frictional force thereto, wherein the rubber hardness of the belts is set to approx. 50 to 90 DEG to suppress a creep slip due to a shearing strain during the operation of the elevator, whereby even if the frictional force applied to the elevator rope (3) is reduced due to a reduction in the weight of the elevator caused by a reduction in the weight of the car (1) and the counterweight (2), the drive force of the elevator can be guaranteed by the frictional force applied from the elevator drive belts (5) to the elevator rope (3).

Description

technical field [0001] This invention relates to belts for elevator drives. Background technique [0002] Up to now, elevators are still used, which allow people or goods to be carried in a cage-shaped container and carried between floors of a building in a longitudinal direction. [0003] Such as Figure 8 Shown, this elevator is the elevator steel cable 33 that is made with steel wire, and the cage 31 (car) that rides people or article is connected with balance weight 32 (counterweight), and this elevator steel cable 33 is wound on the elevator. The hoisting winch 34 (motor) at the top of the passage is suspended on the pulley 35 and operates in a suspended manner. [0004] Therefore, if the weight of the cage 31 or the weight 32 can be reduced, the cost of the entire elevator can be reduced, and the burden on the building can also be reduced. [0005] However, when the weight of the above-mentioned cage 31 or counterweight 32 is reduced, the frictional force between the...
