Ball guide shoe

Abstract

The invention discloses a pair of ball guide shoes. The ball guide shoes have the advantages that the operating resistance of an elevator can be reduced, the energy is saved, higher moving speed can be easily obtained, long-time and smooth operation of the elevator can be maintained, the safe and reliable effects are achieved, the service life is long, the installation and the replacement are convenient and the volume is small. Each ball guide shoe comprises a guide shoe seat, wherein a fixed bracket is arranged on the guide shoe seat. The ball guide shoe is characterized in that the center of the fixed bracket is longitudinally provided with a vertical guide system corresponding to a working top surface of a guide rail; the two sides of the guide shoe seat are provided with a left-side guide system and a right-side guide system corresponding to working side surfaces of the guide rail; the vertical guide system consists of a ball frame A, a ball cover A and a ball A which are fixed by bolts; the left-side guide system consists of a ball frame B, a ball cover B and a ball B which are fixed by bolts; the right-side guide system consists of a ball frame C, a ball cover C and a ball C which are fixed by bolts; the vertical guide system, the left-side guide system and the right-side guide system form a concave-shaped sliding groove; and the fixed bracket is provided with guide-shoe outer covers for covering the left-side guide system and the right-side guide system.

Description

technical field [0001] The invention relates to an elevator guide shoe, in particular to a ball guide shoe. Background technique [0002] At present, elevator guide shoes are divided into two types: roller guide shoes and sliding guide shoes. The roller guide shoe is stuck on the guide rail with 3 or 6 wheels, and is generally used for elevators with a speed above 2m / s; its characteristic is that rolling friction replaces sliding friction, which reduces friction loss and reduces the friction loss during operation. The vibration and noise of the guide shoe improve the comfort of the ride, but the processing and installation requirements of this guide shoe are relatively high. The sliding guide shoe is to clamp a "concave" shaped chute on the guide rail. It is generally used for elevators with a speed of less than 2 meters. Its characteristics: the head of the guide shoe is fixed and the structure is simple. But because there is no adjustment mechanism, as the running time o...

Problems solved by technology

However, since there is no adjustment mechanism, as the running time of the elevator increases, the matching gap between the guide shoe and the guide rail will become larger and larger, and the car will shake during operation, and even shocks will occur.
