Problems solved by technology
The paper does not calculate the stress and deformation of the rubber, and cannot predict the deflection of the traction sheave under different working conditions
Its core is to propose a symmetrical arrangement of rubber on both sides of the center of gravity, but neither the quantity nor the stiffness of the rubber is involved, nor does it provide a method for the arrangement of vibration-damping rubber in complex traction machine arrangements.

The invention discloses an arrangement method for elevator machine bearing beam vibration-reducing rubber. The arrangement method comprises the following steps that (1) the position of the center of gravity of a system is determined; (2) the arrangement position of the vibration-reducing rubber is determined; (3) support reaction is calculated; (4) the maximum dip angle of an allowable error of calculation of the support reaction is determined; (5) the maximum dip angle of an allowable error in a national standard index is determined; (6) the distance between sliding support seats is determined; and (7) the no-load operating condition and the full-load operating condition are checked. The arrangement method is designed for the vibration-reducing rubber of a traction machine frame or a machine bearing beam, the arrangement position and the corresponding rigidity of the vibration-reducing rubber can be quickly and accurately calculated, practical application under a no-load operating condition, a half-load operating condition, a full-load operating condition and the like is achieved, and the calculation difficulty and the time cost are lowered; and in addition, a calculation model and method are proven to be accurate and reliable through finite element calculation and practical engineering testing, and are particularly suitable for complicated structure arrangement such as oblique arrangement of traction machines.
Description
technical field [0001] The present invention mainly relates to the technical field of elevator vibration reduction, and in particular to a method for arranging vibration-damping rubber of elevator shelving beams. Background technique [0002] Elevators are a type of special equipment widely used in production and life in modern society. At present, the development of machine room-less elevators is relatively rapid. Compared with machine room elevators, modern production technology is used to minimize the equipment in the machine room while maintaining the original performance. The control cabinet and traction machine in the original machine room , speed limiter, etc. are set on the side of the well, thus canceling the traditional machine room, in order to meet the special requirements of customers for height and roof. The vibration when the elevator traction machine is working, the vibration and noise when the brake is operating will be transmitted to the building through t...
