The function of the elevator traction system is to output and transmit power to drive the elevator. It is mainly composed of traction machine, traction wire rope, guide pulley and reverse sheave. The towing machine provides power for the operation of the elevator, which is composed of motor, towing wheel, coupling, reducer and electromagnetic brake. Both ends of the pulling wire are connected to the lift car and counterweight respectively, and the lift car is driven up and down by the friction between the wire rope and the pulling wheel. The guide wheel is used to separate the space between the lift car and the counterweight. The use of compound winding type can also increase the drag force.

Metal-based inlaid solid self-smooth bearing (JDB for short) is a novel smooth bearing with both metal bearing characteristics and self-smooth bearing characteristics; it is loaded by a metal substrate; the uniquely formulated solid smooth material has a smoothing effect. High; impact resistance; high temperature resistance; self-smoothing and strong features; uniquely suitable for heavy loads; low speed; reciprocating or rocking, etc., difficult to smooth and constitute oil film; not afraid of water rushing and other acid etch and erosion. The user reflects the inlaid bearing not only fuel saving; energy saving; and its working life is longer than that of ordinary sliding bearings. The current products have been widely used in metallurgical continuous casting machines, rolling equipment, mining machinery, ships, steam turbines, hydraulic turbines, injection molding machines and Equipment production line. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
1. The unique production process is due to the unique production process; some key equipment of industrial and mining companies operate under extremely harsh working conditions. Because of heavy equipment and high ambient temperature; dust or air containing acid corrosive gas CO; SO2; The sleek brings many problems; the conflict wears severely; so far; most of the above-mentioned companies in the country still follow the traditional oil and grease smoothness; in fact, these industrial and mining conditions have exceeded the scale of oil and grease smooth; Other bites or bites of conflict; incurs severe wear and damage of parts; often incurs equipment outages. In order to produce continuous operation; in addition to the need to install multiple equipment wheel repairs on the original depiction; Personnel. Strictly constrains the progress of yield; spare parts and energy consumption are extremely large; it has become an important obstacle to the development of production. Automobile production, cement production, petrochemical and other companies have put forward the demand for special smooth materials under the conditions of chaotic conditions. For this purpose; research on mosaic self-smooth composite materials; outstanding characteristics in data formulation and preparation process The data function has reached the international advanced level; the company has dealt with the slick problem under the unique working conditions; and brought significant economic and social benefits. However, because of various reasons, more companies in the country have not used it; presence.
2. Key technical principle The inlaid self-smooth composite material is a new type of anti-extremely pressed solid smooth material; it consists of a metal substrate and a solid smoothing paste embedded in the hole or groove of the substrate. The metal substrate is in the process of conflict. The vast majority of the load. The conflict; the solid smoothing agent in the hole or the groove is transported or reversed to the conflicting surface; the solid transport film which is smooth and outstanding, firmly attached and evenly covered on the conflict surface; greatly reduces the conflict wear. As the conflict progresses; the embedded solid smoothing agent is continuously supplied to the conflict surface; it ensures the outstanding smoothness of the conflicting pair during long hours of operation.
