Reinforced bending hoop machine sliding bearings have the advantages of strong bearing capacity, smooth operation, impact resistance, good high-speed performance, etc., but also have some shortcomings, Ss Coil,200 Series Coils,201 Stainless Steel Coil,Stainless Steel Coil Stock Foshan Sunsteel Co. , Ltd , https://www.fssunsteel.com
Such as large starting friction resistance torque, many additional facilities, and more complicated maintenance. Reinforced bending hoop machine sliding bearings are widely used in steam turbines, large motors, vehicles, machine tools, metallurgical machinery, engineering machinery, etc. due to their unique advantages.
In normal operation, unless otherwise specified, the temperature of the friction part of the sliding bearing of the general steel bending hoop machine should not exceed 659C. The main classification of the sliding bearing of the steel bending hoop machine is shown here, and the radial thrust bearing is mainly introduced here.
Technical requirements and installation requirements of the sliding bearing housing of the steel bar bending machine A Technical requirements (1) The joint surface of the bearing housing upper cover and the base after the processing of the bending hoop should be well fitted, and the opening and closing faces the axis position degree of the inner diameter of the bearing housing Tolerance is 0.05mm0
(2) The roughness Ra value of the inner hole surface of the bearing housing and the outer circumferential surface of the bush or bushing should not be greater than 1.65m0
(3) In terms of tolerance matching, the limit deviation of the inner diameter of the bearing housing shall comply with the provisions of H7 in GB 1801, the limit deviation of the outer diameter of the bearing bush shall comply with the provisions of m6 in GB 1801, and the limit deviation of the outer diameter of the sleeve shall comply with the provisions of S7 in GB 1801.
B Installation requirements (1) Coaxiality requirements. When installing the bearing housing, the bearing or sleeve of the bending hoop must be assembled on the bearing housing, and the position correction should be performed according to the center of the shoe or sleeve. That is, first use the thin wire drawing method to check, and then use the contact method to verify it. Then place the shaft on the bearing bush or bushing), and use the display agent (Zhangdan) to check the contact condition on the surface of each bearing bush (or bushing).
(2) Tightness requirements. The bearing seat must be tightly fixed on the body of the bending hoop machine. When the mechanism is running, the bearing seat must not be displaced relative to the body. When the journal rotates, the bush or bushing is not allowed to slide or move in the bearing housing.
