Centrifugation polymerization integrated metal lining nylon wheel and processing method thereof

Abstract

The invention relates to a centrifugation polymerization integrated metal lining nylon wheel and a processing method thereof. The centrifugation polymerization integrated metal lining nylon wheel comprises an MC nylon rope wheel and a metal lining, the front side and back side of the MC nylon rope wheel are both provided with a 3's integral multiple number of reinforcing ribs, a plurality of annular grooves and/or bulges are arranged in a "-" shape along the axial direction on the outer ring of the metal lining, and a part of the MC nylon rope wheel is embedded in the annular grooves, the bulges are embedded into the MC nylon rope wheel, the front end and tail end of the metal lining's inner ring are symmetrically equipped with two or four check rings for holes. The front end and tail end of the metal lining are also provided with seal end covers, in which framework oil seals are embedded. The method reasonably combines metal and engineering plastics together, effectively overcomes the disadvantages of instability and poor strength of plastic products, and guarantees a permanent clasping force between the metal lining and the MC nylon rope wheel.

Description

technical field [0001] The invention relates to a centrifugal polymerization integrated metal bush nylon wheel and a processing method thereof, belonging to the technical field of nylon wheel casting and processing. Background technique [0002] In the prior art, nylon wheels with metal bushings are widely used in various wheel bodies such as elevator sheaves and crane pulleys due to their own characteristics. The traditional processing technology is to press the metal bushing into the center hole of the nylon wheel. The interference fit keeps the nylon wheel and the metal bushing relatively fixed, but the metal bushing nylon wheel processed by this method cannot dynamically adjust the play between the guide wheel and the bearing when the working temperature of the guide wheel changes. Therefore, it is difficult to ensure the normal operation of the bearing, which affects the quality and service life of the elevator using this metal-lined nylon wheel. [0003] The main disa...

Problems solved by technology

At the same time, because the environment of the elevator is very complicated, the ambient temperature of the elevator may vary between -30°C and 50°C, and the temperature change between the MC nylon wheel and the bearing will cause the two to be too loose ( When the temperature rises) or too tight (when the temperature decreases): When the fit is too loose and the amount of clearance generated is greater than the interference between the bearing and the nylon wheel during assembly, the nylon wheel and the bearing will produce excessive fit and cause both The friction heats up, and because the gap between the bearing and the inner hole of the nylon wheel is small, the heat generated by the friction is not easy to dissipate, which will directly accelerate the wear of the bearing and the nylon wheel, and eventually cause the two to no longer match

The result of this mismatch may be that the bearing produces noise during operation and causes the elevator to vibrate or shake during operation, which affects the quality of the elevator; when the temperature drops and the fit is too tight, the deformation of the nylon wheel is greater than that of the bearing, so that the nylon wheel The cooperation with the bearing becomes tighter and tighter as the temperature decreases, reducing the normal clearance between the two. Over time, the bearing will be damaged, causing the elevator to generate noise and vibration during operation, which will affect the quality of the elevator
