Light MC (monomer casting) nylon carrier roller for light loads and method for manufacturing light MC nylon carrier roller

Abstract

The invention discloses a light MC (monomer casting) nylon carrier roller for light loads and a method for manufacturing the light MC nylon carrier roller. The light MC nylon carrier roller comprises a roller body, a carrier roller shaft, a bearing block, a bearing, an inner sealing ring, an anti-jamming check ring, a dustproof sealing clamp, a sealing felt, an outer sealing ring and a clamp spring. An even number of assembling rib plates are arranged on the outer wall of the bearing block, and the anti-jamming check ring is arranged on the outer side of the bearing block and is fixed when the carrier roller rotates, so that damage to the carrier roller due to materials accumulated beside a belt conveyor can be prevented. The method includes combining an aluminum foil bag with molding sand to manufacture a die core of a die for manufacturing the light MC nylon carrier roller for the light loads; filling the molding sand into the aluminum foil bag to form the die core; coating release agents on the outer wall of the aluminum foil bag; taking out the molding sand from the aluminum foil bag after casting is completed; directly forming a center hole of the roller body of the carrier roller. The light MC nylon carrier roller and the method have the advantages that raw materials can be reduced, a barrel core machining procedure can be omitted, accordingly, the roller body of the carrier roller can be formed at one step, the raw materials and the machining cost of the roller body of the carrier roller can be reduced, and the straightness and the cylindricity of the carrier roller can be guaranteed.

Description

technical field [0001] The patent of the invention belongs to the technical field of belt conveyor transmission, as well as the light-weight and light-load MC nylon idler roller and its manufacturing method, and is especially suitable for belt conveyors with small transportation volume under harsh working conditions. Background technique [0002] The belt conveyor is a kind of continuous transportation equipment that uses the belt as a traction mechanism and a load-bearing mechanism. It has the advantages of large transportation capacity, small transportation resistance, low power consumption, stable transportation, and little damage to materials during transportation. It is widely used in mines. Surface and underground are extremely widely used. The idler roller is a part that carries the conveyor belt so that the sag does not exceed the limit value to reduce running resistance and ensure the smooth operation of the belt conveyor. The idlers are distributed along the entir...
