Polyurethane foot wheel

Abstract

The invention discloses a polyurethane foot wheel. The polyurethane foot wheel comprises a base wheel body, the outer wall of the base wheel body is poured with a polyurethane outer wheel body, a flange is formed on one side of the base wheel body, the polyurethane outer wheel body is sleeved with an outer fixing sleeve in an inserted mode, a stop ring is formed on one side of the outer fixing sleeve, the stop ring of the outer fixing sleeve abuts against the flange of the base wheel body, bolts penetrate through the flange of the base wheel body to be in threaded connection with the stop ringof the outer fixing sleeve, a bearing is fixed to the outer fixing sleeve in an inserted sleeved mode, an anti-wear sleeve is fixed to the outer ring of the bearing in an inserted sleeved mode, and an anti-wear ring is formed on the front side of the anti-wear sleeve. The anti-wear sleeve in contact with a guide rail and capable of rotating relatively is arranged on the polyurethane foot wheel, friction between the polyurethane foot wheel and the guide rail can be reduced, defective conditions of operation of a trolley on the guide rail are reduced, and the guide rail is protected.

Description

Technical field: [0001] The invention relates to the technical field of casters, in particular to a polyurethane caster. Background technique: [0002] In the process of transportation and transmission, in order to make the transportation more convenient, transportation devices such as trolleys and flatbed trucks are often used. These transport transmission mechanisms generally use rubber or plastic casters of various shapes. Because the rubber and plastic materials are soft in texture, they can reduce the bumps and shakes caused by contact with the ground during transportation and transmission; because polyurethane is not easy to scratch and has low noise , non-pollution, and wide application temperature range are generally welcomed, so polyurethane casters are popularized. At present, some polyurethane casters with guide rails have a retaining ring formed on one side of the base wheel, which can play a restrictive role when used with guide rails. , but the retaining ring ...

Problems solved by technology

These transport transmission mechanisms generally use rubber or plastic casters of various shapes. Because the rubber and plastic materials are soft in texture, they can reduce the bumps and shakes caused by contact with the ground during transportation and transmission; because polyurethane is not easy to scratch and has low noise , non-pollution, and wide application temperature range are generally welcomed, so polyurethane casters are popularized. At present, some polyurethane casters with guide rails have a retaining ring formed on one side of the base wheel, which can play a restrictive role when used with guide rails. , but the retaining ring is prone to friction with the side wall of the guide rail, and the friction will affect the operation of the trolley and flatbed, and even cause wear and tear on the guide rail, affecting the use of the guide rail
