Description

Technical Field

[0001] The utility model belongs to the technical field of mobile equipment, and in particular relates to a roller device with side wheels which is used in conjunction with a grooved guide rail and can reduce wear of the roller device itself and the grooved guide rail. Background Art

[0002] Rollers are a type of component widely used in various industrial fields. They transmit motion and reduce resistance by rotating the rollers. Rollers have a wide range of applications, such as forklift lifts, hydraulic cargo elevator platforms, and other equipment that slide between guide rails. Rollers need to be installed to guide the movement of the equipment. However, in actual use, it is found that while the rollers are rolling, their sides are prone to friction with the sides of the guide rails, resulting in a large gap between the sides of the rollers and the sides of the guide rails due to wear, affecting the stability of the equipment operation and the service life of the rollers and guide rails.

[0003] To this end, technicians added side wheels to the sides of the rollers, and changed the sliding friction between the sides of the rollers and the sides of the guide rails to rolling friction, thereby reducing wear. The side wheels were installed in the inner cavity of the wheel axle of the roller through side wheel seats. However, it was found during actual use that when the side wheels were in contact with the guide rails, under the action of friction, the side wheel seats would rotate relative to the wheel axle due to the transmitted friction, causing the side wheels to flip over, resulting in poor stability of the side wheels. In addition, there was a gap between the side wheels and the side wheel seats, and wear debris and debris could easily enter between the side wheel seats and the side wheels through the gap, thereby affecting the service life of the side wheels.
