CN201704031U - Built-in anti-seizing side roller of forklift truck - Google Patents

Abstract

The utility model relates to a built-in anti-seizing side roller of a forklift truck, comprising a side roller bracket, a side roller and a side roller shaft, and the side roller is mounted on the side roller frame through the side roller shaft. The built-in anti-seizing side roller of a forklift truck is characterized in that rollway nests are milled at two end faces of the side roller; and a sleeve ring comprising a washer with a rollway nest, a steel ball and a retaining frame component is embedded between the rollway nest and the side roller bracket. The built-in side roller of a forklift truck hast he advantages of bearing an axial force through arranging the rollway nest at two end faces of the side roller and embedding the sleeve ring which is arranged between the rollway nest and the side roller bracket and comprises the washer with a rollway nest, the steel ball and the retaining frame component so that the sleeve ring and the end face rollway nest of the side roller form a thrust ball bearing; greatly reducing friction coefficient as the sleeve ring and the end face of the side roller are in rolling friction instead of sliding friction of the conventional structure when the side roller receives axial pressure, avoiding the seizing phenomenon caused by the rapid abrasion of the side roller and the side roller bracket, and prolonging the service life.

Description

Forklift built-in anti-jamming side rollers

technical field

The utility model relates to a bearing, in particular to a built-in anti-jamming side roller of a forklift.

Background technique

The built-in side rollers of traditional forklifts include brackets, side rollers and axles, and the side rollers are mounted on the brackets through the axles. Its disadvantages are: during the use of the side roller of the forklift, due to the axial force, sliding friction is formed between the end surface of the side roller and the bracket, and the bracket is easily stuck after wear and tear, and the service life is short.

Utility model content

The technical problem to be solved by the utility model is to provide a built-in anti-jamming side roller of a forklift, so that there is no friction between the side roller and the bracket to avoid jamming.

In order to solve the above technical problems, the technical solution of the utility model is: a forklift built-in anti-jamming side roller, including a side roller bracket, a side roller and a side roller shaft, the side roller is installed on the side roller bracket through the side roller shaft, The innovation point is that: the two ends of the side roller are processed with an annular raceway, and a ferrule composed of a washer with a raceway, a steel ball and a cage assembly is embedded between the raceway and the side roller bracket.

The utility model has the advantages that: by setting raceways on both ends of the side rollers, and inserting a ferrule composed of a washer with a raceway, a steel ball and a cage assembly between the raceway and the side roller bracket, the ferrule and The end raceways of the side rollers form a thrust ball bearing, enabling it to withstand axial forces. When the side roller receives axial pressure, there is rolling friction between the ferrule and the end face of the side roller instead of the sliding friction of the traditional structure, which greatly reduces the friction coefficient and avoids the jamming phenomenon caused by the rapid wear of the side roller and the side roller bracket , improve the service life.

Description of drawings

Fig. 1 is a structural schematic diagram of the built-in anti-jamming side roller of the utility model forklift.

Fig. 2 is a schematic diagram of the structure of the utility model ferrule.

Detailed ways

As shown in Figures 1 and 2, it includes a side roller bracket 1, a side roller 2, a side roller shaft 3, a ferrule 4, a washer 5, a steel ball 6, and a cage 7.

The above-mentioned side roller 2 is installed on the side roller bracket 1 through the side roller shaft 3, and the two ends of the side roller 2 are provided with indented cavities, and the end surface of the cavity is processed with an annular raceway. The ferrule 4 is composed of a washer 5, a steel ball 6 and a cage 7, which is embedded between the cavity on the end surface of the side roller 2 and the side roller bracket 1, so that the ferrule 4 and the end surface raceway of the side roller 2 form a built-in Thrust ball bearings capable of bearing axial force on the side roller bracket 1.

Claims (1)

1. built-in anti-blocking side roller wheel of forklift, comprise side wheel support, side wheel and sidewinder wheel shaft, this side wheel passes through the side wheel axle mounting on the side wheel support, it is characterized in that: the both ends of the surface of described side wheel are processed with a ring raceway, and are embedded with between this raceway and side wheel support by the packing ring of band raceway and the lasso that steel ball, retainer assembly constitute.
