Fixing and connecting method for bearing and wheels

Abstract

The invention relates to a method for fixing and connecting bearing and wheel, used to connect small rolling wheel, sliding wheel and bearing, wherein said method is characterized in that: the inner wall of axial hole is arranged with concave; using two fixing rings with tooth plugs to clamp the bearing and the wheel at two end surfaces of bearing and wheel; the tooth plug is inserted into the concave of wheel; the tooth of plug are meshed; there are at least three concaves on wheel; the number of tooth plugs is the same as the concaves of wheel. The invention has low cost without hurting the bearing and wheel, to confirm the long service life of wheel and bearing. The invention can change the condition that the wheel can be only made from plastic.

Description

Technical field: [0001] The invention designs a fixed connection method of a bearing and a wheel, which belongs to the mechanical field, and is especially small in appearance, and is used for the connection method of rolling wheels and sliding wheels of building doors and windows and bearings. Background technique: [0002] In order to reduce the weight and cost of the existing rolling wheels and sliding wheels used for building doors and windows, the above-mentioned rolling wheels and sliding wheels are usually plastic wheels, and the connection method between the wheels and the bearings is to wrap the metal bearings on the outer edge of the metal bearings first. Layers of plastic are then injected to complete the wheel. During the high-temperature injection molding process, the composition of the lubricating oil in the bearing will be damaged to a certain extent, which will affect the use effect of the bearing. In addition, the above-mentioned connection method between th...

AI Technical Summary

Problems solved by technology

In the high temperature injection molding process, the composition of the lubricating oil in the bearing will be damaged to a certain extent, so it will affect the use effect of the bearing

In addition, the above-mentioned connection method between the wheel and the shaft is only applicable to the connection between the plastic rolling wheel and the sliding wheel and the bearing.

However, when plastic material rolling wheels and sliding wheels are applied to building doors and windows, their service life is relatively short.

In addition, some fixing methods of wheels and axles will also cause damage to the axles.
