Description

The bearing roller of seat damper

Technical field

This utility model belongs to seating art field, refers in particular to a kind of bearing roller of seat damper.

Background technology

For the terminal of driver and seat uses the comfortableness and service life for for client, pursuing product and can It is requisite by property, all wants that one comfortable, failure is few, life-span length seat.Seat vibroshock bearing roller Occur being exactly to meet comfortableness and lifting the seat damper life-span.

Existing seat vibroshock roller, simply simple cylindrical plastic construction, not using inboard bearing With reference to the structure of outside plastic wraps, so being also short of at the aspect such as comfortableness and service life.

Utility model content

The purpose of this utility model is to provide a kind of bearing roller of seat damper.

What the purpose of this utility model was realized in：

Roller and rolling between the bearing roller of seat damper, including the inside and outside circle of bearing inner race, bearing outer ring, bearing The roller back-up ring of sub- one end, is set with annular rolling ring, one end suit of bearing inner race on the external cylindrical surface of described bearing outer ring There is side cover plate.

The concrete structure of annular rolling ring is set with the external cylindrical surface of above-mentioned bearing outer ring is：The side of bearing outer ring sets The annular protrusion for inwardly stretching out of spacing roller is equipped with, the inner surface of the opposite side of bearing outer ring expands on the thin-walled platform that neck is formed pacifies Equipped with roller back-up ring, the width of thin-walled platform is more than the width of roller back-up ring, and the in-flanges that one end of annular rolling ring is arranged is connected to On the outer face of bearing outer ring, the other end U-shaped hook that inwardly twice flange is formed of annular rolling ring is connected to outside roller back-up ring On thin-walled platform.

One end of above-mentioned bearing inner race is set with the concrete structure of side cover plate：On one end external cylindrical surface of bearing inner race Cannelure is provided with, the outer of circular side cover plate is connected on the cannelure of bearing inner race to the U-shaped card hook that end face is arranged.

Above-mentioned U-shaped card is hooked on side cover plate and is circumferentially arranged at intervals with four, and the angle of each U-shaped card hook is 40-50 arcs Degree.

The angle of above-mentioned U-shaped card hook is 45 radians.

Above-mentioned roller is needle roller or roller.

Above-mentioned roller back-up ring, annular rolling ring, side cover plate are with made by plastic material.

This utility model is prominent and beneficial compared to existing technology to be had the technical effect that：

This utility model uses roller bearing so that the rotation of roller is flexible, noise is low, life-span reliability；In roller bearing Bearing outer ring external cylindrical surface on be set with plastics annular rolling ring, frictional force of the annular rolling ring on slide rail is little, noise is little, resistance to Mill property is good, and this utility model is combined using both roller bearing and annular rolling ring so that the unitary rotation of product is flexible, noise Low, long service life, realizes that seat damper smoothly can be rotated freely in any travel position.
