Description

Novel electronic tail-gate spline hollow shaft bearing

Technical Field

The utility model relates to a spline hollow shaft bearing technical field specifically is a novel electronic tail-gate spline hollow shaft bearing.

Background

In the industry at present, the spline pipe and the bearing seat are designed in a split mode: spline pipe, bearing frame. The spline pipe is the structure of excircle internal spline, and the function is as follows: the spline feature limits the internal transmission part, bears the torque of the internal transmission part in the motion process and ensures that the internal transmission part realizes axial reciprocating motion; the manufacturing process of the spline tube usually adopts aluminum alloy extrusion, then injection molding is carried out on the end part, one surface of the end part is a plane, and the other surface is designed with a groove or a boss characteristic to be matched with the bearing seat. The function of the bearing seat is as follows: the bearing seat is internally provided with a groove characteristic which is matched with the bearing, and then the bearing is axially limited through the matching of the C-shaped clamp spring.

The existing bearing seat manufacturing process is to perform machining treatment after zinc alloy is formed by die casting, so that the cost is higher; the bearing and the bearing seat are in interference fit, and the bearing seat is made of zinc alloy, so that the bearing is installed by pressing in an air pressure device, and the pressing-in process is irreversible; the C-shaped clamp spring is pressed into the reserved groove of the bearing seat through the air pressure device, the production reject ratio of the pressing-in process is high, and the pressing-in process is irreversible, so that the bearing seat, the bearing and parts of the previous process are scrapped, and the production cost and the after-sale cost are high.

In order to achieve the above object, the utility model provides a following technical scheme: a novel electric tail gate spline tubular bearing seat comprises a spline tube, a bearing seat is installed at one end of the spline tube, a bearing gasket is installed inside the bearing seat, a bearing is installed at one end, away from the spline tube, of the bearing gasket, a bearing cover is installed at one end, away from the spline tube, of the bearing seat in a clamping mode, the bearing seat is connected with the spline tube in a slurry coating injection molding mode, the bearing gasket and the bearing are sequentially installed inside the bearing seat, the bearing gasket and the bearing are subjected to sealing treatment inside the bearing seat to increase the sealing performance of the bearing gasket and the bearing, the bearing cover is installed on the bearing seat in a clamping mode to form a closed state, so that a C-shaped spring is replaced to limit the axial direction of the bearing, the bearing seat, the bearing and parts of a previous process are not scrapped due to the irreversible press-in procedure, the materials of the bearing seat and the bearing cover are changed from zinc alloy to nylon and fiber, and the bearing seat and the bearing cover can be manually installed, no pressing-in of pneumatic equipment is required.

Preferably, the outer surface of the spline pipe is made of an aluminum alloy material, and the performance of the spline pipe is improved by utilizing the characteristics of the aluminum alloy material.

Preferably, the bearing seat and the bearing cover are both made of nylon and fiber, and the strength and the heat resistance of the bearing seat and the bearing cover are enhanced by the nylon and the fiber.

Preferably, the bearing seat is connected to one end of the spline pipe in a slurry coating and injection molding mode.

Preferably, the spline tube, the bearing seat, the bearing gasket, the bearing and the bearing cover are arranged on the same vertical line.

Preferably, the bearing cover and the bearing seat are matched in shape and correspond in position to each other.

Compared with the prior art, the beneficial effects of the utility model are that:

1. this novel electronic tail-gate spline tubular bearing links together bearing frame through the mode and the spline union coupling that package thick liquid was moulded plastics, just so does not need processing again after the zinc alloy die-casting shaping, has reduced a large amount of costs, changes the material of bearing frame for nylon from the zinc alloy and adds fine, just so does not need the impressing of pneumatic equipment, same interference fit, and the required pressure of bearing installation reduces greatly, but manual installation.

2. This novel electronic tail-gate spline tubular bearing seat, bearing cap block are installed on the bearing frame, need impress the bearing frame preformed groove through air pressure device because of C type jump ring also, so the bearing cap replaces C type jump ring and carries on spacingly to the bearing axial, just can not all need scrapping because of the irreversible bearing frame that leads to of procedure of impressing and bearing and preceding process spare part, and the bearing cap equally can manually be installed, and the installation degree of difficulty reduces, and the defective rate reduces, and the after-sales recoverability improves.
