Abstract
The utility model relates to a kind of speed reducer axial end cap, comprise end cap body, described end cap body evenly offers multiple tapped hole along its circumferencial direction, axis hole is offered in the axial direction in the centre of end cap body, described end cap body also offers radial location hole, in described radial location hole, positioning screwn is installed, the inwall of described axis hole is bonded with elastic wear-resisting layer by adhesive-layer, the thickness of described elastic wear-resisting layer is 2mm, and the described edge at axis hole is provided with chamfering.The utility model structure is simple, reasonable in design, by being provided with elastic wear-resisting layer, decreasing the wearing and tearing of axle, having good elasticity, significantly reduces the wearing and tearing that rotating shaft high speed rotating causes the direct intense impact of end cap shaft hole inner wall, improves working life.
Description
Technical field
The utility model relates to speed reducer part field, particularly relates to a kind of speed reducer axial end cap.
Background technique
Speed reducer is generally used for the transmission device of low rotation speed large torque, motor, internal-combustion engine or other power run up are reached the object of deceleration by the gearwheel on the few gears meshing output shaft of the number of teeth on the input shaft of speed reducer, common speed reducer also has and severally reaches desirable slowing effect to same principle gear.The effect of speed reducer is: improve output torque while of reduction of speed, and moment of torsion export ratio exports by motor and takes advantage of reduction speed ratio, but will note exceeding speed reducer rated torque; Slow down and reduce the inertia of load simultaneously, inertia be reduced to reduction speed ratio square.Speed reducer of a great variety, model is different, and variety classes has different purposes.Retarder of a great variety, can be divided into gear reducer, worm reducer and plane table thermoconductivity meter according to actuation types; Single-stage and multi-stage speed reducer can be divided into according to transmission progression difference; Cylinder gear speed reducer, cone gear reducer and circular cone-cylinder gear speed reducer can be divided into according to gear shape; Expansion, flow deviding type and coaxial-type retarder can be divided into again according to the setting type of transmission.Axle on speed reducer is that axially end cap is stretched, but axle is in rotary course at a high speed, can produce collision, add the wearing and tearing of axle, can produce circular runout under serious conditions, affect the use of speed reducer output shaft between the axis hole on its outer surface and end cap.
Summary of the invention
The utility model, in order to overcome deficiency of the prior art, provides a kind of speed reducer axial end cap, is convenient to install.
The utility model is achieved through the following technical solutions:
A kind of speed reducer axial end cap, comprise end cap body, described end cap body evenly offers multiple tapped hole along its circumferencial direction, axis hole is offered in the axial direction in the centre of end cap body, described end cap body also offers radial location hole, in described radial location hole, positioning screwn is installed, the inwall of described axis hole is bonded with elastic wear-resisting layer by adhesive-layer.
As optimal technical scheme of the present utility model, the described edge at axis hole is provided with chamfering, and the model of described chamfering is 2mm × 45 °.
As optimal technical scheme of the present utility model, described elastic wear-resisting layer is urethane material.
As optimal technical scheme of the present utility model, the thickness of described elastic wear-resisting layer is 2mm.
As optimal technical scheme of the present utility model, the quantity of described tapped hole is 14, is evenly distributed on end cap body.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, by being provided with elastic wear-resisting layer, decrease the wearing and tearing of axle, there is good elasticity, significantly reduce the wearing and tearing that rotating shaft high speed rotating causes the direct intense impact of end cap shaft hole inner wall, improve working life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-end cap body; 2-tapped hole; 3-axis hole; 4-chamfering; 5-elastic wear-resisting layer; 6-radial location hole; 7-positioning screwn.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of speed reducer axial end cap, comprise end cap body 1, described end cap body 1 evenly offers multiple tapped hole 2 along its circumferencial direction, axis hole 3 is offered in the axial direction in the centre of end cap body 1, described end cap body 1 also offers radial location hole 6, in described radial location hole 6, positioning screwn 7 is installed, the inwall of described axis hole 3 is bonded with elastic wear-resisting layer 5 by adhesive-layer.By being provided with elastic wear-resisting layer 5, decrease the wearing and tearing of axle, there is good elasticity, significantly reduce the wearing and tearing that rotating shaft high speed rotating causes the direct intense impact of end cap shaft hole inner wall, improve working life.
The described edge at axis hole 3 is provided with chamfering 4, and the model of described chamfering 4 is 2mm × 45 °.
Described elastic wear-resisting layer 5 is urethane material, polyurethane full name is polyurethane, it is the general designation of the macromolecular compound containing repetition carbamate groups on main chain, it is formed by organic diisocyanate or polyisocyanates and dihydroxy or polyol addition polymerization, and the thickness of described elastic wear-resisting layer 5 is 2mm.
Preferably, the quantity of described tapped hole 2 is 14, is evenly distributed on end cap body 1.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
