Abstract
The utility model relates to the field of motors, and in particular relates to a connection structure of a motor end cover and a damping rubber ring. The connection structure comprises the motor end cover and the damping rubber ring. The middle part of the axial end face of the motor end cover is convex outward to form a convex cavity which is used for accommodating a bearing. The damping rubber ring sleeves the outer surface of the convex cavity. A connecting hole is arranged on the motor end cover beside the convex cavity. A convex column which matches the connecting hole in a clamping manner is arranged on the end face of the damping rubber ring. The convex cavity is a bearing chamber which is used for accommodating the bearing. The convex column is clamped in the connecting hole, thus the damping rubber ring and the motor end cover are reliably connected. Even if a steel ring is not built in the damping rubber ring, the demand of a pulling-out force can be met. According to the structure, the damping rubber ring and the end cover are elastically connected, which can effectively prevent the deformation of the bearing chamber.
Description
Technical field
The utility model relates to machine field, particularly the syndeton of electric motor end cap and damping cushion rubber.
Background technology
Motor need increase rubber shock-absorbing cushion rubber in the time of assembling between electric motor end cap bearing chamber and electric machine casing, and this damping cushion rubber act as and reduces vibrations and the noise that motor produces in the time of operation.Because the damping cushion rubber without steel ring cannot reach the desired pulling-out force of motor, so conventionally adopt built-in steel ring structure to increase the adhesion of damping cushion rubber and electric motor end cap casing, prevent that damping cushion rubber from coming off from end cap, but due to the existence of steel ring, the elasticity of damping cushion rubber is little, working pressure machine is by strong damping cushion rubber being inserted on bearing with end cover chamber manually, this strong extruding mounting means very easily causes the distortion of end cap upper bearing (metal) chamber, thereby cause motor bearings noise bad, or motor can not start flexibly.
Summary of the invention
The purpose of this utility model is to provide a kind of syndeton that connects reliable electric motor end cap and damping cushion rubber.
For achieving the above object, the utility model has adopted following technical scheme: the syndeton of a kind of electric motor end cap and damping cushion rubber, comprise electric motor end cap and damping cushion rubber, the axial end middle part of electric motor end cap convexes to form the protruding chamber for holding bearing toward the outer side, described damping rubber snare is located on the outer surface in protruding chamber, the electric motor end cap of described protruding chamber side is provided with connecting hole, and the end face of described damping cushion rubber is provided with connecting hole and forms the projection that clamping coordinates.
Owing to adopting above technical scheme, protruding chamber is the bearing chamber for holding bearing, projection is connected in connecting hole, just can realize between damping cushion rubber and electric motor end cap and reliably connecting, even if damping cushion rubber does not have built-in steel ring can meet the demand of pulling-out force yet, the elasticity that is connected between damping cushion rubber and the end cap of this structure is connected, and can effectively prevent the distortion of bearing chamber.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of electric motor end cap;
Fig. 3 is the structural representation of damping cushion rubber.
Embodiment
As shown in Figure 1, the syndeton of a kind of electric motor end cap and damping cushion rubber, comprise electric motor end cap 10 and damping cushion rubber 20, axial end 13 middle parts of electric motor end cap 10 convex to form the protruding chamber 11 for holding bearing toward the outer side, described damping cushion rubber 20 is set on the outer surface in protruding chamber 11, the electric motor end cap 10 of described protruding chamber 11 sides is provided with connecting hole 12, and the end face of described damping cushion rubber 20 is provided with connecting hole 12 and forms the projection 21 that clamping coordinates.
Protruding chamber 11 is the bearing chamber for holding bearing, and projection 21 is connected in connecting hole 12, because projection 21 is rubber structures, has certain elasticity, as long as size is coincide, is just difficult to spin off in connecting hole 12 once snap fit onto the interior base of connecting hole 12.The connected mode of this clamping has realized the reliable connection of damping cushion rubber 20 and electric motor end cap 10, therefore the damping cushion rubber 20 of this structure is without the damping cushion rubber that adopts built-in steel ring, economization production cost, lower installation difficulty, effectively avoid causing due to installation damping cushion rubber 20 distortion of bearing chamber, lowered motor bearings noise simultaneously.
Described electric motor end cap 10 is peviform and its basin edge is bent to form flange toward the outer side, the basin bottom part of electric motor end cap 10 is axial end 13, this axial end 13 is provided with towards the annular recess 14 away from axial end 13 1 side depressions, and the region between described annular recess 14 and electric motor end cap 10 center forms protruding chamber 11.
The bottom surface of described annular recess 14 is plane, and described connecting hole 12 is positioned at the bottom surface of annular recess 14.As shown in Fig. 2 or 3, annular annular recess 14 is for holding damping cushion rubber 20, and this structure can be saved space, can ensure that the bottom in protruding chamber 11 and the end face of electric motor end cap 10 are positioned at agreement plane simultaneously.When installation, projection 21 is aimed at connecting hole 12, then a little firmly pushes just Snap joint hole 12 firmly of projection 21, install very simple, economize, efficiency is higher.
Described projection 21 is evenly arranged at intervals with four along the circumferencial direction of damping cushion rubber 20, and the position of described connecting hole 12 and quantity are all coincide with projection 21.The quantity of projection 21 can be made corresponding variation according to the size of electric motor end cap 10, and the dispersed formula of projection 21 arranges that to make damping cushion rubber 20 stressed evenly, avoids stressed and concentrates.Projection 21 and the connecting hole 12 of four groups of mutual clamping cooperations make the connection of damping cushion rubber 20 and electric motor end cap 10 more reliable, can effectively prevent coming off of damping cushion rubber 20.
