Abstract
The utility model discloses a shaft double-seal structure for a motor. The shaft double-seal structure comprises a bearing, a rotation shaft, an end cover, a frame oil seal and a seal piece. The bearing and the rotation shaft are interference fit. The frame oil seal and the bearing are cooperated and sleeve the rotation shaft. The side face of the end cover is provided with a groove. The seal piece is a hollow ring structure and is installed at the shaft head of the rotation shaft. The seal piece comprises a seal piece lip mouth, a metal shell and a shaft hole. The shaft hole and the rotation shaft are in close cooperation. The seal piece lip mouth and the end cover are in close cooperation. The metal shell is placed in the groove of the end cover, and the metal shell and the end cover are in clamp connection. According to the shaft double-seal structure, a seal problem of a stainless steel motor is solved, on the basis of a common frame oil seal, the seal piece is added at the shaft head and the end cover and is close to the end cover, the gap of the connection part of the end cover and the rotation shaft are sealed, thus double seal is formed, and outside materials of water, oil and dust are effectively blocked.
Description
Technical field
The utility model relates to a kind of hermetically-sealed construction, particularly relates to a kind of axle double sealing structure for motor.
Background technology
All need the degree of protection of IP69K for the motor of food machinery, after use, conventionally need to rinse motor with hot water more than 80 degree, because existing single skeleton oil seal can not meet higher requirement, be technological difficulties for the sealing of axle head always.
Summary of the invention
The utility model, in order to overcome the deficiency of above-mentioned technical problem, provides a kind of axle double sealing structure for motor, can address the above problem completely.
The technical scheme solving the problems of the technologies described above is as follows:
For the axle double sealing structure of motor, comprise bearing, rotating shaft, end cap, outside framework oil seal and seal, described bearing and rotating shaft interference fit, described outside framework oil seal and bearing fit are socketed in described rotating shaft, the side of described end cap arranges groove, described seal is hollow ring structure, seal is arranged on rotating shaft spindle nose place, described seal comprises seal lip, metal shell and axis hole, described axis hole and described rotating shaft closely cooperate, described seal lip and end cap closely cooperate, described metal shell is positioned in the groove of end cap and end cap clamping.
The utility model has solved the sealing problem on stainless steel motor, it is on the basis of common skeleton oil seal, increase again a seal at spindle nose and end caps, be close to end cap, by the gap sealing of end cap and rotating shaft junction, thereby composition double-layer seal effectively stops extraneous water, dirt and wet goods material, utilize contact and centrifugal action to play sealing function, ensured the internal environment that motor safety is clean.Sealing structure can be used on the stainless steel motor of medical treatment, food processing and beverage industry with its high IP grade.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is installation diagram of the present utility model;
Fig. 2 is the structural representation of seal;
Fig. 3 is the side schematic view of seal;
In figure: 1 is bearing, 2 is rotating shaft, and 3 is end cap, and 4 is outside framework oil seal, and 5 is seal, and 6 is groove, and 7 is seal lip, and 8 is metal shell, and 9 is axis hole.
Embodiment
For the axle double sealing structure of motor, comprise bearing 1, rotating shaft 2, end cap 3, outside framework oil seal 4 and seal 5, described bearing 1 and rotating shaft 2 interference fit, described outside framework oil seal 4 is connected in described rotating shaft 2 with bearing 1 engage sleeves, the side of described end cap 3 arranges groove 6, described seal 5 is hollow ring structure, seal 5 is arranged on rotating shaft 2 spindle nose places, described seal 5 comprises seal lip 7, metal shell 8 and axis hole 9, described axis hole 9 closely cooperates with described rotating shaft 2, described seal lip 7 closely cooperates with end cap 3, described metal shell 8 is positioned in the groove 6 of end cap and end cap 3 clampings.
The utility model has solved the sealing problem on stainless steel motor, it is on the basis of common skeleton oil seal, increase again a seal at spindle nose and end caps, be close to end cap, by the gap sealing of end cap and rotating shaft junction, thereby composition double-layer seal effectively stops extraneous water, dirt and wet goods material, utilize contact and centrifugal action to play sealing function, ensured the internal environment that motor safety is clean.Sealing structure can be used on the stainless steel motor of medical treatment, food processing and beverage industry with its high IP grade.
