Abstract
The utility model discloses a sealing structure of a motor casing. The sealing structure comprises a base and an end cover. A shaft hole is arranged on the end cover, wherein a rotating shaft extends out from the shaft hole. A bearing is arranged in the shaft hole. A bearing inner cover and a bearing outer cover are respectively arranged on both sides of the bearing. The base and the end cover are in stopper fit. The stopper fit position of the base and the end cover is sealed by a sealing ring and a sealant. The bearing outer cover and the end cover are in stopper fit. The stopper fit position of the bearing outer cover and the end cover is sealed by a sealing ring and a sealant. According to the sealing structure of the motor casing, the sealing rings are additionally arranged at the stopper fit position of the base and the end cover and the stopper fit position of the bearing outer cover and the end cover, thus the sealing performance is enhanced and the waterproof performance is improved; and the sealing structure can effectively prevent water from coming into the motor casing, and has the advantages of simple structure and easy realization.
Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of hermetically-sealed construction of motor case.
Background technology
Motor, is commonly called as motor, refers to a kind of calutron of realizing electric energy conversion or transmit according to the law of electromagnetic induction.Casing is one of important component part of motor.As shown in Figure 1, structural representation for existing motor case, it is by support 11, end cap 12 forms, support 11 is coated with sealant sealing with the plane matching part of end cap 12, on end cap 12, have axis hole, in axis hole, be provided with bearing, rotating shaft 15 is through this axis hole, the both sides of bearing are provided with the internal bearing cover 14 being connected with end cap 12, bearing end cover 13, bearing end cover 13 is coated with sealant sealing with the plane mating part of end cap 12, the sealing property of this kind of casing is poor, water resistance is low, water easily enters in casing, cause motor winding to make moist, and then cause winding inter-turn or phase fault, winding even, thereby affect the normal operation of production line.
Utility model content
The purpose of this utility model is for the problems referred to above, and a kind of hermetically-sealed construction of motor case is provided, poor to solve the sealing of existing motor case, the problem that water resistance is low.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of hermetically-sealed construction of motor case, comprise support, end cap, on described end cap, have the axis hole that can make rotating shaft stretch out, bearing is installed in axis hole, the both sides of described bearing are separately installed with internal bearing cover, bearing end cover, and described support adopts seam to coordinate with end cap, and the seam cooperation place of support and end cap adopts sealing ring, sealant sealing, described bearing end cover adopts seam to coordinate with end cap, and the seam cooperation place of bearing end cover and end cap adopts sealing ring, sealant sealing.
Further, described sealing ring is O RunddichtringO.
The beneficial effects of the utility model are, the hermetically-sealed construction of described a kind of motor case is set up sealing ring by the seam cooperation place of seam cooperation place, end cap and bearing end cover at end cap and support, thereby strengthened its sealing property, improved its water resistance, can effectively avoid water to enter in casing, simple in structure, be easy to realize.
