Abstract
The utility model relates to a high-protection grade three-phase asynchronous motor for a roller bed, which comprises a frame, a stator, a rotor, a shaft, a junction box cover, a junction box base, a front end cover and a rear end cover, wherein the front end cover and the rear end cover are mounted on the frame. The high-protection grade three-phase asynchronous motor is characterized in that the seam allowances of the front and the end covers, and the frame are both provided with seal rings and coated with liquid sealant; and a rubber oil seal is mounted at the site where the shaft is communicated with the front end cover through a shaft hole on the inner side of the front end cover, rubber seal gaskets are respectively arranged at the wire outlet of the rear end cover and the junction box, and the junction box cover and the junction box base adopts a seam allowance structure. The utility model has the advantages as follows: the protection grade and the operation reliability of the motor are improved, and water drops are prevented from entering the inner cavity of the motor so as to prolong the service life of the oil seal and the motor. The utility model is especially suitable for waterish and moist environment of various steel mills.
Description
Technical field
The utility model belongs to the motor manufacturing technology field, particularly relates to a kind of roller-way high-protection level threephase asynchronous that is used in many water of steel mill and the wet environment.
Background technology
At present, the roller-way threephase asynchronous of using in the steel mill, a lot of operating modes have the cooling water splash to motor, and motor product exists following deficiency in the prior art: one, the mating surface place of electric machine stand and end cap does not have the O RunddichtringO, so its degree of protection is poor.Its two, the axle cross the parts that similar oil sealing is not installed in axis hole perforation place with front end housing, cause the motor seal poor performance.Its three, the motor outlet direction is seen as left outlet from shaft extension, and is near apart from the water source, and do not have sealing gasket, the water that splashes easily enters motor internal.Therefore cause above-mentioned electric machines for roller can't satisfy the needs of applying working condition, and then the problem that the motor water inlet is burnt occurs, in order to overcome above-mentioned defective, the inventor has developed a kind of roller-way threephase asynchronous of high-protection level.
Summary of the invention
The utility model provides a kind of high-protection level threephase asynchronous of the roller-way in many water, the wet environment in the steel mill that is applicable to for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: roller-way high-protection level threephase asynchronous, comprise support, stator, rotor, axle, connector cover, junction box seat and front end housing, the rear end cap installed with support, it is characterized in that: described front end housing, rear end cap and support stop portion all are equipped with sealing ring, and are coated with one deck liquid sealant; Axle and front end housing are crossed axis hole and are connected and to be in the end cap installed inside rubber oil sea is arranged, and place's outlet of described rear end cap and terminal box place are provided with rubber gasket respectively, and described connector cover and junction box seat are the seam fit structure.
The utility model can also adopt following technical scheme:
Described front end housing, rear end cap and support stop portion all are equipped with the O RunddichtringO.
Axle and front end housing are crossed axis hole and are connected and to be in the end cap installed inside rubber oil seal with reinforce is arranged.
Place's outlet of described rear end cap and terminal box place are provided with the rubber gasket of heat resistant rubber material respectively.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, promptly by the O RunddichtringO being housed at front end housing, rear end cap and support stop portion, be coated with liquid fluid sealant one deck during assembling, can improve the sealing effectiveness at seam mating surface place; By crossing axis hole perforation place installation rubber oil seal with reinforce at axle and front end housing, improved the barrier propterty of motor, and oil sealing is installed in the end cap inboard, can reduces of the corrosion of the water of splash again oil sealing, prolong the useful life of oil sealing, and then improved the operational reliability of motor; Connection box for motor is located at the rear end cap place, away from the water source, and install the rubber gasket of heat resistant rubber material additional at junction box seat and support, junction box seat and connector cover contact-making surface place, connector cover cooperates with the junction box seat seam, can prevent that also water droplet from entering motor cavity, prolong the useful life of motor.Therefore the electric machines for roller degree of protection through particular design improves, and operational reliability increases, and is particularly suited for using in the environment of each big Duo Shui of steel mill, humidity.
