Abstract
The utility model relates to a direct connection motor of an electric hoist. The direct connection motor is high in coaxial precision, smooth and stable in operation and low in noises after assembling, and comprises a motor and the electric hoist. The axial surface of an output shaft of the motor is a spline groove, the connection part of a reducer shaft in the electric hoist is a spline shaft sleeve, and the spline shaft sleeve is matched with the output shaft of the spline groove in the motor in an inserted manner. The direct connection motor has the advantages that assembling and connection of the motor and the electric hoist is quick, simple and convenient, the direct connection motor is high in coaxial precision and low in noises after assembling, and the motor in operation is large in output torque and smooth and stable.
Description
Technical field
The utility model relate to a kind of not only install after coaxial precision high, and the direct-connected motor of electric block steady, that noise is little during operation, belong to field of motor manufacturing.
Background technology
CN201074169Y, title " rear-actuating electric hoist ", it comprises an electric block, the motor of this electric block and retarder are arranged on the same end of reel, motor shaft is connected with retarder one axle by coupler, the other end of retarder one axle is rotatably installed in the hollow shaft of reel, the other end of reel is rotatably installed on barrel cover, and the gear on retarder two axles is engaged on the gear of hollow shaft.Shortcoming: this electric block and motor are realized shaft coupling by coupler, and the coaxial precision of diaxon is low, during operation steadily and noise large.
The utility model content
Design goal: for avoiding the deficiency in background technology, design a kind of not only install after coaxial precision high, and the direct-connected motor of electric block steady, that noise is little during operation.
Design plan: for realizing above-mentioned design goal.1, the output shaft axial plane of motor is spline, and the connecting portion of the reducer shaft in electric block is hub splines, and the design that this hub splines is pegged graft and coordinated with spline output shaft in motor, be one of technical characterictic of the present utility model.The purpose of design is like this: it is large that the spline motor output shaft has output torque, the characteristics such as output speed is steady, electric block adopts the spline spindle motor to drive, effectively improve the work efficiency of electric block, hub splines is pegged graft and is coordinated with spline output shaft in motor, has not only improved both right alignmenies after the connection, and directly has been connected because motor and retarder do not need coupler, both connect quick, convenient, and while moving, noise is also little simultaneously.2, the motor case bottom is provided with footing, and the design that this footing is foot-detachable, be two of technical characterictic of the present utility model.The purpose of design is like this: the one, and the user can dismantle motor foot according to actual needs, improves the use alerting ability of electric motor for pump; The 2nd, the dismounting horizontal support of motor foot and vertical support can be general, reduce the cost of development that support is touched tool.
Technical scheme: the direct-connected motor of a kind of electric block, comprise motor and electric block, the output shaft axial plane of described motor is spline, and the connecting portion of the reducer shaft in electric block is hub splines, and this hub splines is pegged graft and is coordinated with spline output shaft in motor.
The utility model is compared with background technology, and the one, motor is connected fast and convenient with the electric block installation, and after installing, coaxial precision is high, and noise is little; The 2nd, after the motor operation, output torque is large and steady.
The accompanying drawing explanation
Fig. 1 is the structural representation of the direct-connected motor of electric block.
Fig. 2 is the output shaft cross-sectional view of the direct-connected motor of electric block.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1, Fig. 2.The direct-connected motor of a kind of electric block, comprise motor 1 and electric block, and the output shaft axial plane of described motor 1 is spline 11, and the connecting portion of the reducer shaft in electric block is hub splines, and this hub splines is pegged graft and coordinated with 11 output shafts of spline in motor 1.Both the spline of the connecting portion of spline 11 by the output shaft axial plane of motor 1 and reducer shaft was pegged graft to coordinate and was connected with retarder, and the spline size in 11 sizes of the spline in output shaft and reducer shaft is complementary.Described motor 1 bottom of shell is provided with footing 2, and this footing 2 is foot-detachable.
Need to understand: although above-described embodiment is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing, all fall in protection domain of the present utility model.
