Abstract
The utility model relates to a connecting structure between a motor spindle of an endless rope winch and an input shaft of a speed reducer, which comprises the motor spindle and the input shaft of the speed reducer; a shaft sleeve is sleeved at the outer part between the input shaft of the speed reducer and the motor spindle; a planetary carrier is arranged outside the shaft sleeve, and one end of the planetary carrier is connected with a motor through a flange plate; a bearing is installed outside the planetary carrier; the input shaft of the speed reducer is in transmission connection with the shaft sleeve through a spline; the motor spindle is in transmission connection with the shaft sleeve through a flat key; the flat key is longer than the spindle; and a plastic nylon separation plate positioned in the shaft sleeve is arranged between the motor spindle and the end part of the input shaft of the speed reducer. The connecting structure has the benefits that the design is reasonable, and the structure is simple; under the situation that the connecting strength between the motor spindle and the input shaft of the speed reducer is ensured, the production cost is fully reduced, and the production process is simplified; and the practicability is strong, and the popularization and the application are facilitated.
Description
Technical field
The utility model relates to a kind of mine mechanism, relates in particular to a kind of endless rope winch electric machine main shaft and speed reducer input shaft linkage structure.
Background technique
At present, between the electric machine main shaft of endless rope winch and speed reducer input shaft, be connected by axle sleeve, inner hole of shaft sleeve is axially processed with spline, electric machine main shaft and speed reducer input shaft also need to be processed as spline shaft structure, because the technique of processing spline and splined shaft is comparatively complicated, especially for electric machine main shaft, need to be processed into specially splined shaft, the main shaft of the motor of selling on market is generally single key slot or two keyway, the main shaft that this just need to reprocess splined shaft and replace motor, has so just increased cost of production.
Model utility content
The utility model, in order to solve deficiency of the prior art, provides a kind of linkage structure is simple, cost of production is low endless rope winch electric machine main shaft and speed reducer input shaft linkage structure.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: endless rope winch electric machine main shaft and speed reducer input shaft linkage structure, comprise electric machine main shaft and speed reducer input shaft, outer cover between speed reducer input shaft and electric machine main shaft is provided with axle sleeve, axle sleeve is provided with planet carrier outward, planet carrier one end is connected on motor by flange plate, planet carrier is provided with bearing outward, between described speed reducer input shaft and axle sleeve, be connected by spline drived, between electric machine main shaft and axle sleeve, be in transmission connection by flat key, flat key length is greater than colored key length, between the end of electric machine main shaft and speed reducer input shaft, be provided with the plastic nylon dividing plate that is positioned at axle sleeve.
Between described electric machine main shaft and axle sleeve, be in transmission connection by two symmetrical flat keys.
Adopt technique scheme, due to a side in axle sleeve is arranged to spline, opposite side arranges flat key groove, flat key groove and electric machine main shaft are connected, in the situation that meeting join strength, electric machine main shaft is also offered flat key groove, the processing technology of so just having simplified electric machine main shaft, reduces costs, and the motor that can directly buy on market can connect.Between electric machine main shaft and axle sleeve, be in transmission connection by two symmetrical flat keys, the join strength can improve like this transmitting torque between electric machine main shaft and axle sleeve time.Plastic nylon dividing plate plays the effect that limits when mounted electric machine main shaft and speed reducer main shaft axial position.Flat key length is greater than colored key length, like this can balance sleeve respectively with the join strength of electric machine main shaft and speed reducer input shaft.
The utility model is reasonable in design, simple in structure, in the situation that guaranteeing electric machine main shaft and speed reducer input shaft join strength, fully reduces production costs, and simplifies production technology, practical, is easy to apply.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, endless rope winch electric machine main shaft of the present utility model and speed reducer input shaft linkage structure, comprise electric machine main shaft 1 and speed reducer input shaft 2, outer cover between speed reducer input shaft 2 and electric machine main shaft 1 is provided with axle sleeve 3, the outer planet carrier 4 that is provided with of axle sleeve 3, planet carrier 4 one end are connected on motor 6 by flange plate 5, the outer bearing 7 that is provided with of planet carrier 4, between speed reducer input shaft 2 and axle sleeve 3, be in transmission connection by spline 8, between electric machine main shaft 1 and axle sleeve 3, be in transmission connection by two symmetrical flat keys 9, the length of flat key 9 is greater than the length of spline 8, between the end of electric machine main shaft 1 and speed reducer input shaft 2, be provided with the plastic nylon dividing plate 10 that is positioned at axle sleeve 3.
Due to a side in axle sleeve 3 is arranged to spline, opposite side arranges flat key groove, flat key groove and electric machine main shaft 1 are connected, in the situation that meeting join strength, electric machine main shaft 1 is also offered flat key groove, so just simplify the processing technology of electric machine main shaft 1, reduce costs, and the motor that can directly buy on market can connect.Between electric machine main shaft 1 and axle sleeve 3, be in transmission connection by two symmetrical flat keys 9, the join strength can improve like this transmitting torque between electric machine main shaft 1 and axle sleeve 3 time.Plastic nylon dividing plate 10 plays the effect that limits when mounted electric machine main shaft 1 and speed reducer main shaft 2 axial positions.The length of flat key 9 is greater than the length of spline 8, like this can balance sleeve 3 respectively with the join strength of electric machine main shaft 1 and speed reducer input shaft 2.
