Abstract
The utility model discloses a motor shaft draw bail, including the motor to and with motor connection's oil pump, be provided with the motor shaft on the motor, be provided with the pump shaft on the oil pump, motor shaft and pump shaft end are provided with the axle head spline respectively, motor shaft and pump shaft are provided with involute spline's ring gear connection through an integrated into one piece. The utility model discloses an integrated into one piece is provided with involute spline's ring gear connection motor shaft and pump shaft, can shorten the length of motor shaft and oil pump shaft, reduces the axial deviation of motor and oil pump, simultaneously, through changing the fit clearance between involute spline shaft coupling and motor shaft and the oil pump shaft, still have certain axial, angle, radial compensation ability. The current plum blossom shaft coupling of contrast, the utility model discloses an all functions of plum blossom shaft coupling can be realized to the ring gear, have still that the processing cost is low, a simple to operate, advantage that the precision is high.
Description
Technical field
This utility model relates to machine field, is specifically related to motor shaft draw bail.
Background technology
Traditional connected mode between injection machine oil pump shaft and motor shaft is to use plum coupling, and plum coupling is made up of two half a couplers, and processing cost is high, installs trouble, and precision is low.
Utility model content
The purpose of this utility model is to provide a kind of New-type electric machine shaft coupling structure, reduces processing cost, improves the precision that motor shaft couples with pump shaft.
This utility model be the technical scheme is that
Motor shaft draw bail, including motor, and the oil pump coupled with motor, it is provided with motor shaft on described motor, it is provided with pump shaft on described oil pump, described motor shaft and pump shaft end are respectively arranged with axle head spline, described motor shaft and pump shaft and are connected by an one-body molded ring gear being provided with involute spline.
As the further improvement of technique scheme, being provided with bracket between described motor and oil pump, described bracket two ends connect motor and oil pump respectively.
The beneficial effects of the utility model are:
This utility model uses an one-body molded ring gear being provided with involute spline to connect motor shaft and pump shaft, can shorten the length of motor shaft and oil pump shaft, reduce the axial deviation of motor and oil pump；Meanwhile, by changing the fit clearance between involute spline coupling joint and motor shaft and oil pump shaft, also there is certain axial, angular, compensation ability of radial direction.Contrasting existing plum coupling, ring gear of the present utility model can realize all functions of plum coupling, also has the advantage that processing cost is low, easy for installation, precision is high.
Accompanying drawing explanation
With embodiment, this utility model is further detailed below in conjunction with the accompanying drawings.
Fig. 1 is motor shaft draw bail exploded perspective view of the present utility model.
Fig. 2 is the structural representation of ring gear.
Fig. 3 is the structural representation after motor is connected with oil pump.
Detailed description of the invention
With reference to Fig. 1, this utility model provides the exploded perspective view of a kind of motor shaft draw bail, including motor 1, and the oil pump 2 coupled with motor 1, it is provided with motor shaft 11 on described motor 1, it is provided with pump shaft 21 on described oil pump 2, motor shaft 11 and pump shaft 21 end are respectively arranged with axle head spline, described axle head spline is involute spline, motor shaft 11 and pump shaft 21 are connected by an one-body molded ring gear 3 being provided with involute spline, as in figure 2 it is shown, the size of described ring gear 3 determines according to torque to be transmitted with length.Further, with reference to Fig. 3, being additionally provided with bracket 4 between described motor 1 and oil pump 2, bracket 4 two ends connect motor 1 and oil pump 2 respectively, and motor 1 and oil pump 2 can be supported by bracket 4, simultaneously protection ring gear 3 and motor shaft 11, the junction of pump shaft 21.
This utility model uses an one-body molded ring gear 3 being provided with involute spline to connect motor shaft 11 and pump shaft 21, can shorten the length of motor shaft 11 and pump shaft 21, reduces the axial deviation of motor 1 and oil pump 2；Meanwhile, by changing the fit clearance between involute spline coupling joint and motor shaft 11 and pump shaft 21, also there is certain axial, angular, compensation ability of radial direction.Contrasting existing plum coupling, ring gear 3 of the present utility model can realize all functions of plum coupling, also has the advantage that processing cost is low, easy for installation, precision is high.
Above concrete structure and sized data are to be illustrated preferred embodiment of the present utility model, but this utility model is created and is not limited to described embodiment, those of ordinary skill in the art it may also be made that all equivalent variations or replacement on the premise of this utility model spirit, and deformation or the replacement of these equivalents are all contained in the application claim limited range.
