Abstract
The utility model relates to a spline connecting structure for a servo motor. The spline connecting structure comprises an external spline rotating shaft (1), an internal spline shaft sleeve (7) and a motor rotating shaft (10), wherein the external spline rotating shaft (1) and the motor rotating shaft (10) are opposite to each other, and are arranged on the same axis; the spline end of the external spline rotating shaft (1) and the spline end of the motor rotating shaft (10) respectively stretch out from two ends of the internal spline shaft sleeve (7), and are engaged with a spline groove in the internal spline shaft sleeve (7); the peripheral outer side of the internal spline shaft sleeve (7) is connected with a front flange (2) in a way of being in sheathing connection with a bearing (5); one side of the bearing (5) is provided with a bearing gland (6); the bearing gland (6) and the front flange (2) are fixed by a screw. According to the spline connecting structure, as an external spline structure of the servo motor rotating shaft is adopted, the processing difficulty of the servo motor rotating shaft which adopted an internal spline structure in the past is solved; therefore the service life of the motor is prolonged.
Description
Technical field
The utility model relates to actuating motor field, particularly relates to a kind of spline joint structure for actuating motor.
Background technique
Actuating motor has been widely used at machine industry with its advantage such as efficient, energy-conservation, and spline joint is exactly the important Placement of one between actuating motor and injection machine oil pump.What extensively adopt in the market is actuating motor rotating shaft internal spline structure, is used in combination this scheme with the male splined shaft of oil pump.But the difficulty of processing of internal spline rotating shaft is larger, cause spline size and the accuracy of form and position lower, tooth face hardness is also relatively low, and the operating conditions of electric motor of injection machine is often more severe, usually there is overload phenomenon, so there will be the internal spline of actuating motor rotating shaft by the situation of heavy wear, so just greatly reduced the working life of motor.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of spline joint structure for actuating motor, adopt the external splines structure of actuating motor rotating shaft, overcome a processing difficult problem for the actuating motor rotating shaft of original employing internal spline structure, the life-span of having improved motor.
The utility model solves the technological scheme that its technical problem adopts: a kind of spline joint structure for actuating motor is provided, comprise external splines rotating shaft, internal splined shaft bushing and machine shaft, described external splines rotating shaft is relative with machine shaft and be arranged on same axis, both splined end stretch into from the two ends of internal splined shaft bushing respectively and are meshed with the spline of internal splined shaft bushing inside, described internal splined shaft bushing week is connected with forward flange by socket bearing laterally, one side of described bearing is provided with bearing gland, described bearing gland and forward flange are screwed.
Be socketed with laterally the inner Sealed casing pipe with O RunddichtringO the week of described machine shaft.
Gap on described forward flange and between external splines rotating shaft has oilhole.
Between one side, internal splined shaft bushing and the forward flange of described bearing, be furnished with end ring.
The week of described end ring is socketed with lip-type packing laterally.
beneficial effect
The utility model relates to a kind of spline joint structure for actuating motor, adopts the external splines structure of actuating motor rotating shaft, has overcome a processing difficult problem for the actuating motor rotating shaft of original employing internal spline structure, the life-span of having improved motor.
