Abstract
The utility model provides an internal spline sleeve for the crane motor drive with guide function, comprising a guiding steel ball, a pressed nut, a pressed spring, an internal spline sleeve and the like. The utility model is characterized in that the guiding steel ball is installed on the internal spline sleeve. The guiding steel ball is provided with the pressed spring. The pressed spring is fixed through the pressed nut. The device overcomes the defect of the prior art, and the structure is simple. The utility model can reduce the maintenance cost and the workload of the maintenance, and has no impacts for the other performances of the crane drive shaft.
Description
Technical field:
The utility model relate to drive a vehicle a kind of connection set of motor power transmission.
Background technique:
At present, there is obvious defects in the driving electric-motor-driving connection set of maintenance assembling, complex structure, and maintenance cost workload high and maintenance is big, and other performances of driving transmission shaft are seriously influenced.
Summary of the invention:
The purpose of this utility model is to avoid the not enough and a kind of driving electric-motor-driving inner spline housing that has guiding that provides of above-mentioned prior art.
The purpose of this utility model is achieved in that a kind of driving electric-motor-driving inner spline housing that has guiding, form by guiding steel ball, clamping nut, holddown spring, inner spline housing etc., it is characterized in that installing on the inner spline housing guiding steel ball, on the guiding steel ball holddown spring is arranged, holddown spring is fixed by clamping nut.
The axle that has external splines can be by steel ball to the positioning of the tooth of inner spline housing, be implemented in the driving cylinder in the assembling of external splines.
Original inner spline housing has been carried out lengthening and assembled guiding device.
Steel ball in the guiding device can replace with other structures.
The steel ball of its guide sleeve and the tooth of internal spline are on same straight line.
Compared with prior art, this device overcomes the defective of prior art, and is simple in structure, can reduce the workload of maintenance cost and maintenance, and other performances of driving transmission shaft are not influenced.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
1-SDeflector, 2-clamping nut, 3-holddown spring, 4-inner spline housing among the figure
Embodiment:
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
