Abstract
The utility model discloses a such spline connection spare structure, the structure that exists for solving spline connection structure is comparatively complicated, and especially this structure is arranged the bolt head of retaining member in the axle spline downthehole, is difficult for adjusting retaining member scheduling problem, the utility model discloses take one end is provided with external splines (4) on axis body (1), and the other end is provided with breach (2) on axis body (1), is provided with slot (5) along radial direction in axis body (1) one side that is close to breach (2) to make slot (5) link up with internal spline (3) hole, install the retaining member in breach (2) for adjustment slot (5) width.
Description
Technical Field
The utility model relates to a transmission connecting piece structure especially relates to a spline connection piece structure of constituteing by axis body, internal spline and external spline.
Background
Chinese patent CN208935191U discloses such a spline connection structure, which has the structural characteristics that: including the integral key shaft that has the axle splined hole, the one end in axle splined hole is provided with connecting sleeve group, connecting sleeve group includes the adapter sleeve, alternate tight cover that expands on the adapter sleeve and be used for locking the adapter sleeve and the retaining member of tight cover that expands, the lateral surface of adapter sleeve is provided with the first external spline section of axle splined hole complex, and the medial surface of adapter sleeve is provided with interior taper hole, the lateral surface of tight cover that expands be provided with interior taper hole complex external conical surface, and the medial surface of tight cover that expands is provided with the internal spline section. Therefore, the structure is complicated, and especially, the structure places the bolt head of the locking member in the shaft spline hole, so that the locking member is not easy to adjust.
Disclosure of Invention
The utility model aims at providing a simple structure adjusts the spline connection spare structure of retaining member simultaneously easily.
In order to achieve the above object, the utility model relates to a spline connection spare structure comprises axis body, internal spline and external spline, is provided with the external spline on the axis body, is provided with the internal spline on the axis body hole one end is provided with the external spline on the axis body, and the other end is provided with the breach on the axis body, is provided with the slot along radial direction in axis body one side near the breach to make slot and internal spline hole link up, install the retaining member in the breach for adjust the slot width.
The notch is arranged to have an L-shaped radial section, and at least two through holes convenient for the locking piece to pass through are arranged on the notch adjacent to the groove.
The central line of the groove is parallel to the axis of the shaft body, and at least two screw holes which can be in threaded connection with the locking piece are arranged on the side surface of the groove corresponding to the through hole on the notch.
After the structure is adopted, because the external spline is arranged at one end of the shaft body, the notch is arranged at the other end of the shaft body, the groove is arranged at one side of the shaft body close to the notch along the radial direction and is communicated with the internal spline hole, and the locking piece is arranged in the notch and is used for adjusting the width of the groove. Thereby achieving the purposes of simple structure and easy adjustment of the locking piece.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is a schematic perspective view of a spline connection member structure of the present invention.
In the figure: 1. the shaft body 2, the gap 3, the internal spline 4, the external spline 5 and the groove.
Detailed Description
Fig. 1 shows a spline connection member structure of the present invention, which comprises a shaft body 1, an internal spline 3 and an external spline 4, wherein the shaft body 1 is provided with the external spline 4, the inner hole of the shaft body 1 is provided with the internal spline 3, one end of the shaft body 1 is provided with the external spline 4, the other end of the shaft body 1 is provided with a notch 2, one side of the shaft body 1 near the notch 2 is provided with a groove 5 along the radial direction, and the groove 5 is communicated with the hole of the internal spline 3, and a locking member is installed in the notch 2 for adjusting the width of the groove 5; the notch 2 is arranged to have an L-shaped radial section, at least two through holes convenient for the locking piece to pass through are arranged on the notch 2 adjacent to the groove 5, and the locking piece is a bolt; the central line of the groove 5 is parallel to the axis of the shaft body 1, and at least two screw holes which can be in threaded connection with the locking piece are arranged on the side surface of the groove 5 corresponding to the through hole on the notch 2, namely the shaft body 1.
