Description

Anti-reverse shaft coupling

Technical field

This utility model relates to a kind of shaft coupling, a kind of anti-reverse shaft coupling that can transmit unidirectional torque.

Background technology

In commercial production, some are had not allow the device that motor equal power device inverts.Such as by motor-driven oil pump systems, when motor reversal, easily cause oil pump to damage, unnecessary damage is caused to equipment, the biggest trouble is brought to producing, in order to prevent workman from causing motor reversal to make oil pump reversion damage because of operation error, typically take to use on the power transmission shaft between oil pump and motor anti-reverse shaft coupling, the brake holding structure that this type of anti-reverse shaft coupling is mostly the directional overrunning clutch involved great expense and structure is complicated and reliability is the highest, or directly use complicated and expensive electronic circuit anti-reverse mechanism.

Utility model content

Technical problem to be solved in the utility model is to provide and a kind of can reliably prevent reversion, simple in construction, manufacture and easy for installation, the anti-reverse shaft coupling of low cost.

Anti-reverse shaft coupling of the present utility model has two half a couplers, and two half a couplers can axis hole and two sections of installation axles that need to transmit moment of torsion by center be connected respectively；One of them half a coupler is movable half a coupler, described movable half a coupler can be slidably matched with the rotating shaft coordinating the heart installed therein, that is, the rotating shaft relative limit in the circumferential at half a coupler and center can transmit moment of torsion, the most in the axial direction can relative rectilinear slip；Another half a coupler is also movable half a coupler, or for fixing half a coupler, described fixing half a coupler refers to that half a coupler can fixing with the rotating shaft coordinating the heart installed therein be connected；The end face of described half a coupler is divided into two end face parts by one by the partitioning plane in axle center, the two end face part is that a diameter of axial opposed direction being perpendicular to partitioning plane turns over certain angle relatively on locus, thus forms two towards contrary Vertical Meshing face in the described partitioning plane position of the end of a half a coupler；The end of two half a couplers relative to time, two Vertical Meshing face relative engagement two-by-two, it is thus possible to the most spacing and transmit moment of torsion when two half a coupler opposite direction rotatings, simultaneously can two half a couplers are opposing rotate time cannot circumference spacing, but axially mutually push open；The back segment of described movable half a coupler is provided with compression spring, and the spring force of described compression spring makes two half a coupler ends have mutually close trend.

Further, the endoporus of described half a coupler arranges keyway, enable half a coupler to be connected by the rotating shaft of keyway and Jian Yu center and to transmit moment of torsion.

Further, two described half a couplers are movable half a coupler.

Further, two described half a couplers can also is that a movable half a coupler and a fixing half a coupler.

This utility model utilizes special half a coupler end construction, it is possible to reliably unidirectional delivery moment of torsion, and its number of parts is few simultaneously, simple in construction, easy to install, low cost.

Detailed description of the invention

As in figure 2 it is shown, this anti-reverse shaft coupling has two half a couplers 1, two half a couplers can axis hole and two sections of rotating shafts that need to transmit moment of torsion by center be connected respectively；One of them half a coupler is movable half a coupler, described movable half a coupler can be slidably matched with the rotating shaft coordinating the heart installed therein, that is, the rotating shaft relative limit in the circumferential at half a coupler and center can transmit moment of torsion, the most in the axial direction can relative rectilinear slip；Another half a coupler 1 is also movable half a coupler, or for fixing half a coupler, described fixing half a coupler refers to that half a coupler can fixing with the rotating shaft coordinating the heart installed therein be connected.

As shown in Figure 1, the end face of described half a coupler is divided into two end face parts 2 by one by the partitioning plane in axle center, the two end face part 2 is on locus, it it is a diameter of axle being perpendicular to partitioning plane, the most relatively turn over certain angle, thus form two towards contrary Vertical Meshing face 3 in the described partitioning plane position of the end of a half a coupler.

Such as Fig. 2, the end of two half a couplers 1 relative to time, two Vertical Meshing face 3 relative engagement two-by-two such that it is able to the most spacing and transmit moment of torsion when two half a coupler opposite direction rotatings, simultaneously can two half a couplers are opposing rotate time cannot circumference spacing, but axially mutually push open；The back segment of described movable half a coupler is provided with compression spring 4, and the spring force of described compression spring 4 makes two half a coupler ends have mutually close trend.The endoporus of described half a coupler arranges keyway 5, enables half a coupler to be connected by the rotating shaft of keyway and Jian Yu center and to transmit moment of torsion.

Two half a couplers 1 can be movable half a coupler.Can also be a movable half a coupler and a fixing half a coupler such as Fig. 2.

In the shaft coupling work process of embodiment illustrated in fig. 2, one ladder axle is fixing half a coupler, connects driving shaft (left side in figure)；Another half a coupler is movable half a coupler, connects driven shaft (right side in figure).When driving shaft rotates forward, owing to the Vertical Meshing face of two half a couplers engages each other spacing, driven shaft can be transmitted torque to；When driving shaft reversely rotates, due to two half a couplers Vertical Meshing face away from, two parts tilt end-acted under make movable half a coupler overcome spring force axially to remove, thus moment of torsion cannot be transmitted, serve anti-reverse effect.
