Description

The desk-top motor of a kind of cross-shaped convex-concave is to dragging experiment coupling
Technical field
The utility model relates to a kind of coupling, is specifically related to the desk-top motor of a kind of cross-shaped convex-concave to dragging experiment coupling.
Background technique
Coupling is a kind of two axles (driving shaft and driven shaft) different in connection for transmission mechanism that are used for, and makes it rotate and the component of machine of transmitting torque with identical speed.In the particular/special requirement occasion of some, as in the power transmission system of high-speed overload, some coupling also has buffering, vibration damping, and improves the effect of axle system motion transmission stability.Conventional coupling forms primarily of two-part, is connected respectively with main drive shaft with from transmission shaft.In drive system, most of power-driven mechanism is all connected with driven-mechanism by coupling.According to the difference of application, coupling has much different kinds, structure is also varied, coupling is needed to have buffering at some, the occasion of vibration damping and raising system axle system dynamic stability performance, traditional mechanical transmission instrument major part uses plum-blossom sleeve cartridge type or elastic column axis coupling to connect, the coaxality of this Placement diaxon system not easily ensures, and the gap of connected element is larger, axle ties up in rotary course strong impact load and vibration, particularly when multiple coupling carries out series connection use, because axle system lengthens, Product Precision can be made to be difficult to ensure, also reduce the working life of associated structural component simultaneously, also can produce corresponding noise pollution, serious conditions brings potential potential faults may to whole transmission system.Particularly for two machines to the motor experiment dragged, can be higher to the requirement of coupling, the quality of coupling performance directly has influence on the test result of motor performance, motor not easily adjusts due to its axisymmetric degree dragging in experiment conventional elastic coupling, very high to the technical requirements of installation testing personnel, easily cause decentraction.Simultaneously, due at motor to when dragging experiment, needing to test in the experiment of rotating torques, also need to seal in torque sensor in experiment axle system, whole like this axle system at least needs 2 cover elastic coupling to carry out series coupled transmission, thus further add the difficulty of installing coupling, too increase the axial length of experiment simultaneously.
Model utility content
The utility model is solve existing coupling not easily to regulate symmetrical problem at motor to dragging the axle center existed in test, and then provides the desk-top motor of a kind of cross-shaped convex-concave to dragging experiment coupling.
The utility model is solve the problems of the technologies described above the technological scheme taked to be:
The desk-top motor of a kind of cross-shaped convex-concave of the present utility model comprises the first coupling shaft to dragging experiment coupling, first land, cross boss, second coupling shaft, second land and resilient pad, first coupling shaft, first land, second land and the second coupling shaft are coaxially arranged successively, and the first coupling shaft is fixedly connected with the first land, and the second coupling shaft is fixedly connected with the second land, cross boss is arranged on the inner side end of the first land, the side face of cross boss posts resilient pad, the inner side end of the second land is provided with the cross recess matched with cross boss, cross boss is arranged in cross recess.
The utility model has following beneficial effect:
One, the utility model adopts the mutual pin structure of corresponding bump type, when driving shaft drives the first coupling shaft to rotate, because the first coupling shaft, the first land, cross boss are as a whole, the rotation torque that first coupling shaft obtains has been directly passed to cross boss, certain damping, buffering effect can be started at the process Elastic pad of the transmitting torque that is of coupled connections of cross boss and cross recess, thus alleviate the collision between driving mechanism and follower.And directly moment of torsion is passed to cross recess due to cross boss, and the second land and the second coupling shaft as a whole, second coupling shaft directly passes to driven axle moment of torsion, this configuration reduces intermediate connecting ring joint, thus improves the stability of coupling and transmission system.
Two, the utility model easily ensures the coaxality of axle system when mounted, thus it is too much to solve male part in existing motor coupled drive process, the jiggly problem of torque transmission, improve the accuracy of torsion-testing in coupled drive process, improve the practicability of product and the security and stability of system simultaneously.
Decrease the tedious steps of clamping pressing plate repeatedly, time saving and energy saving.
