Abstract
The invention relates to an insulation structure of a friction disc and an equipment body in a current-carrying friction wear testing machine. The friction disc is fixedly assembled at the external end of a transmission shaft; the transmission shaft is rotatablely assembled on the equipment body; a disconnecting surface is arranged on the transmission shaft of the exposed section at the internal side of the fixed assembly position with the friction disc; the disconnecting surface divides the transmission shaft into a left transmission shaft body section, a right transmission shaft body section and an end section; the left transmission shaft section and the right transmission shaft section have the same axis line and are fixed into a whole; electric insulated coating is coated on the disconnecting surface of at least one side. The insulated coating generally has thin thickness, light weight, large hardness, good rigidity and is not easy to deform when bearing the pressure; as the insulation type between the testing part and the machine body of a current-carrying testing machine, the insulation structure of the invention meets the insulation performance requirement at the high speed, improves the rotation precision and ensures the dynamic balance during the high-speed rotation process simultaneously, avoids the infidelity of the test results and correctly reflects the performance of the test objects.
Description
Technical field
The present invention relates to a kind of current-carrying frictional wear experiment equipment, relate in particular to the insulation system of friction specimen holder and apparatus body in the current-carrying frictional wear experiment equipment.
Background technology
In the current-carrying frictional wear experiment; relate to the alternating current or the direct current of high voltage, big electric current; if test portion and body body do not have the insulation protection measure; electrical equipment on the body is damaged because leak electricity; and test current can be because defective insulation runs off from body; cause the test findings distortion, can not correctly reflect the performance of subjects.And for the insulation of high-speed rotary part and body, rubber and other traditional soft insulation modes are no longer suitable, the stationarity of influence rotation, the particularly dynamic balance under at a high speed.Therefore must seek a kind of good rigidly, intensity height, insulation system that wearing quality is good.
Summary of the invention
At the problems referred to above, task of the present invention provides the insulation system of friction specimen holder and apparatus body in a kind of current-carrying frictional wear experiment, to solve the insulation of high-speed rotary part and body, improves the stationarity of rotation, guarantees the dynamic balance under the high speed.
For finishing above-mentioned task, technical scheme of the present invention is: the insulation system of friction disc and apparatus body in a kind of current-carrying frictional wear experiment, friction disc fixedly is assemblied on the external end head of transmission shaft, transmission shaft rotates and is assemblied on the apparatus body, at friction disc fixedly on the transmission shaft of the inboard revealed section of rigging position, be provided with cleaved facet, two sections transmission shaft body section and termination section about transmission shaft is divided into, about two sections transmission shaft coaxial cables be fixed into one, be coated with electric insulation coating layer at least one side cleaved facet, the anchor clamps platen is an insulation system.
Described cleaved facet is a pair of taper concave surface and taper convex configuration of coincideing mutually.
Described transmission shaft body section cleaved facet is the taper concave surface, described transmission shaft termination section cleaved facet is the taper convex surface, transmission shaft body section off-axis line is provided with tapped blind hole, is provided with through hole on the section axis of transmission shaft termination, and transmission shaft termination section is fastened on the transmission shaft body section by screw.
Described insulating coating is AL
