产品简介

Vertical universal friction and wear testing machine is mainly in the form of sliding, rolling and composite friction, under low contact pressure, choose a different form of friction pair, used for evaluation of lube oil, grease, nylon material such as long as wear resistance, as well as the friction and wear properties of metal materials.

The machine is equipped with three kinds of friction pairs, including four balls, pins and thrust rings, which can provide the ball disk, ball - three pieces, pin - three column, analog CAM, gear and so on.

The machine can measure the friction torque, calculate the friction coefficient, connect the computer, and record the friction coefficient - time curve.

The machine is equipped with a high precision measuring device, which can be used to measure the spot size of the friction pair, or to display, measure and record the computer screen of the friction pair.


执行标准

功能特点

1 spindle and drive system.

The main shaft is driven by the panasonic ac servo motor MHMA102A1 and ac servo speed control system MHDA103A1A. The rated torque of the system motor is 5N. M, stepless speed regulation, and the accuracy is 1% at high speed.

The ac servo motor power is 1 kw, the upper shaft and ac servo motor respectively equipped with a special hunting and active arc tooth belt wheel, ac servo motor through arc-gear synchronous belt MHMA102A1 power is passed on to the main shaft.

This kind of arc tooth synchronous belt has the characteristics of accurate transmission ratio, no skidding, no lubrication, no pollution, small transmission noise, high efficiency, large transmission load and long service life.

The upper part of the main shaft is equipped with a radial ball bearing, which is equipped with a pair of back-to-back thrust bearings at the bottom to withstand the axial test force of up to 1000N.

The system has a high transmission torque at low speed, and it completely changes the disadvantage of the controllable silicon stepless speed regulating system at low speed.

The lower end of the main shaft has M30 x 1.5 external threads, which can extend the function of the testing machine according to the user demand.

2 the oil box

Spindle is hollow shaft, and its lower 1:7 cone hole, can install all kinds of friction pair of chuck, such as pin disk chuck and pin - disk friction pair, inside the hollow spindle rod, when pin - such as disk friction pair in the spindle taper hole, tighten the tie rod can ensure spindle and clamp on the friction pair in the spindle taper hole does not produce any relative sliding.

The normal temperature oil box has two stainless steel semicircle cover, which is stationary during the test and has no contact with the rotating spindle.

Under 3, the main shaft and the lower friction pair plate and the friction torque sensor system.

Guide spindle, deputy plate, under linear ball bearings, both radial ball bearing, the test force sensor, friction torque sensor, thrust ball bearing, roll back nut, screw, when replacing chuck and handling all kinds of friction pair must operation back nut and knurled screw, linear ball bearings can make guide spindle moves up and down under friction small, lightweight flexible, when loaded with high sensitivity, can improve the measurement precision of the friction torque of the bearing.

4 spring microcomputer control loading system.

Applying pressure testing machine test force through the spring type organization with microcomputer control of ac motor system automatically, ac flow motor SZ series dc servo motor, dc motor power passed to a pair of reduction ratio of 80:1 vice worm and worm wheel movement.

Worm gear drive screw rotation, supported by a pair of centripetal thrust roller bearing caused by applying pressure nut plate move up and down (a guide by two solid pillar) applying pressure compression spring, by applying pressure on the board, the load sensor test force exerted on the friction pair, and tested according to the requirement.

The control button is controlled by a microcomputer controlled automatic loading system.

The limit switch can stop automatically after the test end.

Computer measurement and control system.

The control box of the testing machine is on the right side of the seat.

Open the door on the control box can be seen after every electrical plate has a slide, turn the set screw, electrical plate can be pulled back, maintenance and maintenance, testing machine of computer measurement and control system can realize the test force, friction torque, rotational speed, test parameters such as cycle, time measurement and control operation.
