Low-Temperature Torque Tester
I. Introduction:
This Low-Temperature Torque Tester is used to determine the extent to which a test grease retards the rotation of a speciallymanufactured,spring loaded,automotive-type wheel bearing assembly when subjected to low temperatures.Torque values,calculated from restraining-force determinations,are a measure of the viscous resistance of the grease. And it is suitable for grease giving torques of less than 35 N·m at -40℃.
The working principle is:A freshly stirred and worded sampl of test grease is packed into the bearings of a specially-manufactured,automotive-type spindle-bearings-hub assembly.The assembly is heated and then cold soaked at -40 ℃ ,unless another test temperature is specified by the grease specification.The spindle is rotated at 1 rpm and the torque required to prevent rotation of the hub is measured at 60 s.
II. Main Features
1. Standard inboard and outboard tapered roller bearings, LM67010-LM67048 and LM11949
2. Microcomputer temperature controller, temperature control range from normal temperature to -50ºC
3. PT100 temperature sensor, high acquisition accuracy ±0.5ºC
4. This Low Temperature Torque Test Equipment adopts imported compressor cascade refrigeration, low noise.
5. The drive motor adopts a high-speed ratio of 1740/1, which can maintain a stable speed.
6. The low temperature box is insulated with special materials, and there is no temperature influence from the outside.
7. Digital display torque value.
8. The loaded spring can withstand a pressure of 500N and is equipped with a pressure calibration device.
9. Digital display of working hours and alarm.
10.A set of standard grease loader is supplied with Low Temperature Torque Test Equipment.
