High and low temperature tension machine screw clearance how to lift?

High and low temperature tension machine screw clearance how to lift? When users use the testing machine, there will be some problems, including how to clear the gap between the screw, so in order to remove the gap between the screw, we can understand from several aspects:

High-low temperature tension machine screw and nut cooperation, there is an axial fit clearance, if forced upward or downward reciprocating push nut, there will be turbulence, this turbulent momentum is the amount of clearance. This fit clearance can be eliminated using a clearance cancellation mechanism.

What is clearance elimination? The following is the detailed content:

1 ) Actually, the screw and the nut are fixed in contact with one side of the thread.

2 ) The self-weight of the beam and the nut make the upper side of the screw thread contact, and when the sample load exceeds its own weight, it will change to the lower side contact of the screw thread.

3 ) Clearance clearance mechanism consists of transmission nut, guide screw, load-bearing nut, compression spring and screw.

4 ) The principle is to tighten the screw so that the compression spring is pressurized, the pressure acts on the bearing nut, and the transmission nut is lifted up against the transverse weight, etc., so that the transmission nut is kept in contact with the lower side of the screw thread.

5 ) When the beam bears the load of the sample, no axial turbulence will occur.

High and low temperature tension machine screw clearance how to lift? Through the above analysis and introduction, I believe we have a certain understanding of the release of the screw clearance, if you have other doubts and problems, you are welcome to inquire at any time.
