Abstract

The invention relates to a clamping device for testing a spindle bearing of a spinning machine, which is used for dynamic performance testing of the spindle bearing. The spindle bearing can be correctly positioned and fixed in dynamic testing so that the clamped spindle bearing can be in a state like operating during the testing, the dynamic performance, vibration and noise of the spindle bearing in the operating state can be tested accurately, the dynamic properties of the spindle bearing can be analyzed effectively prior to spindle installation, the spindle bearing with unacceptable dynamic properties can be separated, the acceptable dynamic properties of a spindle can be ensured, the probability of defective spindle bearings in actual applications can be reduced, and losses caused by unacceptable spindle bearings can also be reduced.

Description

technical field [0001] The invention belongs to the technical field of detection of special parts for textile machines, in particular to a clamping device for testing spindle bearings of textile machines. Background technique [0002] The spindle is one of the main components in the textile industry. Its dynamic performance directly affects the quality of the spun yarn, energy consumption and the physical and mental health of the operator. The spindle bearing is used to support the spindle rod, and its performance has the most direct influence on the dynamic performance of the entire spindle. Spindle bearing is a kind of rolling bearing, but it is very different from ordinary rolling bearing in structure. It has no inner ring, and the outer cylindrical surface on the spindle rod is in direct contact with the rolling body of the spindle bearing. [0003] Generally speaking, the spindle bearings are produced by special manufacturers, and the spindle manufacturers only buy fro...
