Description

Technical Field

[0001] This utility model relates to the field of air conditioning compressor technology, and in particular to a heavy-duty shaft balance block for air conditioning compressors. Background Technology

[0002] In rotary compressors, to eliminate the centrifugal force and torque generated by the eccentric masses of crankshafts and rollers in the compressor shaft system, a mass block, called a balance block, is specially installed on the shaft system, typically on the motor rotor. The balance block can be manufactured separately and then fixed to the rotor; alternatively, it can be integrally formed with the aluminum end ring of the rotor during die-casting. The mass of the balance block is crucial to the overall performance of the compressor. Currently, during the operation of rotary compressors, improper balance block balancing (too large or too small mass) often causes excessive vibration and noise in the compressor shaft system, or excessive crankshaft deflection leading to rotor rubbing. Therefore, we have redesigned a heavy-duty shaft balance block for air conditioning compressors. Utility Model Content
