Problems solved by technology
[0002] In the actual production of fixed-speed compressors, the lead wires of the motor are often connected incorrectly, which will cause the compressor to reverse the crankshaft (here, clockwise rotation is defined as forward rotation, and counterclockwise rotation is reverse rotation). If the crankshaft is not oiled, each friction pair will not be lubricated, and the friction pair will be stuck in a short time
[0003] The steering of the inverter compressor is affected by the wiring of the control board. When the wiring of the control board is wrong, the rotation of the compressor crankshaft will also be wrong, and eventually the compressor will be stuck.

The invention discloses a crankshaft, a crankshaft assembly thereof and a piston compressor. The crankshaft comprises: a main shaft, a first oil passage with an open lower end is defined in the main shaft, and a first oil hole, a second The upper oil hole, the first oil groove and the second oil groove, the second oil upper hole is arranged above the first oil upper hole, the first oil upper hole is connected with the first oil passage, the lower ends of the first oil groove and the second oil groove are respectively connected with the The first oil hole is connected and the upper ends of the first oil groove and the second oil groove are respectively connected with the second oil hole. The first oil groove and the second oil groove extend upwards to both sides along the circumferential direction of the main shaft respectively. The first oil groove and The rotation direction of the second oil groove relative to the crankshaft is opposite and arranged symmetrically; the eccentric shaft, the eccentric shaft is arranged on the upper end of the main shaft and is arranged eccentrically relative to the axis of the main shaft. Road, the upper end of the second oil passage conducts. According to the crankshaft of the embodiment of the present invention, it can be oiled no matter it is running forward or in reverse.
Description
technical field [0001] The invention relates to the technical field of refrigeration equipment, and more specifically, to a crankshaft, a crankshaft assembly with the crankshaft assembly, and a piston compressor with the crankshaft. Background technique [0002] In the actual production of fixed-speed compressors, the lead wires of the motor are often connected incorrectly, which will cause the compressor to reverse the crankshaft (here, clockwise rotation is defined as forward rotation, and counterclockwise rotation is reverse rotation). If the crankshaft is not oiled, each friction pair will not be lubricated, and the friction pair will be stuck in a short time. [0003] The steering of the inverter compressor is affected by the wiring of the control board. When the wiring of the control board is wrong, the rotation of the compressor crankshaft will also be wrong, and eventually the compressor will be stuck. A need for improvement therefore exists.
