Abstract
The utility model discloses a commercial air conditioner compressor crankshaft which comprises a long shaft, wherein the long shaft is in a ladder shape, one side of the long shaft is provided with eccentric parts, two eccentric parts are arranged, one side of the eccentric parts is provided with a short shaft, the surfaces of the long shaft, the short shaft and the eccentric parts are all provided with oil holes, one side of the eccentric parts is provided with holes in a penetrating way, and the insides of the long shaft, the short shaft and the eccentric parts are provided with oiling channels. Through setting up oiling passageway, oilhole for because of the oil film thickness that the refrigerating oil volume and produced in this cooperation region of high-speed rotation are enough big enough, and then reduce the bent axle and produce mechanical friction loss because of deflection deformation and upper and lower flange.
Description
Technical Field
The utility model relates to the technical field of compressors, in particular to a commercial air conditioner compressor crankshaft.
Background
The power source inside the compressor is mainly a motor, and the crankshaft rotates at high speed in the pump body under the drive of the motor, so that the property change of the refrigerant is realized, and the purposes of refrigeration and heating are achieved; the oil supply system of the compressor introduces or leads the refrigerating oil (lubricating oil) into or out of the crankshaft under the action of the rotation centrifugal force of the crankshaft, so that a refrigerating oil film is formed on the surfaces of movable parts such as the crankshaft, so as to lubricate the movable parts, ensure that the movable parts such as the crankshaft can flexibly operate, and efficiently transmit torque.
When the crankshaft rotates under the drive of the motor, the crankshaft can generate certain deflection deformation due to the integral structural characteristic, the compressor pump body is composed of high-precision parts, so that mechanical friction is generated on the internal parts of the pump body when the crankshaft is deflected, the operation reliability of the whole pump body is seriously affected by abrasive dust generated by the mechanical friction, in the related art, in order to solve the mechanical friction generated by the deflection deformation of the crankshaft, an oil pump is usually added at the bottom of the crankshaft, and the oil supply quantity is increased to solve the problem, and the mode leads to higher operation cost of the compressor.
Disclosure of Invention
The utility model aims to provide a commercial air conditioner compressor crankshaft, which can ensure that the refrigerating oil in a matching area is enough and the thickness of an oil film generated by rotating the matching area at high speed is enough through an oil injection channel and an oil hole, thereby reducing the mechanical friction loss of the crankshaft caused by deflection deformation and upper and lower flanges.
To achieve the above object, there is provided a commercial air conditioner compressor crankshaft comprising: the oil injection device comprises a long shaft, wherein an eccentric part is arranged on one side of the long shaft, a short shaft is arranged on one side of the eccentric part, oil holes are formed in the surfaces of the long shaft, the short shaft and the eccentric part, an opening is formed in one side of the eccentric part in a penetrating manner, and an oil injection channel is formed in the long shaft, the short shaft and the eccentric part.
According to the commercial air conditioner compressor crankshaft, two eccentric parts are arranged.
According to the commercial air conditioner compressor crankshaft, the long shaft is in a step shape.
The utility model aims to provide a commercial air conditioner compressor crankshaft, which mainly has the innovation points that:
1. according to the commercial air conditioner compressor crankshaft, the oil injection channel and the oil hole are formed, so that the refrigerating oil in the matching area is sufficiently rotated at a high speed, the thickness of the generated oil film is sufficiently large, and further mechanical friction loss of the crankshaft due to deflection deformation and the upper flange and the lower flange is reduced.
2. This commercial air condition compressor bent axle through setting up the trompil, lightens the weight of eccentric part, reduces the required energy when eccentric part rotates, reduces the energy consumption, improves air condition compressor's efficiency, reduces vibrations simultaneously, noise reduction.
3. The crankshaft of the commercial air conditioner compressor is simple in structure, fewer in parts, low in cost of the air conditioner compressor and capable of meeting the requirement of light weight of the crankshaft.
Additional aspects and advantages of the utility model will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the utility model.
