Abstract
The utility model discloses a compressor with a novel crankshaft, which comprises the crankshaft. The upper portion of the crankshaft is an eccentric shaft, the lower portion of the crankshaft is a straight shaft, three balancing weights for compensating weight are arranged above the eccentric shaft, the balancing weights are stamped by steel plates, a first balancing weight, a second balancing weight, a third balancing weight are sequentially mounted from top to bottom, the first balancing weight and the second weight are sector-annular, the third balancing weight comprises a bow-shaped portion and a connecting portion which are connected with each other, and a hole which is connected with the eccentric shaft is opened on the connecting portion. According to the compressor with the novel crankshaft, the balancing weights for compensating weight are arranged above the eccentric shaft, and the balancing weights have the advantages of being simple in structure, easy to assemble and applicable to compressors in different models after the balancing weights are combined, and the like. During practical assembly, according to crankshafts and pistons in different specifications, balancing weights with different sheets and diameters or balancing weight assemblies can be selected and installed on the eccentric shaft through screws, so that the balance adjusting requirement for the compressors in different specifications are met.
Description
Technical field
The utility model relates to refrigeration compressor, is specifically related to the bent axle of refrigeration compressor.
Background technique
The bent axle of reciprocating type refrigeration compressor generally comprises three parts: d-axis, eccentric shaft and the middle balance portion that is connected.During compressor operating, the power of motor output passes to connecting rod piston through bent axle and is used for pressurized gas, and the reciprocal inertia that produces during piston crank mechanism operation simultaneously also can pass to bent axle and then propagate on the whole compressor movement.The reciprocal inertia of the rotatory inertia of crankshaft eccentric portion and piston crank mechanism is to cause the compressor movement can't keep balance during compressor operating, press vibrative two big main causes.And an important function of crankshaft counterbalance portion is exactly in order to eliminate this two big unfavorable factor, and in order can better the inertia of crankshaft eccentric portion and piston crank mechanism generation to be eliminated, common way is with the diameter of crankshaft counterbalance portion or enlarged in thickness.But the reason that many times is limited to press overall structure insufficient space can't be accomplished counterweight portion size enough greatly, just needs to add the counterweight structure that adds this moment and realizes this goal.
The model utility content
The purpose of the utility model is to provide a kind of compressor with new type crank, and this compressor arrangement is novel, and using effect is good.
The utility model to achieve these goals, the technical solution of employing is:
Have the compressor of new type crank, comprise bent axle, the top of bent axle is eccentric shaft, and the bottom of bent axle is a d-axis; Said eccentric shaft top is provided with at least one equilibrium block that is used for counterweight.
Further, said equilibrium block has one, and equilibrium block comprises arch portion and the joint that is connected, and has the hole that is connected with eccentric shaft on the joint.
Further; Said equilibrium block has three, is first equilibrium block, second equilibrium block, the 3rd equilibrium block from top to bottom successively, and first equilibrium block and second equilibrium block are the fan annular; The 3rd equilibrium block comprises arch portion and the joint that is connected, and has the hole that is connected with eccentric shaft on the joint.
Further, said first equilibrium block, second equilibrium block and the 3rd equilibrium block are integrally formed by welding or riveted joint.
Further, said equilibrium block is stamped to form by steel plate.
The beneficial effect of the utility model:
This kind compressor is provided for the equilibrium block of counterweight above eccentric shaft, have simple in structurely, is prone to assembling, the advantage such as different model compressor that is applicable to capable of being combined.During actual assembled, can select the balancing weight or the balancing weight assemblying body of different sheet numbers, diameter, be installed in the balance adjustment needs that can satisfy the different size compressor on the eccentric shaft through screw according to used bent axle, piston specification difference.

In conjunction with Fig. 3 to Fig. 6; Have the compressor of new type crank, comprise bent axle, the top of bent axle is eccentric shaft 1; The bottom of bent axle is a d-axis 2; Said eccentric shaft 1 top is provided with three equilibrium blocks that are used for counterweight, and equilibrium block is stamped to form by steel plate, is first equilibrium block 301, second equilibrium block 302, the 3rd equilibrium block 303 from top to bottom successively.First equilibrium block 301 and second equilibrium block 302 are the fan annular, and the 3rd equilibrium block 303 comprises the arch portion 31 and joint 32 that is connected, and has the hole 33 that is connected with eccentric shaft 1 on the joint 32.
In sum, compressor is provided for the equilibrium block of counterweight above eccentric shaft, has simple in structurely, is prone to assembling, the advantage such as different model compressor that is applicable to capable of being combined.During actual assembled, can select the balancing weight or the balancing weight assemblying body of different sheet numbers, diameter, be installed in the balance adjustment needs that can satisfy the different size compressor on the eccentric shaft through screw according to used bent axle, piston specification difference.
Certainly; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that the technician in present technique field is made in the essential scope of the utility model also should belong to the protection domain of the utility model.
