Abstract
The utility model relates to a rolling rotor air conditioning compressor with a chamfer oil tank, which comprises an upper cylinder cover, an oil tank is arranged in an inner hole of the cylinder cover, the two sides of the oil tank are equipped with a chamfer, and the oil tank keeps away from a compressed face where the upper cylinder cover and a crankshaft pressure are maximally and closely combined. The utility model is capable of effectively increasing the fuel delivery of the upper cylinder cover and reducing the wear of the upper cylinder cover and a crankshaft. The input power is prevent from being increased because an upper bearing is wore, the COP value of the compressor is prevent form being affected, the operation reliability of the compressor is increased, the crankshaft is prevent from deforming or leaning to possibly lead to produce electromagnetic sound after the crankshaft is wore.
Description
Technical field
The utility model relates to a kind of rolling rotor-type air condition compressor with chamfering oil groove, the air condition compressor that especially has chamfering relevant for a kind of oil groove of upper cylinder cover.
Background technique
Referring to figs. 1 to shown in Figure 6, rolling rotor-type air condition compressor upper cylinder cover 9 constitutes the active chamber of rolling rotor type compressor with piston, blade, following cylinder cap (two (n) cylinder compressor comprises intermediate plate) (not shown) cylinder etc.; Upper and lower cylinder cap endoporus and end face constitute the spring bearing of crankshaft rotating together; Offer relief opening (also have at following cylinder cap and offer relief opening) at upper cylinder cover 9, realize the compressor air-discharging function; The rolling rotor type compressor pump housing and rotor portion fix by upper cylinder cover 9 (or cylinder) and housing welding.
Compressor upper cylinder cover 9 internal diameters and bent axle external diameter constitute sliding bearing; its endoporus and bent axle generation sliding friction; for the abrasion that reduce between these two product improve bearing life; upper cylinder cover 9 internal diameters and bent axle external diameter need oil lubrication; specific practice is offered oil groove 91 in upper cylinder cover 9 inner diameter wall; Oil Guide path of processing on upper cylinder cover 9 inner diameter wall; make lubricant oil to be lubricated cylinder cap internal diameter and bent axle surface along this path; and formation one deck oil film; avoid upper cylinder cover 9 directly to contact the generation dry friction with bent axle; thereby protection upper cylinder cover 9 and bent axle, and reduce frictional loss, improve compressor efficiency.
In the prior art, rolling rotor type compressor upper cylinder cover 9 oil grooves 91 are single spiral half slot, extend to the cylinder cap upper-end surface from the cylinder cap base plane.But restriction makes that the oil groove degree of depth and groove width all can not be excessive with other structure (annular groove) owing to be subjected to upper cylinder cover 9, otherwise will influence cylinder cap intensity.
In these prior aries, upper cylinder cover 9 oil grooves 91 are the half slot of single-screw shape, and upper cylinder cover 9 can take place in the test of compressor related reliability has inordinate wear with the bent axle surface of contact.Find that by test and calculating the main cause of these wearing and tearing is that upper cylinder cover 9 inwall oil films form deficiency and oil groove is jagged and causes.
Summary of the invention
The technical problem that the utility model solved provides a kind of rolling rotor-type air condition compressor with chamfering oil groove, its notch to oil groove has appended circular arc chamfering, can reduce burr and have possibility, reduce the inordinate wear of bent axle and cylinder cap, improve the reliability and the efficient of compressor
The technical problem that the utility model solved provides a kind of rolling rotor-type air condition compressor with chamfering oil groove, it has appended circular arc chamfering to the notch of cylinder cap oil groove up and down, can make the oil groove groove width increase, improve the utilization rate of refrigerator oil in bearing portion.
In order to solve the problems of the technologies described above, the utility model provides a kind of rolling rotor-type air condition compressor with chamfering oil groove, this compressor includes a upper cylinder cover, offer an oil groove in the cylinder cap endoporus, the dual-side of this oil groove all has a chamfering, and oil groove is avoided upper cylinder cover and bent axle pressure maximum combined compression face the most closely.Following cylinder cap also can be offered the structure same with upper cylinder cover.
The beneficial effect that the utility model brought is the fuel delivery that can effectively strengthen upper cylinder cover, reduces the wearing and tearing of upper cylinder cover and bent axle, improves compressor reliability; And prevent to influence the COP value of compressor because the wearing and tearing of upper bearing (metal) increase input power, can also avoid bent axle abrasion back crankshaft deformation or inclination might cause the generation of electromagnetism sound.

Embodiment
To Figure 12, it shows a kind of preferred embodiment with rolling rotor-type air condition compressor of chamfering oil groove of the utility model with reference to figure 7.This compressor includes a upper cylinder cover 1, offers an oil groove 11 in upper cylinder cover 1 endoporus, and the dual-side of this oil groove 11 all has a chamfering 12.The pressure maximum combined that the oil groove of opening 11 need be avoided upper cylinder cover 1 and bent axle (not shown) is compression face 13 the most closely.The formation method of oil groove 11 can be this oil groove 11 is appended to carry out notch and mill chamfering once milling out oil groove 11 back.
Known to those skilled in the art, drawings and Examples of the present utility model are only for illustrating that function of the present utility model, structure and principle should not become the restriction in the utility model understanding; Simultaneously, the purpose of this utility model all realizes.The foregoing description may be had some change under the situation that does not break away from the utility model principle, so protection of the present utility model should be as the criterion with the scope described in claims.
