Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, technical solution of the present invention will be carried out below
Detailed description.Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Base
Embodiment in the present invention, those of ordinary skill in the art are obtained all without making creative work
Other embodiment belongs to the range that the present invention is protected.
Referring to fig. 4~Fig. 7, the present invention provides a kind of components that oils for compressor, including oil cover 1,2 and of upper oil pipe
Connection structure, in which: upper oil pipe 2 is connect by connection structure with oil cover 1, when compressor is rotated around its 5 axis of crankshaft, upper oil pipe
2 can be rotated by connection structure oil cover 1 relatively to keep (the interior tool of the shell 6 of compressor of oil sump 4 for protruding into compressor vertically
Have oil sump 4) in.One end of upper oil pipe 2 in the component that oils of existing compressor welds together with oil cover 1, and the other end is stretched
Enter to compress the oil sump 4 of motor spindle, the position of oil cover 1 and upper oil pipe 2 is relatively fixed, and upper oil pipe 2 is stiff, when compressor occurs
When rotating inclination around the axis of crankshaft 5, the upper oil pipe 2 of the component in the prior art that oils can rotate together inclination with oil cover 1,
Oil pipe 2 upper in this way can deviate the vertical guide (plane with horizontal plane, that is, the axis of upper oil pipe 2 can be horizontal by big
In 0 ° of angle), and at this time the refrigeration oil of compressor due to gravity can again to vertical direction assemble, in this way go up oil pipe 2 protrude into
4 depth of oil sump can reduce, in some instances it may even be possible to be detached from oil sump 4.And upper oil pipe 2 provided by the invention is connected by connection structure and oil cover 1
It connects, when compressor is rotated around its 5 axis of crankshaft, upper oil pipe 2 can be rotated by connection structure oil cover 1 relatively, work as pressure in this way
When contracting machine occurs to rotate inclination around the axis of crankshaft 5, the upper oil pipe 2 of the component provided by the invention that oils can be begun by its gravity
It keeps vertically downward eventually, oil pipe 2 protrudes into oil sump 4 to greatest extent in guarantee, and the refrigeration oil in oil sump 4 is drunk up for compressor
Each components lubrication, improves the reliability that oils of compressor.
Wherein, upper oil pipe 2 is L-shaped, including horizontal segment oil pipe 21 and vertical section oil pipe 22, horizontal segment oil pipe 21 and vertical
Section oil pipe 22 is connected, and the free end of horizontal segment oil pipe 21 is arranged in rolling bearing 3 and is connected with the inner ring of rolling bearing 3
It connects, the oil sump 4 of compressor is protruded into the free end of vertical section oil pipe 22.
Specifically, connection structure is bearing arrangement, wherein bearing arrangement can select rolling bearing 3, open up on oil cover 1
There is the mounting hole with rolling bearing 3, the outer ring of rolling bearing 3 is connected with oil cover 1, the inner ring of rolling bearing 3 and upper 2 phase of oil pipe
The outer ring of connection, usual rolling bearing 3 is connect by the way of interference fit with oil cover 1, the inner ring of rolling bearing 3 and upper oil pipe
2 are also connected by the way of interference fit, and the inner ring of rolling bearing 3 can occur to turn by its rolling element (ball) with respect to outer ring
Dynamic, so that inner ring drive oils, the oil cover 1 relatively of pipe 2 rotates.In addition, rolling bearing 3 can both bear axial load
Radial load can be born again, and connection structure is used as using rolling bearing 3, so that overall structure is also relatively easy.
Since the sealing between oil cover 1 and rolling bearing 3 may be implemented in the outer ring interference fit of oil cover 1 and rolling bearing 3,
It may be implemented by way of interference fit between rolling bearing 3 and upper oil pipe 2 between the inner ring of rolling bearing 3 and upper oil pipe 2
Sealing, therefore have gap between the rolling element (ball) of only rolling bearing 3, oil can be flowed out by the gap.As this
Inventive embodiments optionally embodiment, rolling bearing 3 is at least towards sealing ring is provided on the end face inside oil cover 1, in this way
Better seal may be implemented between oil cover 1, rolling bearing 3 and upper oil pipe 2, oil is prevented to pass through the rolling element of rolling bearing 3
Between gap outflow.
The present invention also provides a kind of compressors, including the component that oils, and the component that oils is above-mentioned for compressor
Oily component, compressor are horizontal compressor.The reliability that oils for being used for the component that oils of compressor is preferable, can make compressor
Oil reliability raising, the component that oils the frozen oil in compressor oil sump 4 can be drunk up for compressor each components lubrication,
So that the performance and reliability of compressor are higher.
In addition, the present invention also provides a kind of air conditioner, including above-mentioned compressor.When compressor provided by the invention is answered
When on motorcar air conditioner, the axis of its crankshaft 5 is vertical with vehicle traveling direction when compressor is installed, and automobile is in climb and fall
Compressor occurs around the rotation of 5 axis of crankshaft so that run-off the straight, and oil sump 4 is under the effect of gravity again to vertical inside compressor
The aggregation of face direction, upper oil pipe 2 can also be remained under the effect of gravity straight down, to greatest extent by rolling bearing 3 at this time
Protrude into oil sump 4, the reliability that oils of compressor is improved, to improve the performance of motorcar air conditioner.
More than, only a specific embodiment of the invention, but scope of protection of the present invention is not limited thereto, and it is any to be familiar with
Those skilled in the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all cover
Within protection scope of the present invention.Therefore, protection scope of the present invention should be subject to the protection scope in claims.
