The utility model also discloses a reciprocating compressor of using above-mentioned cylinder block.
Description
[technical field]
The utility model relates to the cylinder block of compressor, relates in particular to a kind of cylinder block with oil storage tank and uses the reciprocal compressor of this cylinder block.
[background technique]
Present reciprocal compressor has oil feeding mechanism, oil feeding mechanism is by offer axial oilhole at bent axle, during work under centrifugal action, lubricant oil is inhaled into the axial of bent axle, and rise to the axle journal place of bent axle, and the lubricant oil that spills through crank rotation forms effect lubricated and that seal to the parts such as cylinder and piston and each surface.This employing splash lubrication mode causes when compressor start stage or slow-speed of revolution startup easily to the structure of cylinder and piston fuel feeding, and cylinder and piston is difficult to obtain sufficient lubrication, and frictional force is larger, and power consumption is higher.
[model utility content]
It is a kind of simple in structure, easy to process that the utility model provides, and reliable operation when compressor start stage or low-speed running, for piston and cylinder provide lubricated, reduces to start and the frictional force when turning round, and reduces the cylinder block with oil storage tank of power consumption.
In order to realize above-mentioned model utility purpose, the technical solution adopted in the utility model is:
A kind of cylinder block with oil storage tank comprises that bent axle supports the gentle cylinder body of pedestal, and bent axle supports the side that pedestal is arranged at cylinder block, and the bent axle pilot hole center line that bent axle supports pedestal is vertical with cylinder block upper piston chamber center line; The cylinder block outside corresponding to described piston cavity is provided with to the oil storage tank of piston cavity supplying lubricating oil, and the radial wall of cylinder block is provided with the oil guiding hole that is communicated with piston cavity and oil storage tank, is provided with the aperture of oil guiding hole at the non-compression work cavity wall place of piston cavity.
Preferably, described oil storage tank is arranged at outer rim place, cylinder block top.
Preferably, the sectional area of described oil guiding hole is less than 16mm
2
Preferably, it is one-body molded that described bent axle supports pedestal and cylinder block employing cast aluminium or cast iron materials.
A kind of reciprocal compressor, this compressor uses above-mentioned cylinder block, and this compressor is applicable to refrigeration refrigerator.
The beneficial effects of the utility model are:
The utility model is by being provided with to the oil storage tank of piston cavity supplying lubricating oil at outer rim place, cylinder block top, non-compression work cavity wall place in piston cavity is provided with the oil guiding hole that is communicated with oil storage tank, be splashed to the lubricant oil in the oil storage tank when starting first by compressor, to follow-up piston lubrication in the work of cylinder piston chamber, especially when compressor start stage or low-speed running, can effectively reduce the frictional force of piston and cylinder, reduce frictional loss, reduce power consumption; The better effects if that when the frequency-changeable compressor low cruise, plays.
[description of drawings]
Fig. 1 is that master of the present utility model looks the cross section structure schematic representation;
Fig. 2 is plan structure schematic representation of the present utility model.
[embodiment]
A kind of cylinder block with oil storage tank, as depicted in figs. 1 and 2, comprise that bent axle supports pedestal 1 and cylinder block 2, bent axle supports the side that pedestal 1 is arranged at cylinder block 2, and bent axle pilot hole 10 center lines that bent axle supports pedestal 1 are vertical with cylinder block 2 upper piston chambeies 20 center lines; Outer rim place, cylinder block 2 top in piston cavity 20 correspondences is provided with to the oil storage tank 3 of piston cavity 20 supplying lubricating oils, and the radial wall of cylinder block 2 is provided with the oil guiding hole 4 that is communicated with piston cavity 20 and oil storage tank 3; Be provided with the aperture 40 of oil guiding hole 4 at the L inwall place, non-compression work chamber of piston cavity 20, like this, the exit position of oil guiding hole 4 (aperture 40) is in closed state always in the piston movement process, do not affect the reciprocating type compression work of piston.
Wherein, the sectional area of oil guiding hole 4 is less than 16mm
2, oil guiding hole 4 such diameter are convenient to the fuel feeding to non-compression work cavity wall place; It is one-body molded with cylinder block 2 employing cast aluminiums or cast iron materials that bent axle supports pedestal 1, is convenient to the cylinder block manufacturing.
The utility model is applicable to the reciprocal compressor in the refrigeration refrigerator, by at outer rim place, cylinder block 2 top oil storage tank 3 being set, non-compression work cavity wall place in piston cavity 20 is provided with the oil guiding hole 4 that is communicated with oil storage tank 3, be splashed to the lubricant oil in the oil storage tank 3 when starting first by compressor, in the reciprocating type compression work while of piston, lubricated to piston and cylinder inner wall, especially when compressor start stage or low-speed running, when the bent axle upper oil hole splashes for shortage of oil, can utilize the lubricant oil in the oil storage tank 3, effectively reduce the frictional force of piston and cylinder, reduce power consumption.
The above embodiment for preferred embodiment of the present utility model, is not to limit practical range of the present utility model with this just, and the equivalence that all shapes according to the utility model, structure and principle are done changes, and all should be covered by in the protection domain of the present utility model.
