Abstract
The utility model relates to a there is not oily scroll compressor bearing lubrication mechanism, include: casing, first bearing and second bearing, include: outer bearing seat, fixed scrollwork, screw hole, unthreaded hole, crank axle, bearing frame, outer bearing seat, casing and fixed scrollwork constitute an inclosed cavity, first bearing and second bearing be in in this inclosed cavity, the crank axle make the hollow shaft, this hollow shaft comprises the threaded holes and unthreaded hole in proper order, bearing frame and crank axle constitution cavity, screw hole, unthreaded hole and cavity constitute the passageway of the lubricated part that feeds through first bearing and second bearing, still include: one fills lubricating oil mechanism, fill lubricating oil mechanism and screw hole link to each other, because the maintenance operations process does not always have any action of disassembling, has alleviateed maintainer work load, has reduced maintainer's experience in market operation requirement yet, has reduced rotatable parts's quality, the certain degree improves the whole efficiency of compressor.
Description
Technical field
The utility model relates to a kind of oil-free scroll formula bearing of compressor lubricating structure, particularly relates to the oil injection structure of this lubricating structure.
Background technique
Use after length at oil-free scroll formula compressor, among the bearing that lubricant grease must be injected into anti-rotation, carry out the work of cycle maintenance.But the oiling mode of prior art is after the part of the fixed scroll needing to disassemble body, the carrying out of oiling can be carried out for the pump nozzle of bearing.
As shown in Figure 1, be that prior art oil-free scroll formula compressor uses more a kind of bearing lubrication oil injection structure.After needing first to remove the left part (removing in figure) such as half side fixed scroll and wind scooper in the drawings, oiling instrument 39 is used to be injected in the oil sealing cavity 38 that bearing mounting base 33, crankshaft 36 and clutch shaft bearing 37 three formed jointly by lubricant grease through the oilhole 34 that enters of pump nozzle 35 and bearing mounting base, and then make lubricating grease arrive in clutch shaft bearing 37 and the second bearing 16 cavity, to reach the lubrication of bearing, mark 17 in figure and represent housing.
Fixed scroll is the critical component of oil-free scroll, its fitted position is accurate, needs the professional workforce with certain oil-free scroll machine assembling experience just can carry out, owing to completing in the work of machine general maintenance, that must carry out complexity disassembles assembly process, adds maintenance time.
Summary of the invention
The utility model technical issues that need to address there is provided a kind of oil-free scroll formula bearing of compressor lubricating structure, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: housing, clutch shaft bearing and the second bearing; Also comprise: outer bearing carrier, fixed scroll, tapped hole, unthreaded hole, crankshaft, bearing support; Described outer bearing carrier, housing and fixed scroll form an airtight cavity; Described clutch shaft bearing and the second bearing are in this airtight cavity; Described crankshaft makes hollow shaft, and this hollow shaft is made up of successively tapped hole and unthreaded hole; Described bearing support and crankshaft form cavity; Described tapped hole, unthreaded hole and cavity form the passage being communicated to the lubrication portion of clutch shaft bearing and the second bearing; Also comprise: one fills lubricating oil mechanism; The described lubricating oil mechanism that fills is connected with tapped hole.
Compared with prior art, the beneficial effects of the utility model are: because housekeeping operation process is always without any disassembling action, alleviating attendant's workload, also reducing the operating experience requirement of attendant.Reduce the quality of rotatable parts, to a certain degree improve compressor whole efficiency.
Accompanying drawing explanation
Fig. 1 is the oil injection structure of prior art oil-free scroll formula bearing of compressor.
Fig. 2 is a kind of example structure schematic diagram of the utility model.
Fig. 3 is the another kind of example structure schematic diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
From Fig. 2, Fig. 3: the utility model comprises: housing 9, clutch shaft bearing 6 and the second bearing 7; Also comprise: outer bearing carrier 2, fixed scroll 10, tapped hole 4, unthreaded hole 5, crankshaft 12, bearing support 8; Described outer bearing carrier 2, housing 9 and fixed scroll 10 form an airtight cavity; Described clutch shaft bearing 6 and the second bearing 7 are in this airtight cavity; Described crankshaft 12 makes hollow shaft, and this hollow shaft is made up of successively tapped hole 4 and unthreaded hole 5; Described bearing support 8 forms cavity 11 with crankshaft 12; Described tapped hole 4, unthreaded hole 5 and cavity 11 form the passage being communicated to the lubrication portion of clutch shaft bearing 6 and the second bearing 7; Also comprise: one fills lubricating oil mechanism; The described lubricating oil mechanism that fills is connected with tapped hole 4.
As shown in Figure 2: the described lubricating oil mechanism that fills is a set screw 3 and L-type spanner 1; Described set screw 3 is placed in tapped hole 4, and L-type spanner 1 can regulate the position of set screw 3.
As shown in Figure 3: the described lubricating oil mechanism that fills is a pump nozzle 13 and nozzle 14; Described pump nozzle 13 is placed in tapped hole 4.
Working principle of the present utility model is as follows:
By crankshaft 12 anti-stop scrollwork rotation with carry out axially locating to dynamic scrollwork, and crankshaft 12 and dynamic scrollwork bearing support coordinating by clutch shaft bearing 6 and the second bearing 7, clutch shaft bearing 6 and the second bearing 7 are in the airtight cavity that housing 9 and fixed scroll 10 formed.Crankshaft 12 is made hollow shaft, and hollow cavity is made up of tapped hole 4 and unthreaded hole 5.Grease is filled in hollow cavity, and lock set screw 3, thus make when to machine maintenance, set screw 3 can be regulated to move (Fig. 2) along arrow by using L spanner 1, make lubricating grease in tapped hole 4 and unthreaded hole 5 discharged to cavity 11, and then arrive in the cavity of clutch shaft bearing 6 and the second bearing 7, thus realize the object of clutch shaft bearing 6 and the second bearing 7 lubrication.
Set screw 3 in Fig. 2 can also be replaced by the pump nozzle 13 in lower Fig. 3 by the utility model, is refueled by nozzle 14, thus also realizes the object of clutch shaft bearing 6 and the second bearing 7 lubrication.
