Abstract
The utility model discloses a crankshaft counterweight structure for controlling lubricating oil splash used in refrigeration compressor. The structure comprises an oil suction pipe, a crankshaft, a crankshaft balance weight and a counterweight piece; a crankshaft helical groove, a crankshaft lateral oil orifice and a crankshaft oil outlet hole are formed on the crankshaft; one side of the counterweight piece is provided with a convex or concave cover which is sleeved on the top of the crankshaft and can seal the crankshaft oil outlet hole. the structure of the utility model not only can achieve the function of balancing the compressor operation, but also can control the lubricating oil from splashing, and can prevent that excessive lubricating oil enters into the refrigeration system caused by the splashing.
Description
Technical field
The utility model relates to the counter weight structure of a kind of refrigeration compressor with the control lubricating oil splash, and it is the constituent element of compressor balance system, also has the effect of control lubricating oil splash and fixed point supercharging fuel feeding.
Background technique
In compressor operation,, must there be good lubrication system to guarantee that compressor normally moves because relative movement produces friction between the kinematic pair.For guaranteeing lubricating requirement, the too much phenomenon of lubrication oil circulation amount often appears in refrigeration compressor, and too much lubricant oil enters refrigeration system from the Aspirating valves group, influences the stability of refrigeration system.For solving the too much problem of lubrication oil circulation amount, adopt a kind of supercharging fuel feeding lubricating structure of control lubricating oil splash as shown in Figure 1 at present, comprise fuel sucking pipe 1, bent axle 2, bent axle spiral chute 3, crankshaft counter balance 4, Weight stack 5, rivet 6, bent axle oil outlet 7, plug 8 and side direction oilhole 9, Weight stack 5 is fastening by rivet 6 and crankshaft counter balance, and plug 8 places bent axle oil outlet 7.During compressor operating, fuel sucking pipe 1 is smoked lubricant oil from oil sump, and lubricant oil climbs along bent axle spiral chute 3, when arriving bent axle oil outlet 7, because the effect of plug 8, lubricant oil raises pressure in this gathering, force more lubricating oil to flow to side direction oilhole 9, flow into friction pair then.This lubricating structure can prevent that too much lubricant oil from entering refrigeration system by splashing.Its shortcoming is the technology that has increased the plug 8 and the oil outlet of packing into thereof, has increased cost.Simultaneously, Weight stack 5 places on the crankshaft counter balance 4, is a kind of equilibrium structure of single layout, and tilting moment is bigger, and balance quality is bad.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of lubricant oil that can prevent to cause the excessive refrigeration system that enters because of splashing, and can guarantee the counter weight structure of the refrigeration compressor of the better balance quality of compressor with the control lubricating oil splash again.
For solving the problems of the technologies described above, the utility model refrigeration compressor comprises fuel sucking pipe, bent axle, crankshaft counter balance and Weight stack with the counter weight structure of control lubricating oil splash, described bent axle is provided with bent axle spiral chute, crankshaft side to oilhole and bent axle oil outlet, one side of described Weight stack is the block of evagination indent, and this block is sheathed on the top of described bent axle and described bent axle oil outlet is blocked.
Above-mentioned refrigeration compressor assembles by interference between described block and the described bent axle with the counter weight structure of control lubricating oil splash, described Weight stack.
The above-mentioned refrigeration compressor counter weight structure of control lubricating oil splash, the outside of described Weight stack also superposes and is arranged with Weight stack.
The utility model can reach the equilibrium function of compressor operating owing to adopted above-mentioned technical pattern, can control splashing of lubricant oil again, can prevent lubricating oil splash effectively and causes the excessive refrigeration system that enters.The crankshaft structure of existing relatively compressor control lubricating oil splash, it does not need plug, has reduced part and assembly technology, has reduced cost, can satisfy the balance requirement of compressor operating simultaneously.
Description of drawings
Fig. 1 is the schematic representation of existing refrigeration compressor with the counter weight structure of control lubricating oil splash;
Fig. 2 is the schematic representation of the utility model refrigeration compressor with the counter weight structure of control lubricating oil splash.
Embodiment
As shown in Figure 2, the utility model refrigeration compressor comprises that with the counter weight structure of control lubricating oil splash fuel sucking pipe 1, bent axle 2, bent axle spiral chute 3, crankshaft counter balance 4, Weight stack 5, bent axle oil outlet 7, Weight stack protruding structure 17, Weight stack groove structure 18 and crankshaft side are to oilhole 9, Weight stack 5 places the top of bent axle 2, equilibrium structure with crankshaft counter balance 4 composition symmetric arrangement, reduced tilting moment greatly, balance quality is better.Weight stack 5 is provided with protruding structure 17 and groove structure 18, Weight stack 5 carries out the interference assembling by groove structure 18 and bent axle 2, after assembling is finished, protruding structure 17 and groove structure 18 are blocked bent axle oil outlet 9, stop lubricant oil to splash from here, realize the fixed point supercharging fuel feeding of lubricant oil and the control of oily circulating load, reduce cost, improve compressor efficiency.
Claims (3)
1. refrigeration compressor usefulness is controlled the counter weight structure of lubricating oil splash, comprise fuel sucking pipe, bent axle, crankshaft counter balance and Weight stack, described bent axle is provided with bent axle spiral chute, crankshaft side to oilhole and bent axle oil outlet, it is characterized in that, one side of described Weight stack is the block of evagination indent, and this block is sheathed on the top of described bent axle and described bent axle oil outlet is blocked.
