Abstract

The utility model relates to a self-circulation lubricating device for a bearing, which comprises an oil tank, a connecting oil pipe, a casing and an oil thrower. The inner wall of the casing is fixedly connected to outer rings of rolling bearings. The oil thrower which can relatively rotate with the casing is axially fixed by inner rings of the two rolling bearings. The casing is symmetrically provided with inside and outside communicating oil return holes, the oil return holes are communicated to one end of an oil return pipe, and the other end of the oil return pipe is communicated to the oil tank. Because the outer rings of the rolling bearings and a part of rollers are always dipped in engine oil, when the rolling bearings rotate, the rollers pass through the engine oil so as to obtain good lubricating effect. Furthermore, the oil tank, the oil return pipe and the oil connecting pipe all have the function of heat dispersion, thus, the circulating use of lubricating oil on one hand guarantees the sufficient lubrication to the rolling bearings, and on the other hand causes the lubricating oil to make efficient self-cooling.

Description

Bearing self-loopa lubricating fitting

Technical field:

The utility model relates to the self-lubricating device of bearing self-lubricating device, particularly rolling bearing.

Background technique:

At present, Lubrication of Rolling Contact Bearing adopts lubricating grease or oil lubricating mostly, and the effect of oil lubricating is better, and the long service life of bearing is pressed cooling but need to adopt oil pump to force, and fault is more, leaks easily.

Summary of the invention:

The purpose of this utility model is to provide a kind of sliding certainly device of rolling bearing of high lubricating effect.

Solution of the present utility model is: contain fuel tank, connect oil pipe, housing and disc, inner walls is fixedlyed connected with the outer ring of rolling bearing, can with housing in relative rotation disc axially fix by the inner ring of two rolling bearings, the spill port that is interlinked to the outside in being symmetrical arranged is arranged on the housing, spill port and return tube one end interlink, and the return tube the other end and fuel tank interlink.

Contain 2 fuel tanks, the bottom of 2 fuel tanks interlinks with being connected oil pipe respectively, and 2 return tubes interlink with 2 fuel tanks respectively.

Disc is provided with teeth groove.

After adopting the utility model, because the outer ring and the part roller of rolling bearing are immersed in the machine oil always, when rolling bearing rotates, roller passes through from machine oil successively, thereby high lubricating effect, the teeth groove that disc is provided with is in order to increase the surface of contact of lubricant oil and disc, further improve the splash lubrication effect of disc, in addition, fuel tank, return tube and be connected the effect that oil pipe can both play heat radiation, so recycling of lubricant oil guaranteed the sufficient lubrication to rolling bearing on the one hand, can effectively cool off lubricant oil self again on the other hand.

Description of drawings:

Fig. 1 is the utility model embodiment's a structural representation;

Fig. 2 is the utility model embodiment's a working principle schematic representation.

Among the figure: the 1--disc; The 2--spill port; The 3--spill port; The 4--housing; The 5--fuel tank; The 6--return tube; The 7--return tube; The 8--fuel tank; 9--connects oil pipe; The 10--teeth groove; The 11--rolling bearing; The 12--rolling bearing.

Embodiment:

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:

Consult Fig. 1: contain housing 4, disc 1, housing 4 inwalls are fixedlyed connected with the outer ring of rolling bearing 11,12, can with housing 4 in relative rotation disc 1 axially fix by the inner ring of rolling bearing 11,12, the

spill port

2,3 that is interlinked to the outside in being symmetrical arranged is arranged on the housing 4.

Consult Fig. 2: contain fuel tank 5,8, connect oil pipe 9, spill port shown in Fig. 12 interlinks with return tube 6 one ends shown in Fig. 2, return tube 6 the other ends and fuel tank 5 interlink, spill port shown in Fig. 13 interlinks with return tube 7 one ends shown in Fig. 2, return tube 7 the other ends and fuel tank 8 interlink, the bottom of fuel tank 5,8 respectively be connected oil pipe 9 and interlink.

During use, the inner ring of rolling bearing 11,12 is fixed on the main shaft, disc 1 is by the inner ring axial restraint of rolling bearing 11,12, housing 4 is fixed on the frame, when disc 1 during with main axis rotation, disc 1 gets rid of the effect that oil plays the splash lubrication rolling bearing, simultaneously the lubricant oil of housing 4 inner chambers is clamp-oned the spill port 2 of housing 4, enter fuel tank 5 through return tube 6, lubricant oil enters fuel tank 8 through the connection oil pipe 9 of fuel tank 5 bottoms, enter housing 4 inner chambers by return tube 7 again, form the cooling of circulation fuel feeding.When disc 1 rotates in the opposite direction with main shaft, disc 1 is clamp-oned the lubricant oil of housing 4 inner chambers the spill port 3 of housing 4, spill port 3 through housing 4 enters return tube 7, enter fuel tank 8 again, lubricant oil enters fuel tank 5 through the connection oil pipe 9 of fuel tank 8 bottoms, enter housing 4 inner chambers by return tube 6 again, form the cooling of circulation fuel feeding.

Claims

1, bearing self-loopa lubricating fitting, contain housing, inner walls is fixedlyed connected with the outer ring of rolling bearing, it is characterized in that also containing fuel tank, connect oil pipe, disc, can with housing in relative rotation disc axially fix by the inner ring of two rolling bearings, the spill port that is interlinked to the outside in being symmetrical arranged is arranged on the housing, and spill port and return tube one end interlink, and the return tube the other end and fuel tank interlink.

2, bearing self-loopa lubricating fitting according to claim 1 is characterized in that containing 2 fuel tanks, and the bottom of 2 fuel tanks interlinks with being connected oil pipe respectively, and 2 return tubes interlink with 2 fuel tanks respectively.
