Description

A kind of multiple oil grooves bearing shell

(1) technical field

The utility model relates to the bearing shell technical field, and what be specifically related to is a kind of multiple oil grooves bearing shell.

(2) background technique

Bearing shell is the sliding bearing important component part, when axle turns round in the bearing shell high speed, it can produce a large amount of heats, the high temperature that direct friction produces burns out bearing shell, also may be because excessive, the excess Temperature of load, lubricant oil exist the factors such as impurity or viscosity be unusual to cause tile kilning, and sliding bearing has just damaged behind the tile kilning, existing bearing shell inwall all is smooth usually, some are also arranged is to be provided with oil groove at inwall, is used for improving lubricating ability.Its deficiency is because the gap between axle and the bearing shell is very little, and lubricant oil is stickiness higher, mobile relatively poor liquid although also used the fuel feeding design of some pressurizations, can not ensure well that still the bearing shell inwall forms uniform oil film.

(3) model utility content

The purpose of this utility model is exactly the deficiency for prior art, and a kind of multiple oil grooves bearing shell is provided, its fuel feeding smoothly, lubricated good, just can discharge chip and grease in the bearing shell by unloading back-up ring.

Technology solution of the present utility model is as follows:

A kind of multiple oil grooves bearing shell, comprise half-terete watt of body, two watts of bodies form a columned bearing shell, the inwall middle part of described watt of body forms a radially main loop oil groove, watt body wall that the main loop oil groove is corresponding is provided with oil hole, also form many axial pass troughs and many radial ringed oil grooves on the inwall of watt body, the main loop oil groove all is connected with all axial pass troughs, and all axial pass troughs and all radial ringed oil grooves all are connected; The two ends of watt body are fixed with back-up ring, and the inner ring diameter of back-up ring is identical with the diameter of the inwall of bearing shell, and back-up ring blocks the two-port of axial pass trough.

Described all axial pass troughs parallel with the bearing shell longitudinal center line, and all radial ringed oil grooves parallel with the main loop oil groove; Every adjacent two axial pass troughs distance is identical, and every adjacent two radial ringed oil groove distances are identical, and all axial pass troughs and all radial ringed oil grooves are evenly distributed on watt body inwall.

Form screw on two end faces of described watt of body, back-up ring is bolted on two end faces that are fixed on watt body.

The width of described main loop oil groove and the degree of depth are the width of axial pass trough and the twice of the degree of depth; Identical 0.1～the 2mm that is of the width of axial pass trough and radial ringed oil groove, the degree of depth of axial pass trough and radial ringed oil groove is the identical 0.5～2mm that is also.

The beneficial effects of the utility model are:

1, its fluid flows to axial pass trough and radial ringed oil groove by the main loop oil groove, the width of main loop oil groove and the degree of depth are the width of axial pass trough and the twice of the degree of depth, the width same depth of axial pass trough and radial ringed oil groove is also identical, form oil pressure at axial pass trough and radial ringed oil groove like this, guarantee the uniform oil film of lubricated formation on the bearing shell body inwall, axle can keep highly lubricating in bearing shell like this, can not produce the phenomenons such as tile kilning, improves the working life of bearing shell.

2, by unloading back-up ring, so that the chip in the bearing shell and grease are in operation, discharge by the two ends of axial pass trough, reduce the damage to bearing shell, improve the working life of bearing shell.

(4) description of drawings

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is plan view of the present utility model;

Fig. 3 is the plan view that removes back-up ring of the present utility model.

Among the figure: 10, bearing shell; 1, watt body; 11, axial pass trough; 12, radial ringed oil groove; 2, main loop oil groove; 3, oil hole; 4, back-up ring.

(5) embodiment

The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

Embodiment: see that Fig. 1 is to shown in Figure 3, a kind of multiple oil grooves bearing shell, comprise half-terete watt of body 1, two watts of bodies 1 form a columned bearing shell 10, the inwall middle part of described watt of body 1 forms a radially main loop oil groove 2, watt body 1 wall of main loop oil groove 2 correspondences is provided with oil hole 3, also form many axial pass troughs 11 and many radial ringed oil grooves 12 on the inwall of watt body 1, main loop oil groove 2 all is connected with all axial pass troughs 11, and all axial pass troughs 11 and all radial ringed oil grooves 12 all are connected; The two ends of watt body 1 are fixed with back-up ring 4, and the inner ring diameter of back-up ring 4 is identical with the diameter of the inwall of bearing shell 10, and back-up ring 4 blocks the two-port of axial pass trough 11.

Described all axial pass troughs 11 parallel with bearing shell 10 longitudinal center lines, and all radial ringed oil grooves 12 parallel with main loop oil groove 2; Every adjacent two axial pass troughs 11 distances are identical, and every adjacent two radial ringed oil groove 12 distances are identical, and all axial pass troughs 11 and all radial ringed oil grooves 12 are evenly distributed on watt body 1 inwall.

Form screw on two end faces of described watt of body 1, back-up ring 4 is bolted on two end faces that are fixed on watt body 1.

The width of described main loop oil groove 3 and the degree of depth are the width of axial pass trough 11 and the twice of the degree of depth; Identical 0.1～the 2mm that is of the width of axial pass trough 11 and radial ringed oil groove 12, the degree of depth of axial pass trough 11 and radial ringed oil groove 12 is the identical 0.5～2mm that is also.

Working principle: in the application of reality, oil enters the main loop oil groove 2 of bearing shell 10 inwalls from oil hole 3, flow into again axial pass trough 11 and radial ringed oil groove 12, because width and the degree of depth of main loop oil groove 3 are the width of axial pass trough 11 and the twice of the degree of depth, identical 0.1～the 2mm that is of the width of axial pass trough 11 and radial ringed oil groove 12, the degree of depth of axial pass trough 11 and radial ringed oil groove 12 is the identical 0.5～2mm that is also, simultaneously, back-up ring 4 has blocked the two ends of all axial pass troughs 11, easy of like this axial pass trough 11 and the stronger oil pressure of radial ringed oil groove 12 foundation, make the oil spill shaft to groove 11 and radial ringed oil groove 12, infiltrate bearing shell 10 inwalls.

And when having grease or chip to produce, by unloading back-up ring 4, make bearing shell 10 at work, grease or chip are discharged to outside the bearing shell 10 by axial pass trough 11, then when axle was out of service, namely bearing shell 10 was loaded onto back-up ring 4 again when quitting work, add again fluid from oil hole 3, reuse.
