Abstract
The utility model relates to a spacer of bearing roller for hydraulic motor, which comprises a height and a suitable width of two opposite arch sides. The spacer is individually arranged among the rollers arrayed in each roller race in the bearing, thus the adjacent rollers can be separated at a certain space so that the bumping and the friction heat deformation among the rollers can be prevented in the running of the hydraulic motor at high speed rotation, then the smoothness and stability performance of hydraulic motor is improved of the running of the hydraulic motor at high-speed rotation, and the lifecycle is elongated.
Description
Technical field
The utility model relates to a kind of distance piece, be to be used for the oil hydraulic motor roller bearing to separate in each roller circle two adjacent rollers, avoiding roller to clash into each other and frictional heat distortion, and can promote that oil hydraulic motor runs up smooth and easy and steadily and increase the service life.
Background technique
The structure of oil hydraulic motor 1 and function mode thereof such as Fig. 1, hydraulic oil 11 enters housing 13 by separating valve 12 as shown by arrows, producing pressure from piston 15 tops through piston cap 14 passes piston 15 downwards, and drive the eccentric segment 170 of bent axles 17 by the connecting rods in the piston 15 16, make bent axle 17 produce continuously and have the rotation of torsion, can drive the strength of other objects or device with output.
In the structure of above-mentioned oil hydraulic motor 1, Shang Youyi bearing 18 links between connecting rod 16 and the bent axle 17; And be to adapt to being used as power of oil hydraulic motor 1, this bearing 18 is for bearing the roller-type bearing of bigger load.As Fig. 2, shown in Figure 3, above-mentioned bearing 18 has a plurality of transversely arranged roller circles 180 down in the normality design, constitute along its round direction next-door neighbour arrangement by a plurality of rollers 182 in each roller circle 180, then separate between each roller circle 180 with spacer ring 184.Bearer ring 186 outsides by this bearing 18 contact with connecting rod 16; Bearer ring 186 inboards contact with each roller circle 180; Each roller circle 180 is placed on eccentric segment 170 outer surfaces of bent axle 17 again, and the friction when rotating to reduce bent axle 17 also reaches the effect of laborsaving and high speed rotating.
As above-mentioned bearing 18, though separate with spacer ring 184 between each roller circle 180 and can avoid the frictional impact of adjacent roller circle 180, and also leave gap (but the gap is very little) between each roller 182 in each roller circle ugly 80, and can keep the independent rotation of each roller 182 and bring into play the effect of bearing; But, when oil hydraulic motor when running up, roller 182 in indivedual roller circles 180 can come in contact bump and frictional heat causes roller 182 thermal distortions, this phenomenon is with the oil hydraulic motor growth of running time, to make roller 182 only can push each other and can't roll smoothly, last then form the cylinder effect that contracts that bent axle 17 can't be turned for connecting rod 16.
The model utility content
Have to supervise bump and frictional heat distortion can take place between roller when the bearing that known oil hydraulic motor is used is running up, and the problem that causes oil hydraulic motor to turn round smoothly, therefore, the purpose of this utility model is to provide the distance piece of a kind of oil hydraulic motor with bearing roller.
For achieving the above object, the oil hydraulic motor that the utility model provides partition between the bearing roller comprises:
One height has two relative arc-shaped side edges;
One width;
Partition is a plurality of between above-mentioned, and each is installed respectively between each roller in each roller circle in a bearing, separates to the wantonly two adjacent roller spacings that will arrange along this roller circle thus.
Described distance piece, side edge shape that wherein should height with the radial contour of roller at interval corresponding.
Described distance piece, its height is less than the diameter of this roller.
Described distance piece, its width equals the column length of this roller.
Described distance piece, its width is less than the column length of this roller.
By enforcement of the present utility model, separate with distance piece between each roller in each roller circle in a roller bearing, can solve known oil hydraulic motor fully and also further promote oil hydraulic motor in smooth and easy smoothness that runs up and the working life that prolongs this oil hydraulic motor with the disappearance of bearing.Can avoid bump and the distortion of this bearing when oil hydraulic motor runs up, each roller can be rotated smoothly and bring into play this bearing greatest benefit.
Description of drawings
Structure characteristics of the present utility model and effect thereof are clearer to be presented in order to make, and lifts preferred embodiment and conjunction with figs. and is described in detail as follows:
Fig. 1 is the main sectional structure chart of known oil hydraulic motor.
Fig. 2 is the bent axle of public oil hydraulic motor and the combining structure plan view of bearing.
Fig. 3 is the right side view of Fig. 2.
Fig. 4 is the bent axle of the utility model oil hydraulic motor and the combining structure side view of bearing.
Fig. 5 be the utility model distance piece structure and with roller contacting structure figure.
Embodiment
The preferable enforcement structure of the distance piece of the utility model oil hydraulic motor usefulness bearing roller as shown in Figure 4, wherein this distance piece 3 is installed between each roller 182 in each roller circle 180 in a bearing 18, and with wantonly two adjacent roller 182 spacings of arranging in this roller circle 180 separate; And isolate ginseng Fig. 2 between each roller circle 180 with spacer ring 184.As shown in Figure 5, this distance piece 3 comprises that one has the height 30 of two relative arc-shaped side edges 32, and a suitable width (not shown); Wherein should height 30 side 32 shapes corresponding with the radial contour 1820 of the roller 182 at institute interval, so that the arbitrary section profile 1820 of this roller 182 in rotating is provided, can kisses fully with this side 32 and connect and reach and stablize smooth-going running.Above-mentioned distance piece 3 is equal to or less than the diameter of this roller 182 at the preferable height 30 of the utility model, make the partial contour 1820 of this roller 182 can exceed the height 30 of this distance piece 3, contact with the bearer ring 186 of bearing 18 and eccentric segment 170 surfaces of bent axle 17, and do not influence the effect that bearing 18 alleviates gearing friction.As for, this distance piece 3 is equal to or less than the column length 1822 of this roller 182 as Fig. 2 at the preferable width of the utility model.
The above, it only is the utility model preferred embodiment, only structure characteristics of the present utility model is not limited thereto, any the utility model technical field know the knowledgeable usually, according to the utility model such as above-mentioned disclosed technological means, carry out thinking easily and variation or modification person, be all claim of the present utility model and contain.
