Description
Technical Field
The utility model relates to a bearing technical field, more specifically say and relate to a high rotational speed oil cooling bearing.
Background
High-speed bearing can generate heat, needs rapid cooling, and such bearing is provided with the oil blanket, and the cooling oil gets into inside the bearing and has cooled off from the outer lane of bearing. The disadvantages are as follows: 1. it adds man-hour and need adorn the oil blanket for the bearing, still need punch installation oil inlet nozzle and play oil nozzle on the bearing inner race simultaneously, and the outer lane of bearing is a tourus, and it is not very convenient to punch on the outer lane of bearing, and the outer lane wall thickness of some bearings is thinner also not be fit for punching, punches simultaneously on the outer lane of bearing and also influences the intensity of bearing inner race easily. 2. The outer ring of the bearing is not very convenient to fix.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an oil cooling bearing to prior art not enough, and need not adorn the oil blanket on its bearing, also need not punch on the bearing inner race, its simple to operate, the outer lane of bearing is also fixed easily.
The technical solution of the utility model is as follows:
an oil-cooled bearing comprises a double-row bearing consisting of an outer ring, an inner ring, a retainer and balls, wherein a shaft is fixed in a central hole of the inner ring, the upper surface of the inner ring is higher than the upper surface of the outer ring, and the lower surface of the inner ring is lower than the lower surface of the outer ring;
the upper cover is screwed on the outer diameter surface at the upper end of the outer ring, the oil inlet nozzle is fixed on the upper cover in a screwed mode, and at least two piston rings are clamped between the inner diameter surface of the upper cover and the outer diameter surface of the inner ring;
the lower cover is screwed on the outer diameter surface of the lower end of the outer ring, the oil outlet nozzle is fixed on the lower cover in a screwed mode, and at least two piston rings are clamped between the inner diameter surface of the lower cover and the outer diameter surface of the inner ring;
an upper cover baffle ring is formed on the upper cover, a lower cover baffle ring is formed on the lower cover, and the upper cover baffle ring and the lower cover baffle ring are fixed on the support through screws.
Two opposite planes are formed in the middle of the outer ring.
The oil inlet nozzle is located on the left side of the inner ring, and the oil outlet nozzle is located on the right side of the inner ring.
The upper cover and the lower cover are the same in structure and size.
The beneficial effects of the utility model reside in that:
the bearing does not need to be provided with an oil seal, and a bearing outer ring does not need to be perforated, so that the bearing is convenient to install, and the outer ring of the bearing is easy to fix.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. an outer ring; 2. an inner ring; 3. a holder; 4. a ball bearing; 5. a shaft; 6. an upper cover; 7. an oil inlet nozzle; 8. a piston ring; 9. a lower cover; 10. an oil outlet nozzle; 11. and (4) a support.
Detailed Description
Example (b): as shown in fig. 1, the oil-cooled bearing comprises a double-row bearing consisting of an outer ring 1, an inner ring 2, a retainer 3 and balls 4, wherein a shaft 5 is fixed in a central hole of the inner ring 2, the upper surface of the inner ring 2 is higher than the upper surface of the outer ring 1, and the lower surface of the inner ring 2 is lower than the lower surface of the outer ring 1;
the upper cover 6 is screwed on the outer diameter surface of the upper end of the outer ring 1, the upper cover 6 is screwed and fixed with an oil inlet nozzle 7, and at least two piston rings 8 are clamped between the inner diameter surface of the upper cover 6 and the outer diameter surface of the inner ring 2;
the lower cover 9 is screwed on the outer diameter surface of the lower end of the outer ring 1, the oil outlet nozzle 10 is screwed and fixed on the lower cover 9, and at least two piston rings 8 are clamped between the inner diameter surface of the lower cover 9 and the outer diameter surface of the inner ring 2;
an upper cover baffle ring 61 is formed on the upper cover 6, a lower cover baffle ring 91 is formed on the lower cover 9, and the upper cover baffle ring 61 and the lower cover baffle ring 91 are both fixed on the support 11 through screws.
The middle part of the outer ring 1 is formed with two opposite planes 1 a.
The oil inlet nozzle 7 is positioned on the left side of the inner ring 2, and the oil outlet nozzle 10 is positioned on the right side of the inner ring 2.
The upper cover 6 and the lower cover 9 have the same structure and size.
The working principle is as follows: the cooling oil enters the space between the outer ring 1 and the inner ring 2 from the oil inlet nozzle 7 and then flows out from the oil outlet nozzle 10, thus cooling the inner ring 2 and the outer ring.
The piston ring 8 is a commercially available piston ring with an inclined opening, which mainly seals the space between the inner ring 2 and the outer ring 1. Two opposite planes 1a are formed in the middle of the outer ring 1, the two opposite planes 1a are convenient for clamping the outer ring 1 by a clamp, and the upper cover 6 and the lower cover 9 are screwed on the outer ring 1.
