Abstract
The utility model discloses a forced lubricating and cooling labyrinth sealing high-speed bearing seat which belongs to the technical field of machinery. The high-speed bearing seat comprises a bearing body, a left end cover and a right end cover; the upper part of the bearing seat body is provided with an oil inlet pipe and an oil inlet hole, and the lower part thereof is provided with a general oil outlet hole and an oil outlet pipe; the left end cover is provided with a high-pressure oil cavity; the right end cover is provided with a primary oil outlet cavity, a primary oil outlet hole, a secondary oil outlet cavity and a secondary oil outlet hole, and simultaneously a connecting oil pipe is also arranged between the secondary oil outlet cavity and the secondary oil outlet hole. An oil way pipeline loop forms a forced lubricating and cooling loop, designs the oil outlet cavity into two stages, i.e. primary oil return and secondary oil return, simultaneously labyrinth spacing sealing is formed, the rotating speed of the bearing can meet extremely high requirements, and the longest service life can be maintained.
Description
Technical field
The utility model relates to a kind of high speed shaft bearing, relates in particular to a kind of labyrinth seal high speed shaft bearing of pressure lubrication cooling, belongs to field of mechanical technique.
Background technique
Lubricated and the cooling problem of high speed shaft bearing is closed and is switched to its working life.Existing high speed shaft bearing generally adopts bearing grease lubricated, and the disc of employing structure is also arranged, and it is lubricated by disc fluid to be thrown to the bearing place.Rectangular seal or skeleton ring structure are adopted in its sealing usually.
In this type of existing high-speed bearing base device, if adopt the grease lubrication mode, the rotating speed of bearing can not be very high in use; If adopt the disc structure, utilize disc fluid to be thrown to the lubricated mode in bearing place by aperture, because disc is assemblied in and exists assembly error on the main shaft, the dynamic balancing of main shaft will be destroyed, make the main shaft of high speed rotating produce vibration, can reduce the life-span of bearing, the vibration and the noise that produce when working simultaneously have a strong impact on environment.In addition, adopt rectangular seal or skeleton ring structure to make seal ring and main shaft be close to usually, can limit running up of main shaft like this.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of high speed shaft bearing, and it adopts initiatively pressure lubrication and cooling, and by the labyrinth gap sealing, can make the bearing rotating speed reach limit speed, and keeps the longest working life.
The technical solution of the utility model is: a kind of labyrinth seal high speed shaft bearing of pressure lubrication cooling, comprise bearing seat, be positioned at the left end cap and the right end cap at two ends, the bearing seat left and right sides, the top of described bearing seat is provided with oil inlet pipe and oil inlet hole, its underpart is provided with total oil outlet and oil outlet tube, described left end cap is provided with high-voltage oil cavity, described right end cap is provided with and once goes out oil pocket and oil outlet and secondary and go out oil pocket and secondary oil outlet, and described secondary goes out also to be provided with between oil pocket and the secondary oil outlet one and connects oil pipe.
High speed shaft bearing of the present utility model on bearing seat and left and right end cap, has designed the oil line pipe loop, by the input high-voltage oil liquid, forces to flow through bearing, thereby carries out sufficient lubrication and cooling.In addition, will go out oil pocket and be designed to an oil return, secondary oil return two-stage, also form the labyrinth gap sealing simultaneously, and can satisfy the bearing rotating speed and reach high requirement, and keep the longest working life, be highly suitable for high-speed electric main shaft or high-speed electric expreess locomotive.
Description of drawings
Fig. 1 is the plan view of the utility model high speed shaft bearing.
Fig. 2 is the sectional view of high speed shaft bearing shown in Figure 1 along the A-A line.
Embodiment
Below in conjunction with drawings and Examples the utility model structure is described in further detail.
As depicted in figs. 1 and 2, high pressure oil enters the high-voltage oil cavity 6 that is positioned on the left end cap 4 by oil inlet pipe 2 and the oil inlet hole 3 that is positioned at bearing support 1 top, and extreme pressure lubricant flows through bearing 7, and it is carried out lubricated fully and cooling.Lubricant oil by bearing 7 enter be arranged in right end cap 5 once go out oil pocket 9, get back in the fuel tank by once going out oil pocket oil outlet 10, total oil outlet 14, oil outlet tube 15 again.Be leaked to secondary and go out 11 li of oil pockets by once going out oil pocket 9 but in this process, have less amount of lubrication oil, go out oil pocket oil outlet 12 and total oil outlet 14 by connecting oil pipe 13, secondary again, oil outlet tube 15 is got back in the fuel tank.
Because the oil line pipe loop of present embodiment design makes the high speed shaft bearing form lubricated, cooling circuit, in main shaft 8 high speed rotating processes, the lubricated continuously and cooling of circulation has guaranteed the safe handling of high-speed main spindle.
