For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of high lubricating effect and is convenient to the bearing lubrication system of the more stove motor of oil change in time.
For achieving the above object, the utility model provides following technical scheme: a kind of bearing lubrication system of stove motor, comprise rear inner cap and rear end cap, described rear inner cap is fixedly connected with by screw with described rear end cap, bearing chamber is formed between described rear inner cap and described rear end cap, the junction of described rear inner cap and described rear end cap is provided with sealing ring, comprises lubricating cavity in described bearing chamber, described rear end cap is provided with oil-in and oil-out; Take level height as benchmark, oil-in is positioned at the top of rotating shaft, and oil-out is positioned at the below of rotating shaft; Oil-in and oil-out are respectively equipped with intake plug and go out plug cock, described intake plug and be fuel-displacedly equipped with observation window beyond the Great Wall.
Preferably, the end face that described rear inner cap is connected with rear end cap is respectively equipped with the first protuberance and the second protuberance, and the first protuberance and the second protuberance are cross-linked, and the second protuberance and bearing face are to establishing.
Preferably, shoe cream room is formed with between described rear inner cap and bearing face.
Preferably, the end face that described rear inner cap and rotating shaft are fitted is provided with the breach of some circular arc.
Preferably, back-up ring is provided with between described rear end cap and bearing face.
Preferably, packing ring is provided with between the head of described screw and the outer face of rear end cap.
The utility model has following advantage: the bearing lubrication system of the utility model stove motor adopts the lubricating cavity directly formed in bearing chamber to lubricate bearing, make stove electricity consumption machine can carry out self-lubricating and save lubricating place, wherein on rear end cap, be symmetrically arranged with oil-in and oil-out about rotating shaft, lubricating oil can be poured into from oil-in, pour out from oil-out, lubricating oil is changed, ensure that the effect that lubricating oil provides for simple replacement of, and the continuous lubrication better effects if to stove motor.In addition, be provided with between the rear end cap of the utility model stove motor and bearing face between the head of back-up ring and screw and the outer face of rear end cap and be provided with packing ring, make its sealing effectiveness fine.Moreover, be formed with shoe cream room between rear inner cap and bearing face, make the oil reserve of lubricating oil sufficient, can be more lasting to the lubricant effect of stove motor.Further, the end face of fitting at rear inner cap and rotating shaft is provided with the breach of some circular arc, makes the friction between rotating shaft and rear inner cap less, and can hold lubricating oil in breach, make rotating shaft and rear inner cap carry out lubrication and reach better rotating effect.
Accompanying drawing explanation
Fig. 1 be the bearing lubrication system of the utility model stove motor partly cut open figure;
Fig. 2 is the A portion enlarged diagram of Fig. 1.
In figure: 1. rear end cap; 11. intake plugs; 111. observation window; 12. go out plug cock; 13. second protuberances; 2. inner cap after; 21. first protuberances; 22. breach; 3. bearing; 4. screw; 41. packing rings; 42. sealing rings; 5. shoe cream room; 6. bearing chamber; 7. back-up ring; 8. rotating shaft.
Embodiment
With reference to shown in accompanying drawing, the utility model is further illustrated.
Embodiment: a kind of bearing lubrication system of stove motor, comprise rear inner cap 2 and rear end cap 1, rear inner cap 2 is fixedly connected with by screw 4 with rear end cap 1, bearing chamber 6 is formed between rear inner cap 2 and rear end cap 1, comprise lubricating cavity in bearing chamber 6, rear end cap 1 is symmetrically arranged with oil-in and oil-out about rotating shaft 8, oil-in is positioned at the top of rotating shaft, oil-out is positioned at the below of rotating shaft, and oil-in and oil-out are respectively equipped with intake plug 11 and go out plug cock 12.The junction of rear inner cap 2 and rear end cap 1 is provided with sealing ring 42, and sealing circle 42 is rubber blanket.Be provided with back-up ring 7 between rear end cap 1 and bearing 3 end face, be provided with packing ring 41 between the head of screw 4 and the outer face of rear end cap 1, the sealing effectiveness of the bearing lubrication system of this sample embodiment stove motor is better.
In the present embodiment, bearing chamber 6 i.e. lubricating cavity, to be injected lubricating oil in lubricating cavity by oil-in and lubricates bearing 3.The lubricating cavity directly formed in bearing chamber 6 is adopted to lubricate bearing 3, make stove electricity consumption machine can carry out self-lubricating and save lubricating place, wherein on rear end cap 1, be symmetrically arranged with oil-in and oil-out about rotating shaft 8, lubricating oil can be poured into from oil-in, directly flow out from oil-out under gravity, lubricating oil is changed, ensure that the effect that lubricating oil provides for simple replacement of, and do not need by aid, lubricating oil to be taken out, and the continuous lubrication better effects if to stove motor.And intake plug and the fuel-displaced observation window that is equipped with beyond the Great Wall, after lubricating oil uses a period of time, lubricating oil can become muddy, or lubricating oil causes liquid level to decline due to consumption, can be found out by observation window, so that timely more oil change, observation window can be made up of resistant to elevated temperatures glass.Or, rear end cap 1 arranges oolemma, to observe the oil level of internal lubrication oil.In addition, between rear inner cap 2 and bearing 3 end face, be formed with shoe cream room 5, make the oil reserve of lubricating oil sufficient, can be more lasting to the lubricant effect of stove motor.
