Description
Technical field
The utility model relates to a kind of selflubricating primary and secondary cylindrical gears.
Background technique
Current gear structure is on the market simple, need in use to inject lubricant oil to the engaging piece of gear, but it is larger for primary and secondary gear oiling difficulty when oiling, and be easy to the uniform not problem of oiling, and common primary and secondary gear cannot select fixed structure or bascule voluntarily, uses very inconvenient.
Model utility content
The technical problems to be solved in the utility model is: for solving above-mentioned Problems existing, provides a kind of selflubricating primary and secondary cylindrical gears, solves the uneven problem with changing the kind of drive of common primary and secondary gear oiling.
The utility model solves the technological scheme that its technical problem adopts: a kind of selflubricating primary and secondary cylindrical gears, comprise gear, gear upper surface offers blind round hole, blind hole bottom center position offers the first axis hole, internal gear is provided with in blind hole, internal gear central position offers the second axis hole, internal gear is flexibly connected with blind hole through the first axis hole and the second axis hole by rotating shaft, gear inside offers transport pipe, blind hole inwall offers the oil inlet pipe be connected with transport pipe, gear outer side wall offers the oil outlet tube be connected with transport pipe, oil inlet pipe, oil outlet tube and gear are centrally located on same straight line, oil inlet pipe and oil outlet tube lay respectively at two ends, gear center, internal gear offers positioning hole, blind hole bottom surface offers the locating slot corresponding with positioning hole, internal gear inserts positioning hole by positioning shaft and is fixedly connected with blind hole with locating slot.
Further, in order to prevent wearing and tearing, internal gear outer diameter is less than blind hole inner diameter.
Further, conveniently install transmission shaft, the first axis hole is identical with the second axis hole size.
Further, in order to protect internal gear, internal gear height is identical with blind hole height.
The beneficial effects of the utility model are, selflubricating primary and secondary cylindrical gears of the present utility model arranges oil hole by two ends, and is provided with positioning device on internal gear, thus greatly promote the inside and outside uniformity of oiling and freely convert the kind of drive.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is lateral plan of the present utility model.
1. gear, 2. blind hole, 3. internal gear, 4. rotating shaft, 5. transport pipe, 6. oil inlet pipe, 7. oil outlet tube, 8. positioning hole in figure.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of selflubricating primary and secondary cylindrical gears as depicted in figs. 1 and 2, comprise gear 1, gear 1 upper surface offers blind round hole 2, blind hole 2 bottom center position offers the first axis hole, internal gear 3 is provided with in blind hole, internal gear 3 central position offers the second axis hole, internal gear 3 is flexibly connected with blind hole 2 through the first axis hole and the second axis hole by rotating shaft 4, gear 1 inside offers transport pipe 5, blind hole 2 inwall offers the oil inlet pipe 6 be connected with transport pipe 5, gear 1 outer side wall offers the oil outlet tube 7 be connected with transport pipe 5, oil inlet pipe 6, oil outlet tube 7 and gear 1 are centrally located on same straight line, oil inlet pipe 6 and oil outlet tube 7 lay respectively at two ends, gear 1 center, lubricant oil is thrown to outside from interior by the eccentricity rotated by gear, thus all there is lubricant oil inside and outside making, make oil filling convenient, pasta is more even, internal gear 3 offers positioning hole 8, blind hole 2 bottom surface offers the locating slot corresponding with positioning hole 8, internal gear 3 inserts positioning hole 8 by positioning shaft and is fixedly connected with blind hole 2 with locating slot.
Further; in order to prevent wearing and tearing, internal gear 3 outer diameter is less than blind hole 2 inner diameter, further; conveniently transmission shaft is installed; first axis hole is identical with the second axis hole size, further, in order to protect internal gear; internal gear 3 height is highly identical with blind hole 2; selflubricating primary and secondary cylindrical gears of the present utility model arranges oil hole by two ends, and is provided with positioning device on internal gear 3, thus greatly promotes the inside and outside uniformity of oiling and freely convert the kind of drive.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
