Triple gear on rice machine
The utility model belongs to the component technology field on rice machine, especially relates to a kind of triple gear on rice machine.
At present, the power transmission on rice machine needs to rely on gear assembly to transmit mostly, but the triple gear on existing rice machine can produce larger noise in power transmission; Be exactly that triple gear needs to carry out lubricating maintenance in use for some time in addition, existing structure needs to carry out dismounting to gear and rotating shaft and is separated when maintaining, this just makes lubricating maintenance comparatively loaded down with trivial details; Therefore be necessary to be improved.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, provides a kind of triple gear on rice machine, it have structure simple, effectively can reduce noise and the comparatively convenient and strength-saving feature of lubricating maintenance.
To achieve these goals, the technological scheme that the utility model adopts is: a kind of triple gear on rice machine, comprise gear and be arranged in the first gear, the second gear and the 3rd gear in gear, between described second gear and the first gear and the 3rd gear, be provided with clearance portion; Described clearance portion offers oil through, and described oil through is communicated with the annular groove be opened on gear inwall; Described first gear, the second gear and the 3rd gear are provided with silencing cotton block.
The oil outlet of described oil through is provided with filter screen.
One side end face of described silencing cotton block respectively with the end face of the first gear, the second gear and the 3rd gear.
After adopting said structure, the utility model is compared to the prior art advantageously: structure of the present utility model is simple, oil through in gear clearance portion is communicated with the annular groove of its inside, directly like this add lubricant oil from oil through and can directly lubricate the connecting part of gear and rotating shaft, prevent its long work and wear and tear, and it does not need when needs lubricate to dismantle parts to compare existing structure, simple and convenient; The noise that silencing cotton block produces when can absorb working gear, effectively reduces noise pollution.
Accompanying drawing explanation
Fig. 1 is plane structure schematic diagram of the present utility model.
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model, further illustrates below in conjunction with drawings and Examples to the utility model.
Embodiment, as shown in Figure 1: a kind of triple gear on rice machine, the first gear 11, second gear 12 comprising gear 10 and be arranged in gear 10 and the 3rd gear 13, first gear 11, second gear 12 and the 3rd gear 13 can engage with power take-off, to transmit different power rotating speeds.Be provided with clearance portion 14 between second gear 12 and the first gear 11 and the 3rd gear 13, clearance portion 14 offers oil through 15, oil through 15 is communicated with the annular groove 16 be opened on gear 10 inwall; Like this, just lubricant oil can be transported in annular groove 16 by the oiler of oil through 15 and oil outlet, then carry out upper oil lubrication by the junction of annular groove 16 pairs of gear 10 and rotating shaft, this structure compares existing structure, and it is more simple and convenient.First gear 11, second gear 12 and the 3rd gear 13 are provided with silencing cotton block 20, a side end face of silencing cotton block 20 respectively with the end face of the first gear 11, second gear 12 and the 3rd gear 13; The noise that silencing cotton block 20 produces when can absorb working gear, effectively reduces noise pollution.The oil outlet of oil through 15 is provided with filter screen 17, filter screen 17 is made up of many crisscross polyester fiber yarn, filter screen 17 can filter out the impurity in lubricant oil, prevent these impurity from damaging parts, and polyester fiber yarn is not vulnerable to the corrosion of lubricant oil, can uses for a long time and unnecessaryly to change.
