Abstract
The utility model discloses a main transmission shaft device for a brush cutter and a jacket thereof. The main transmission shaft device comprises a main transmission shaft, a plurality of jackets and a main transmission pipe, wherein the jackets are sleeved on the main transmission shaft; the main transmission shaft on which the jackets are sleeved penetrates into the main transmission pipe; and the jackets are in interference fit with the main transmission pipe. Each jacket comprises a cylindrical sleeve; and a plurality of cylindrical teeth are arranged outside the sleeve. The main transmission shaft device can ensure that the brush cutter operates more stably with the effects of lower noise and smaller vibration and has safer products and longer working time to the fist failure. The utility model can greatly improve the work applicability of the brush cutter in a forest, a paddy field, a grass land and an shrub forest, so that products can be used in various areas and fields, the application scope of the products is wider, and the promotion value of the products is greatly increased. The utility model further discloses a jacket of the main transmission shaft for the brush cutter.
Description
Technical field
The utility model relates to a kind of brush saw, is specifically related to a kind of final drive shaft device of brush saw.The utility model also relates to a kind of sheath that is used for the final drive shaft of brush saw.
Background technology
The final drive shaft diameter of brush saw is 8mm, and length is 1530mm, and rotating speed is up to more than the 8500rpm during work.Axiality and vibratory output when guaranteeing this superfine shaft transmission are the keys of making the brush saw complete machine.
At present, the final drive shaft of brush saw generally adopts all-plastic sheath or bearing to support.But all there is defective in these two kinds of methods.Adopt the all-plastic sheath, machine is easy to produce high temperature because of oil starvation, causes main shaft and sheath sintering.Adopt bearing, then the vibratory output of machine is very big, and bearing also damages easily, and the utmost point is not easy to change after the damage of bearings, can only change the main transmission pipe.
The utility model content
Technical problem to be solved in the utility model provides a kind of final drive shaft device of brush saw, axiality when it can guarantee the final drive shaft transmission and vibratory output.
For solving the problems of the technologies described above, the technical solution of the final drive shaft device of the utility model brush saw is:
Comprise final drive shaft, sheath, main transmission pipe, be arranged with a plurality of sheaths on the final drive shaft, the final drive shaft that is arranged with sheath is arranged in the main transmission pipe; Be interference fit between described sheath and the main transmission pipe.
Described sheath comprises cylinder-shaped sleeve, and sleeve pipe is provided with a plurality of columnar tooth outward.
Described a plurality of sheath axially evenly distributes along final drive shaft.
The length of described main transmission pipe is less than final drive shaft.
The maximum outside diameter of described sheath is greater than the internal diameter of main transmission pipe.
The internal diameter of described sheath is greater than the external diameter of final drive shaft.
The utility model also provides a kind of sheath that is used for the final drive shaft of brush saw, and its technical solution is:
Comprise cylinder-shaped sleeve, sleeve pipe is provided with a plurality of columnar tooth outward.
The technique effect that the utility model can reach is:
The utility model can make that the running of brush saw is more steady, noise is littler, vibrates forr a short time, and product is safer, and the first-time fault working time is longer.The utility model can greatly improve the work applicability of brush saw in woodland, rice field, meadow, filling forest zone, makes that product can be in the multi-field practicality of multizone, and application range of products is more extensive, greatly increases product promotion and is worth.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the decomposing schematic representation of the final drive shaft device of the utility model brush saw.
Description of reference numerals among the figure:
1 is the main transmission pipe, and 2 is sheath,
3 is final drive shaft.
Embodiment
As shown in Figure 1, the final drive shaft device of the utility model brush saw comprises final drive shaft 3, sheath 2, main transmission pipe 1, is arranged with a plurality of sheaths 2 on the final drive shaft 3, and a plurality of sheaths 2 axially evenly distribute along final drive shaft 3; The final drive shaft 3 that is arranged with sheath 2 is arranged in the main transmission pipe 1; Main transmission pipe 1 is stretched out at the two ends of final drive shaft 3.
The length of main transmission pipe 1 is less than final drive shaft 3.
Sheath 2 comprises cylinder-shaped sleeve, and sleeve pipe is provided with a plurality of columnar tooth outward.
Be interference fit between sheath 2 and the main transmission pipe 1.
Sheath 2 inner cylindrical sleeve pipes adopt the high die casting of copper based powder metallurgy material to form, and outside columnar tooth is an acrylonitrile-butadiene rubber.
The maximum outside diameter of sheath 2 is greater than the internal diameter of main transmission pipe 1, as the maximum outside diameter of the sheath 2 big 0.3mm of internal diameter than main transmission pipe 1.Because the largest portion of sheath 2 is an acrylonitrile-butadiene rubber, so sheath 2 can be well secured to the arbitrary position in the main transmission pipe 1 and not be subjected to displacement the vibration in the time of weakening spindle drive greatly again simultaneously.
The internal diameter of sheath 2 is greater than the external diameter of final drive shaft 3, as the internal diameter of the sheath 2 big 0.1mm of external diameter than final drive shaft 3.
Be evenly distributed with a plurality of sheaths 2, the axiality in the time that spindle drive can being guaranteed on the final drive shaft 3 of the present utility model.
The high die casting of sheath 2 inner employing copper based powder metallurgy materials of the present utility model forms, because the self-lubricating property of copper based powder metallurgy material is good, need be stained with the spot lubrication oil during therefore except installation, in use must not add any lubricating grease again, can guarantee the whole greasy property of main shaft simultaneously yet.
