Abstract
The invention relates to an angle grinder which comprises a gearbox, a rotor, a rotor front bearing, a rotor rear bearing, a bearing box, an output shaft, an output shaft bearing and a lock pin, wherein one end of the output shaft is fixedly connected with a grinding wheel piece of the angle grinder by penetrating through the bearing box, and the other end is fixedly connected with a big gear; the big gear is meshed with a small gear fixed on a rotor front end shaft; the outer side of the rotor rear bearing is connected with a wild shield and a stator; both the wild shield and the stator are sleeved on a rotor front end shaft; elastic oil seals are additionally arranged between the rotor front bearing and the rotor front end shaft and between the output shaft bearing and the output shaft respectively; O-shaped seal rings are respectively sleeved on the lock pin of the gearbox and an end cover opening of the bearing box approaching to the side of the gearbox; a bearing aluminum sleeve is sleeved on the periphery of the rotor rear bearing; and a dust preventing ring is arranged between the rotor rear bearing and a rotor rear end shaft. The invention can effectively prevent dust, dissipate heat, reinforce the seal performance of the gearbox and prolong the service life of the bearings and the durability of gears.
Description
Technical field
The present invention relates to a kind of electric tool, relate in particular to a kind of angle grinding machine.
Background technology
Existing angle grinding machine gear-box poor sealing, used lubricating oil can only be used the butter of solid shape etc., and can not use liquid oils, causes foreign to be invaded easily like this, and lubricating oil is easily revealed, and bearing is low service life, and the gear durability is low; And the angle grinding machine is in running work, and rotating speed is very fast, and it is very big to gather heat, and thermal diffusivity is not fine, also has in the operation engineering, and dust enters bearing by housing easily, has lowered the service life of bearing greatly.Therefore need provide a kind of new technical scheme to solve the problems referred to above.
Summary of the invention
The technical problem to be solved in the present invention provides a kind ofly can effectively prevent dust, dispel the heat, and strengthens the sealing property of gear-box, improves the angle grinding machine of the durability of service life of bearing and gear.
The technical solution used in the present invention:
The angle grinding machine, comprise gear-box, rotor, rotor front bearing, the rotor rear bearing, bearing housing, output shaft, output shaft bearing and lock pin, described output shaft one end passes bearing housing fixedlys connected with angle grinding machine grinding wheel, the other end is fixedlyed connected with gear wheel, described gear wheel and the pinion that is fixed on the rotor front end axle, the described rotor rear bearing outside is connected with windshield and stator, described windshield and stator all are socketed on the axle of rotor rear end, between described rotor front bearing and the rotor front end axle and add the elasticity oil sealing respectively between output shaft bearing and the output shaft, the lock pin of described gear-box and bearing housing are respectively installed with the O RunddichtringO by on the end cap mouth of gear box side, outer the placing of described rotor rear bearing is socketed with bearing aluminium cover, also is provided with dust ring between described rotor rear bearing and the rotor rear end axle.
The present invention is by between rotor front bearing and rotor front end axle and installed the elasticity oil sealing respectively additional between output shaft bearing and the output shaft, lock pin and bearing housing at gear-box have been set with the O RunddichtringO by on the end cap mouth of gear box side, thereby the sealing that has realized gear-box strengthens, and can use the lubricating oil of liquid state, when work, help the lubricating oil atomizing like this, improve the gear durability, the deficiency that solved that the sealing that original sealing mechanism exists is strong, lubricating oil is easily revealed, bearing service life is low, the gear durability is low.
The present invention also at rotor rear bearing the outer bearing aluminium cover of having placed socket, also is provided with dust ring between rotor rear bearing and rotor rear end axle.So both can dispel the heat, can prevent dust again, thereby improve structural strength, increase the service life of bearing.
Advantage of the present invention is: effectively prevent dust, dispel the heat, strengthened the sealing property of gear-box, improved the service life of bearing and the durability of gear.
