Utility model content:
Goal of the invention of the present utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of reasonable in design is provided, easy for installation, the low and efficient angle grinding machine of production cost.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of improved angle grinding machine, comprise motor, motor cover, casing, head capsule, motor shaft, cone pinion, large bevel gear, gear-box, output shaft and emery wheel, wherein, described motor is fixed in described motor cover, described motor cover is arranged in described casing, described cone pinion and large bevel gear are arranged in described gear-box, described cone pinion is arranged on described motor shaft, described emery wheel is arranged on described output shaft, described cone pinion engages with described large bevel gear and drives the described output shaft rotation being fixed on described large bevel gear, then drive described emery wheel rotation, motor is asynchronous machine, described motor is fixed on the electric machine assembly forming in described motor cover and is directly set together with described head capsule.
Also comprise bearing and bearing block, described bearing is arranged on described bearing block and with described motor shaft and coordinates.
Also comprise a sealing ring, described sealing ring is arranged between described gear-box and described bearing.
The fluted disc vertical direction of described cone pinion arranges, and the fluted disc horizontal direction of described large bevel gear arranges.
The utility model has the following advantages with respect to prior art tool:
1, owing to changing traditional series excited machine into asynchronous machine, asynchronous machine is that motor is closed, effectively solved the dustproof problem of motor, and asynchronous machine does not have carbon brush, substantially realizing zero dimension protects, very easy to use, effectively extend service life, in addition simultaneously, can also realize easily high rotating speed, in the time of high speed low torque, running efficiency is high, and in the time of low speed, has high torque (HT), has improved widely operating efficiency.
2, motor is fixed on the electric machine assembly that forms in motor cover and is directly set together with head capsule, has reduced price operation and assembling link, processes conveniently, has improved assembly precision, raising overall performance, and reduced production cost.
3, owing to being provided with sealing ring between gear-box and bearing, can effectively prevent that dust from entering in bearing, extend the service life of bearing.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
Referring to Fig. 1, the improved angle of the one grinding machine providing according to the utility model, comprise motor 1, motor cover 2, casing 3, head capsule 4, motor shaft 5, cone pinion 6, large bevel gear 7, gear-box 8, output shaft 9 and emery wheel 10, wherein, motor 1 is fixed in motor cover 2, motor cover 2 is arranged in casing 3, cone pinion 6 is arranged in gear-box 8 with large bevel gear 7, cone pinion 6 is arranged on motor shaft 5, emery wheel 10 is arranged on output shaft 9, cone pinion 6 engages with large bevel gear 7 and drives the output shaft 9 being fixed on large bevel gear 7 to rotate, then drive emery wheel 10 to rotate, motor 1 is asynchronous machine, motor 1 is fixed in motor cover 2 electric machine assembly that forms directly and head capsule 4 is set together.Owing to changing traditional series excited machine into asynchronous machine, asynchronous machine is that motor is closed, effectively solved the dustproof problem of motor, and asynchronous machine does not have carbon brush, substantially realizing zero dimension protects, very easy to use, effectively extend service life, in addition simultaneously, can also realize easily high rotating speed, in the time of high speed low torque, running efficiency is high, and in the time of low speed, has high torque (HT), has improved widely operating efficiency.Motor 1 is fixed in motor cover 2 electric machine assembly forming and is directly set together with head capsule 4, has reduced price operation and assembling link, processes conveniently, has improved assembly precision, raising overall performance, and reduced production cost.
