Abstract
The utility model relates to a portable safety grindstone machine with soft shaft for building the terrazzo face, comprises a grinding wheel, a speed reducing mechanism, a soft shaft and an electrical machine, and is characterized in that the speed reducing mechanism and the electrical machine are connected by the soft shaft, which can ensure the safety of the operator and the electrical machine. A one level bevel gear is adopted for speed changing and the speed reducing ratio is 2; 1, which can make the rotational speed of the grinding wheel be lower than that of the existing grindstone machine and overcome the defects of large vibration and large noise. A bull gear is fixed by a tapered bearing to be engaged well. The utility model has flexible application, in particular to be suitable for the terrazzo face of the positions, such as the stairway, the step, the handrail, the windowsill, the veranda, the corner, etc., having the advantages of simple structure, convenient operation, high safety and high work efficiency.
Description
The present invention is a kind of portable safe flexible axle stone mill that the terrazzo face is used of building.
The portable stone mill of present domestic use has two types, and a kind of is portable flexible axle stone mill, and its emery wheel directly links to each other with flexible axle, the centre does not have reducing gear, and the rotating speed of emery wheel is exactly a rotating speed of motor, is generally 2850 rev/mins, because rotating speed is fast, vibration is big, and it is not steady to work, cause that noise is also big, contaminated environment, and this stone mill, need when operating personnel use flexible axle is backed on the body, could vertically grind ground, operation is extremely inconvenient, labour intensity is big, and is dangerous.Another kind is back the portable terrazzo machine of ZIMJ-100 type, its emery wheel directly links to each other with 566 watts micro-machine by reducing gear, the centre does not have flexible axle to be separated by, the direct handheld electrical machinery handle of operating personnel, when terrazzo, water easily enters motor and causes faults such as electric leakage, short circuit, electric shock, and is not only very dangerous to operating personnel's person, and motor easily is damaged.Simultaneously this stone mill can not apply external force by from refacing ground, and one to add external force little owing to power of motor, easily overloads and burns out, and is very dangerous to motor.Secondly micro-machine rotating speed is up to 19500 rev/mins, though through three-step gear shift, speed reducing ratio is 7.6:1, and grinding wheel speed still has 2500 rev/mins, and it is fast to have rotating speed equally, and vibration is big, the shortcoming that noise is big.Moreover, all use 203 plane bearings in the reducing gear, power transmission shaft is rocked and cause bevel gear engagement bad, also can burn out motor in case block, and the reducing gear complex structure
Task of the present invention is at the insecurity of original stone mill existence, the shortcoming that vibration is big, noise is big, designs and manufactures a kind of safe and reliable portable safe flexible axle stone mill.
This portable safe flexible axle stone mill is made up of parts such as emery wheel, reducing gear, flexible axle and motors, and emery wheel and reducing gear to be being threaded, and links to each other with flexible axle between reducing gear and the motor.Reducing gear is made of one-level bevel gear speed change, and gear shaft is except that with 203 bearings, and has adopted cone bearing, and this cone bearing does not cause gear shaft to rock under the situation of wearing and tearing yet, guarantees that the bevel gear engagement is good, guarantees the motor safety running, stable working.
Reducing gear adopts one-level bevel gear speed change, and simple in structure, speed reducing ratio is 2:1, and modulus is 2.5, and the large bevel gear axle is fixed with two 203 bearings and one 7204 cone bearing, has guaranteed bevel geared reliability and stationarity like this.After reducing gear slowed down, the rotating speed of emery wheel was 1425 rev/mins, and rotating speed is low, and it is big to have overcome original stone mill vibration, the shortcoming that noise is big.The diameter of emery wheel can adopt 150 millimeters of φ 100～φ.
Motor adopts general ZX-50 type, power at 1.1～1.5 kilowatts motor, and rotating speed is 2850 rev/mins, and the power ratio micro-machine is big, even if stone mill is applying under the situation of external force, also unlikelyly causes the overload of motor and burns out.Link to each other with flexible axle between reducing gear and the motor, when using water mill ground like this, avoided motor, guaranteed operating personnel's the safety and the safety of motor because of faults such as the immersion of water is short-circuited, leaks electricity, electric shocks.Flexible axle adopts 10 millimeters flexible axles of φ, and external diameter is 28 millimeters of φ, long 4 meters.
This portable safe flexible axle stone mill has simple in structure, operate light, safe in utilization, vibrate little, characteristics such as noise is little.Except that dead weight, still can bear 20 kilograms impressed pressure during operation, also can not cause the overload of motor, still can safe handling.Effect height, but 0.8 square metre of flour milling per hour exceed 1/3 than existing, applying flexible, as stair, mark time, handrail, windowsill, balcony, turning etc. locate all can be suitable for.
Description of drawings is as follows:
Fig. 1. be the structure chart of portable safe flexible axle stone mill.
1. being emery wheel, 2. is 7204 cone bearings, 3. is 203 bearings, 4. is bevel gear, 5. is flexible axle, 6. is motor, 7. is reducing gear.
