180 Polisher Bevel Gear Kit With Large Transmission Ratio For Stability

180 Polisher Bevel Gear Kit With Large Transmission Ratio For Stability
 

I. Basic Transmission Logic —— Spatial Direction Change of Bevel Gears
Bevel gears are a spatial non - parallel shaft transmission mechanism (the two shafts form a certain angle, usually 90° perpendicular). In the 180 polisher, they undertake two core tasks:
1.Direction - changing Transmission
The horizontal rotational power output by the polisher motor is transmitted to the driven bevel gear (the large gear, connected to the polishing disc shaft) through the tooth surface meshing of the driving bevel gear (the small gear). The power direction is changed from horizontal to vertical (or an inclined angle), driving the polishing disc to rotate.
2.Torque Conversion
Using the transmission ratio of bevel gears, “deceleration and torque increase” or “acceleration and torque decrease” is achieved. The 180 polisher requires the polishing disc to have low speed and high torque. Through the design of a large transmission ratio (the driving wheel is small and the driven wheel is large), the high - speed rotation of the motor is converted into the stable low - speed rotation of the polishing disc, ensuring uniform grinding force.

II. Coordination with the Polisher —— “Precise Control of Grinding Actions”
The core of the polisher is the high - speed rotation of the polishing disc + pressure grinding. Bevel gears precisely control the grinding process by cooperating with the motor, the polishing disc shaft, and the speed - regulating mechanism:
1.Pure Grinding Mode (e.g., Polishing of Metals, Stones)
The bevel gear is directly linked with the motor, and the torque is stably transmitted through fixed - ratio meshing. The rotation speed of the polishing disc is controlled by motor speed regulation (or a gearbox). The involute tooth profile (or circular arc tooth) of the driving wheel ensures stable meshing, and the rotation runout of the polishing disc is ≤ 0.1mm, avoiding uneven grinding marks.
2.Variable - speed Grinding Mode (Adapting to Different Materials)
Some 180 polishers are equipped with a variable - speed gearbox, and the bevel gear set is a part of it. Through a shifting mechanism, the pairing of bevel gears with different numbers of teeth is switched, realizing stepless/step - by - step adjustment of the rotation speed of the polishing disc, adapting to the grinding requirements of different materials such as metals (low speed, high pressure) and wood (medium speed, light pressure).

III. Key Design —— “High Wear Resistance + Low Vibration” for Polisher Adaptation
To ensure the long - term grinding and high - precision grinding of the polisher, bevel gears have these special designs:
1.Material and Heat Treatment
▶Driving Wheel (Small Gear): 20CrMnTi alloy steel is commonly used. After carburizing, quenching + grinding, the tooth surface hardness is HRC58 - 62, and the wear - resistant service life exceeds 10000 hours.
▶Driven Wheel (Large Gear): 45# steel is used for quenching and tempering treatment, and the tooth surface is induction - hardened to avoid overload fracture.
2.Tooth Profile and Precision
▶The Gleason system circular arc tooth bevel gear is adopted. Compared with the straight - tooth bevel gear, the meshing contact ratio is increased by 30%, and the transmission noise is reduced by 10dB, meeting the low - noise requirement of the polisher.
▶The tooth profile accuracy is grade 7 - 8, and the tooth surface roughness Ra ≤ 0.8μm, ensuring the rotation precision of the polishing disc and reducing grinding chatter marks.
3.Assembly and Clearance Adjustment
▶The bevel gear, the motor shaft, and the polishing disc shaft adopt a taper fit + keyway positioning, and the axial runout is ≤ 0.05mm, avoiding gear loosening caused by polisher vibration.
▶The gear meshing clearance is controlled by the shim adjustment method, ensuring transmission efficiency and reducing power loss.

This set of bevel gears is the “power direction - changing hub” of the 180 polisher: it realizes power direction change through spatial vertical shaft transmission, cooperates with the motor and the speed - regulating mechanism, and precisely controls the rotation speed and torque of the polishing disc; with high - wear - resistance materials and high - precision tooth profile design, it ensures the stability and precision of the polisher under long - term and high - pressure grinding. Its design logic reflects “spatial transmission adaptation + working condition demand customization”, and it is the core transmission foundation for the polisher to achieve efficient and precise grinding —— Small gears drive large - scale grinding and support the surface treatment processes in industries such as metal processing, stone treatment, and furniture manufacturing.
