Working principle of rack and pinion transmission:
The rack and pinion mechanism is composed of gear and rack. The rack and pinion transmission converts the reciprocating linear motion of the rack into the rotary motion of the gear, or converts the rotary motion of the gear into the reciprocating linear motion of the rack. Gear transmission is used to transmit motion and power between any two shafts, and is the most widely used mechanical transmission in modern machinery. Its peripheral speed can reach 300m/s, the transmission power can reach 105KW, and the gear diameter can be less than 1mm to above 150m.
Plastic gear rack transmission has the characteristics of large power transmission and effective gear transmission, which can ensure a constant transmission ratio, can transmit motion between two shafts at any included angle, and stable operation, high reliability and long service life. It is widely used in industrial robot arm grabbing mechanism, factory automation rapid transplanting machine, cutting machine, welding machine, CNC machine tool, machining center and other fields. Nylon helical gear rack, plastic helical gear rack and pinion can be made in our shop.
Advantages of the plastic gear rack and pinion:
The plastic gears have low friction coefficient, good wear resistance, high transmission efficiency, and can be operated without or with low lubrication.
The plastic helical racks and racks have good elasticity, shock absorption and anti-impact, low noise during operation, and stable transmission.
Corrosion-resistant, rust free, can be operated in corrosive medium.
Disadvantages of plastic gear rack and pinion:
Mildly low, so the transmission load cannot be too large;
The operating temperature is not high, and the thermal conductivity is much lower than that of metal, which is not conducive to heat dissipation.
The coefficient of thermal expansion is large, and it will swell after absorbing water and oil. When the temperature and humidity of the environment change, the dimensional stability is poor.
Common materials of nylon gear rack and pinion:
PA6 \ PA66: suitable for medium or low load, under 80°C temperature, working under low or no lubrication conditions.
PA610.PA9 and PA1010: the same as above, it can work under moderate fluctuations.
Cast nylon: suitable for the manufacture of large gears.
Reinforced nylon: suitable for high load and high temperature applications, high transmission efficiency, and lubricating oil should be added during operation.
PC: lubrication should be added when running at high speed.
Modified polyphenylene ether: precision gears that can be used in hot water or steam
Polyimide: gear suitable for long-term operation at 260°C
Reinforced polyester: suitable for high or medium and low load, working under 150°C, under lubricating conditions
Polyphenylene sulfide: suitable for gears with medium and high load and no lubrication
UHMWPE: suitable for medium and low load, oil-lubricated gears below 240 degrees
Cloth phenolic: suitable for low load gears
