What are the gear meshing transmission conditions and working characteristics?
(1) driving conditions
A pair of gear meshing transmission must meet the following conditions.
The ratio of this pair of gears is the same.
The toothed angles (pressure angles) of these two gears are equal.
If the torque is a bevel gear, the bevel angles of the teeth should be equal, one is left rotation, the other is right rotation.
Keep the meshing center distance of the two gears at A value, i.e., A = 1/2m(Z1+Z2).
(2) working characteristics
The working characteristics of gear meshing drive are as follows.
The gear transmission is a pair of gear meshing transmission to transfer torque force.
Parliamentary gear drive ratio fixed.
Torque gear drive has high efficiency and long life.
The transfer power and operating speed range is wide.
Transaction gear transmission mechanism is compact.
The lack of methangear transmission is due to the high working noise, which cannot be used for long distance transmission work, and the high cost of gear manufacturing.
