Function Of Worm And Spur Gears
Spur Gears Producing
The common spur gear: when assembly the problems that the modulus is standard benefit, the strain angle is 20°(regular worth), the tooth thickness of the reference circle is equal to the tooth area width, the pitch angle is 0°, the addendum coefficient is 1 (regular worth), idea clearance coefficient is .25 (regular price), and the modification coefficient is , this involute cylindrical gear is known as regular straight toothed equipment (regular spur equipment).
There are two processing strategies of the gear enamel form.
1 is forming method strategy, which is utilized by the shaped milling cutter that is full compliance with the shape of the equipment tooth place to cut out the tooth profile like milling equipment. The other one is creating method, which is using the equipment cutter meshes with each other with the driven gear to lower out the tooth profile like hobbing and slotting equipment.
The spur equipment producing process is normally includes the equipment blank processing, tooth floor processing, warmth treatment and the finish machining of the tooth floor. In the plan approach, we adopt a lot of diverse procedure plan in accordance to the different equipment framework, precision quality, generation batch and surroundings.
one. The form of the equipment blank: forging, bar materials, or casting
two. Tough process：remove the further margin
three. Semi-finishing method: lathe, gear hobbing, equipment slotting
four. Warmth treatment: quenching and tempering, carburizing, quenching，high frequency induction warmth quenching of the tooth floor
five. Finishing approach: benchmark ending, equipment teeth condition finishing
