Product features

Helical gears are round metal disks with teeth cut around the circumference. In order for the gear to qualify as a gear, the tooth must be cut so that they run perpendicular to the gear’s face. Helical gears are the simplest design of gear produced. They are usually used for the transmission of rotary force. For example, if two shafts are parallel to one another, and one is spinning, a helical gear can help to transfer that force onto the other shaft. Helical gears usually have an operating efficiency of 98% to 99%.

LEITE Best Seller 2018 Planetary Gear for Rotating Machine

A Gear Or Cogwheel Is A Rotating Machine Part Having Cut Teeth, Or Cogs, Which Mesh With Another Toothed Part To Transmit Torque. Geared Devices Can Change The Speed, Torque, And Direction Of A Power Source. Gears Almost Always Produce A Change In Torque, Creating A Mechanical Advantage, Through Their Gear Ratio, And Thus May Be Considered A Simple Machine. The Teeth On The Two Meshing Gears All Have The Same Shape.[1] Two Or More Meshing Gears, Wor ept In A Sequence, Are Called A Gear Train Or A Transmission. A Gear Can Mesh With A Linear Toothed Part, Called A Rack, Thereby Producing Translation Instead Of Rotation.

Construction machinery gear parts for planetary gear 
The wor ept principle of gear:
1. transmission of power
2. changing movement of speed
3. change the direction of movement
Gear Classification :
1. gear
2. bevel gears
3. bevel gears
4. Turbo
5. rack and pinion
6. planetary gear

Gear transmission advantages and disadvantages
Advantages more stable Disadvantages 1.Requir high precision the manufacture and installation 
2. high efficiency
3. reliable
4.compact 2.the manufacture and installation of high precision
5.long service life

Gear technical requirements
1. Transmission of motion accuracy
2. Balance of transmitting motion to reduce shock and vibration and noise, that calls for limits on gear turns the instantaneous speed of change
3. Load distribution, uniform gear tooth contact is required when you want to, make the gears in the transmission of power without due to uneven contact surfaces of contact stress load is too large, causing premature wear of tooth surface
4. Rationality of transmission side gap
Gear Failured:
1. wear of tooth surfaces
2. tooth surface gluing
3. fatigue pitting
4. tooth broken
5. tooth surface plastic deformation
Gear maintenance posted scholar:
1. we should put lubrication on gear when gear start to work , Make gear on a good work condition
2. Gear wor ept after we should check whether between pars exist friction ,such as parts extrusion of noise, if exists words, should do appropriate adjustment to parts
3. During gear opration ,should cleanup waste oil , completely cleared dirt, with clean of gauze for wipe,
4. Smearing oil and lubricants on gear, always guarantee gear wor ept in a clean and lubrication of environment
