Rotary Kiln Pinion Wheel Installation Process - China

price: contact company for price

Rotary kiln sec drive pinion is drive section linked with

the gearbox output shaft. Large ring meshes with the rotary

kiln gear which drive the pinion. Pinion installation and

maintenance and the drive shaft alignment is very important.

Installation, to initial positioning tooth tip clearance.

1. Determination of tooth tip clearance

The gear tooth tip clearance c = 0. 25M (where M is

modulus gear). Rolling circle and supporting rolle for long-

term wear and tear due to high temperature can cause the

whereabouts of the rotary kiln cylinder and a large gear

ring radial runout and other factors. Addendum must be

necessary to increase the gap - Recommended for large rotary

kiln c = 0.28M (where the ground round modulus M).

2. Installation process

(1) Find the tooth tip clearance to the initial position.

Length of the bar can be slightly larger than the width of

the pinion gear on the two clenched between the top of the

root.Then complete the localization of small gear.Next

adjust the tooth surface at both ends of the parallel degree

of backlash and as you can. Simultaneous measurement of gear

backlash must meet the requirements.

(2) General pinion ring gear is wider than the body width

of the rotary kiln. Difference should be equal to the width

of the cylinder runout. So should run up and down rotary

kiln position in which it is set to wide-tooth contact

position. To achieve the normal operation of the rotary kiln

thermal process. Large and small gear longitudinal

centerline coincide.

(3) directly to the two gear pitch circle tangent method to

install. Although this approach that the large thermal

expansion of the ring gear. The tire inflation would raise

the kiln shell. It does not result in changes in gear

meshing. The introduction of the rotary kiln is currently


(4) The current small gear installed in two ways: when a

small gear, gear shaft, bearing, steel base has been

installed by the manufacturer together. Direct alignment

with a small gear, the overall installed in place when the

parts in bulk to the scene. It is required with the order

after the assembly. The overall look is in place.

3. the technical requirements of rotary kiln pinion


(l) pinion installation design requirements should allow

the expansion of a large amount of gear. And determine its

pitch to meet the requirements.

(2) adjusting the determination of the size of the gear

tooth tip clearance. It can be 0. 28M or o. 25M + (2 ~ 3) mm

total take (M for the gear module.)

(3) meshing well, the direction of the contact surface

in the tooth should not be less than 50%. In the tooth width

direction of not less than 65%;

(4) Link the pinion shaft and speed reducer shaft

together. Reducer motor coaxial with the main error is not

greater than 0.2mm.
