Introduction

Pinion stand is core drive parts in the field of metallurgy, transfer torque, ensure the synchronous operation of machine, widely used in steel rolling , billet processing , non-ferrous metal rolling .etc of metallurgical industry, it‘s used in bad working conditions. The pinion stand has the characteristics of smaller volume,lighter weight, larger torque,higher reliability, it has a high level of technology in the country and world.

Introduction of basic types

The pinion stand are classified into eight size according to center distance,every size has two types according to different loading. Product marking methods are as follow：

Example 1：Product with 900 center distance,high loading,Steel feeding direction L mark CLZ900H-L

Example 2：The specific classification of pinion stand size 900

21Pinion

• Material is 18CrNiMo7-6，carburizing and quenching

• Grade of accuracy is above 6 grade .

• Gears are made out of high quality alloy steel both sides are ground, gear

modification

Attended mode

• Shrink fit on two part

• The safety factor of the transmission torque is high

• Convenient assembly

Gear mesh

• Guaranteed accuracy using eccentric sleeve

• Ensure the pinion gear for moderate

Casing

• Welded box，all welds to have full depth penetration

• It used plate Q235B, bearing box used casting

• FKM combined with our accumulated plentiful experience is used to design Casing

Seal components

• It does not need to be replaced for labyrinth seal

• Low risk of oil spills because it has large space for return oil

Bearing

• Adopt international famous brand bearing, the life-time is designed according to

standard ISO281/16281.

Attended mode

1) Input of pinion stand connected with motor (or main reducer) by coupling

2) Output of pinion stand connected with rolling by coupling

Lubricating system

Pinion and bearing are used forced lubrication，customer need buy oil station for normal operation of pinion stand，

and circulation，filtration，cooling.

Selection guide

Calculation Example

Known criteria

Prime mover is motor

Motor power: P=10000Kw

Input speed: n=36rpm

Driven machine is rolling ,center distance is 900mm，Steel feeding direction is left

Duty: 24h/day

Requirements:Calculation of the type,size and Add-on Pieces of pinion stand

1. Calculated size of the pinion strand

Calculated center distance of pinion stand according to working machine

2. Calculated type of pinion strand

① Calculation of the Nominal pinion stand Power Rating

P=10000

② Calculation of the Nominal pinion stand Torque(rating Torque)

T=9.55× =2652 kNm

③ Determination of Steel feeding direction

Attached:Discriminated method for Steel feeding direction

④ Determination of pinion stand Size

Selected from table 1,table 2: type CLZ900H-L

Pinion stand type:CLZ900H-L

3. Determination of pinion stand Dimension

The pinion stand dimension is given in table.

4. Determination of the lubricating system and Add-on Pieces

The pinion stand adopts forced lubrication, Determination of NGC pinion stand standard layout according to the table given in table
