Manufacturer's direct cone idle

  Introduction to tapered idler:
The cone-shaped idler is divided into cone-shaped centering idler and cone-shaped centering idler
The cone-shaped idler has wear resistance and long service life
Light weight, small rotation inertia
Reasonable structure and reliable sealing
Excellent corrosion resistance

Characteristics of tapered idler:
Conical idler has extremely high wear resistance, extremely low friction coefficient, and is not easy to wear the belt;
Superior self-lubricating property, no need to inject oil, and it is not easy to get stuck under bad conditions;
Anti static, anti combustion, anti-aging, acid, alkali and organic solvent corrosion;
Can withstand repeated impact and vibration; Operating ambient temperature range: -40 ℃ -90 ℃;
Excellent mechanical performance, light weight, easy installation, no maintenance;
Stable operation and long service life

Application scope:
Tapered idlers are widely used in steel plants, power plants, wharves, coal mines and other transportation industries
They are wear-resistant, impact resistant, anti-aging, noise-free, anti-static, self-lubricating and do not tear conveyor belts, reducing resistance, suitable for long-distance transportation and reducing energy consumption

Processing and production process:
1、 The bearing seat is made of cast iron
Step holes are machined at both ends of the idler steel pipe, and then the bearing seat is press fitted
　　
Its main defects are:
1
Unreasonable labyrinth structure and poor sealing performance; 　　
2
The manufacturing accuracy is poor, and the roundness of the inner step holes at both ends of the idler steel pipe meets the requirements after processing, but the original out of roundness of the steel pipe cannot be eliminated; 3
The weight of the rotating part of the idler is large, resulting in the increase of the rotational inertia of the idler; 　　
4
High labor intensity
　　
2、 The bearing seat is formed by stamping with steel plate material, and then welded to both ends of the steel pipe by carbon dioxide gas shielded welding process
　　
Its main defects are:
1
The sealing performance can not reach the most ideal effect; 　　
2
Irregular deformation during welding will affect the coaxiality of bearings at both ends
　　
In order to solve the disadvantages of the above-mentioned traditional idlers, the new bearing seat of the idlers has good plasticity
Based on the good linear accuracy of the special high-frequency electric welded steel pipe for the idlers (the bending degree of the 6m long steel pipe is no more than 3mm) and the consistency of the circumferential wall thickness, the “ Nylon alloy ” The bearing seat and support ring are directly fitted with the idler steel pipe by interference pressing, which realizes a new idler production process without machining and welding for the inner diameter of the idler steel pipe
The main advantages of this method are:
1
The coaxiality of the bearing positions at both ends of the idler is ensured, and the error is ≤ 0
05mm； 　　
2
The interference press fit of bearing seat and support ring can eliminate about 60% of the out of roundness of the steel pipe, and the radial circular runout of the outer circle ≤ 0
3mm； 　　
3
Rotational resistance ≤ 1N； 　　
4
Noise (at 1000r/min) ≤ 30dB； 　　
5
The manufacturing accuracy of the idler is effectively guaranteed, and the assembly qualification rate reaches 100%; 　　
6
The mass of the rotating part is reduced by 1/3, and the moment of inertia is greatly reduced; 　　
7
The production process is simplified, the labor intensity is reduced, and the work efficiency is improved; 　　
8
The traditional sealing structure is changed, and the long-term normal operation with zero pollution is realized in various harsh environments
