400 – 600 mm Timing Belt Tensioner Pulley Construction Machinery

Introduction
Tensioner is a commonly used holding device on belt and chain transmission systems. It is characterized in that the belt and chain can have proper tension during the transmission process, so as to prevent the belt from slipping or avoid tooth skipping and tooth loss. Drag out.
Or prevent the chain from loosening and falling off, and reduce the wear on the sprocket and chain. The structure of the tensioner is various, which generally includes a fixed structure and an elastic automatic adjustment structure. The fixed structure mostly uses a fixed and adjustable sprocket to adjust the tension of the belt and the sprocket. Automatic rebound controls the tension of belts and chains. Domestically adjustable chain tensioners mostly use spring structures, while foreign tensioners mostly use rubber components.

Model：

Parameter:
1. RER 40 consists of an elastic rotating shaft and a grooved rocker arm welded to the rotating shaft.
2. REMER 40 consists of a rotating shaft and a slotted rocker arm, which allows the shaft to be adjusted, so the power of the cleaner can be adjusted. Torsion angle ± 30 °. Operating temperature from -40 ° C to + 80C.
3. RERU40 This elastic component allows the adjustment of the cleaning blade tilt angle (total 30 °) and adjusts the mounting angle of the base component (it has been set to 120 ° in total / 5 positions with 30 ° in between). The RERU 40 with shaft adjustment is already equipped with the PR 40 pre-loading system, which can be used to simplify installation and fix the handle at a predetermined height. Torsion angle ± 30 °. Operating temperature from -40 ° C to + 80 ° C.
4. The RE series elastic tensioning device generates a cleaning and tensioning pressure on the conveyor belt scraper which is continuous and prevents rapid wear of the belt, which can remove small adherent particles.
5. CEA and CEAP are basically elastic supports, combined with other specially designed special components as required. To facilitate installation, removal and adjustment, CEAP is equipped with a pre-loading system ().
6. CET and CETP are basic elastic supports for use with square parts. CETP is equipped with a preload system (?). Torsion angle ± 30 °. Operating temperature from –40 ° C to + 80C.
7.AR-T, AR-P, AR-F, AC-T, AC-P belt cleaner elastic components

Application:
Tensioners are widely used in vehicles, agriculture, wood processing, mining machinery, industrial transportation, construction machinery, food processing, playgrounds and outdoor buildings.

Advantage:
1. The elastic tensioning device generates a cleaning and tensioning pressure on the conveyor belt scraper that is continuous and prevents rapid belt wear, which can remove small adherent particles.
2. Prevent rapid wear of scraper

3. Effectively absorb the beat of the belt

4. Make sure the surface of the belt is clean
