Timing Belt Heat Resistance, Fatigue Resistance, Water Resistance

What are the characteristics of the rubber used in the Timing Belt?

The timing Timing Belt is a new type of Timing Belt with a tooth-like structure, a set of gears, sprockets and Timing Belt drives. It consists of back, strong layer, toothed and toothed cloth (cast polyurethane Timing Belt without cladding).

The Timing Belt is a protective layer that firmly holds the strong layer at the pitch line, which is subjected to tension, bending, and stress to the strong layer.

The teeth are engaged with the teeth of the pulley during operation to transmit power. It is composed of a piece of adhesive with a whole, the transmission stress and protection of the strong layer, in the drive to withstand shear stress.

Synchronous Timing Belt with the performance requirements of the material, the most important thing is to make the rubber and polyester fiber or polyester fiber cord firmly bonded, with good flow during the burning period to ensure that teeth. Another rubber but also heat, fatigue, water, ozone resistance, oil resistance, weather resistance, there is sufficient plasticity.

Bulk rubber is generally made of chloroprene rubber, which requires high hydrogenated nitrile rubber (HNBR). Formulation can be used between the white direct bonding system, so that the bonding strength to meet the requirements. Carbon black selection semi-reinforced furnace black.

(1) Turn off the power, remove the protective cover, and loosen the mounting bolts of the motor. The mobile motor makes the Timing Belt loose enough to remove the Timing Belt without prying, and do not pry the Timing Belt.

(2) Remove the old Timing Belt and check for abnormal wear. Excessive wear may mean that there is a problem with the design or maintenance of the drive.

(3) Select the appropriate Timing Belt replacement.

(4) clean the Timing Belt and pulley, wiping the cloth should be a little easy to wipe the liquid, in the detergent soak or use detergent to wash the Timing Belt are not desirable; to remove oil and dirt, with sandpaper or with sharp Object scraping, obviously not desirable. The Timing Belt must be kept dry before installation.

(5) check the pulley for abnormal wear or crack, if the wear and tear, you must replace the pulley.

(6) Check whether the pulley is linearly symmetrical. The pulley is linearly symmetrical with respect to the operation of the Timing Belt, especially the synchronous Timing Belt drive.

(7) Check the rest of the transmission components, such as bearing and sleeve symmetry, durability and lubrication.

(8) to install a new Timing Belt on the pulley, never pry or force too much.

(9) Tighten the center of the drive until the tension gauge measures the Timing Belt tension as appropriate. Turn the wheel by hand and retract the tension.

(10) Tighten the motor assembly bolts to correct the torque. Since any change in the center distance of the drive during operation will result in poor Timing Belt performance, it is important to ensure that all drive parts are tightened.

(11) start the device and observe the Timing Belt performance, see if there is abnormal vibration, listen to whether there is abnormal noise. It is best to turn off the machine, check the bearing and motor conditions; if it feels too hot, may be too tight Timing Belt or bearing asymmetry, or lubrication is not correct.

Timing Timing Belt maintenance

(1) The Timing Belt should not be twisted and drastically bent, with the minimum bending diameter of the Timing Belt.

(2) in the storage and transportation process, to avoid direct sunlight, rain and snow leaching; to prevent acid, alkali, organic solvents, water vapor and other products affect the performance of material contact;

(3) at room temperature storage, the general temperature is

And at least one meter away from the heat source.

(4) during storage to prevent excessive weight and deformation, shall not be stacked pressure, shall not be directly on the ground, should be hanging on the shelf or flat on the shelves.

(5) The finished product shall be stored and transported in a dry and ventilated environment, and the finished product shall be treated with rust;

(6) with the transmission device should be added protective cover, and to ensure ventilation and sewage.
