Timing Belt The Installation Must Be Kept Dry Before Use
Jun 22, 2017

What are the characteristics of the rubber used in the belt?

The timing belt is a new type of belt with a tooth-like structure, a set of gears, sprockets and belt drives. From the back, strong layer, with teeth and with tooth cloth layer composition (cast polyurethane belt with no cloth layer).

The 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 at work and transmit power. It is composed of a piece of adhesive with a whole, to transmit stress and protect the strong layer, in the drive to withstand shear stress.

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

Bulk rubber is generally used with neoprene, 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 with semi-reinforcing furnace black.

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

(2) Remove the old 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 belt replacement.

(4) clean the belt and pulley, should be wiped with a little easy to wipe the liquid, in the detergent soaked or detergent cleaning the use of cleaners are not desirable; to remove the oil and dirt, with sandpaper or with sharp Object scraping, obviously is not desirable. The 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 about the belt, especially the synchronous belt drive is running.

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

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

(9) Tighten the center of the drive until the tension gauge measures the 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 belt performance, it is important to ensure that all drive parts are tightened.

(11) Start the device and observe the belt performance to 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 belt or bearing asymmetry, or lubrication is not correct.

The maintenance of the timing belt

(1) The belt should not be twisted and drastically bent, the minimum bending diameter of the 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) stored at room temperature, 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 shelf.

(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.
