The following are various important factors that depend on the selection of a belt drive:
The speed of the driving shaft and the driven shaft
Reduction ratio
Transmission power,
Center distance between shafts
Active driving needs,
Axis layout
Available locations, and
Terms of Service.
Application of belt drive
Belt drives are widely used in the following occasions:
The belt drive is used to transmit power.
Belt drives are used in the milling industry.
Belt drives are used in conveyors.
Drive the drafting roller and other rolling elements on a single delivery stretching machine.
Drive the opening roller, friction drum and threading roller on the friction spinning machine.
Drive to the rotor on the rotor spinning machine.
The main drive on the wire drawing machine.
Drive to the creel drum of the high-speed stretching machine.
Advantages of belt drive
The advantages of belt drive include:
The belt drive is cost-effective. The new belt transmission efficiency can reach 95-98%
They are easy to use
Belt drive does not require parallel shafts
Their maintenance costs are low
They come with overload and jam protection
Different speeds can be obtained by stepping or tapered pulleys
When the distance between the shafts is large, the belt drive is the most economical choice
Eliminate noise and vibration
Load fluctuations are damped, extending the life of the machine
Release the belt tension to activate the clutch action
Disadvantages of belt drive
However, belt technology also has certain disadvantages of belt drives. all these are:
Belt drive is not compact
Speed limit is about 35 meters per second
Compared with other modes of power transmission, their service life is short
Generally, its operating temperature is limited to -35 to 85°C
The angular velocity of the belt drive is not constant. This can cause the belt to stretch, slip and wear
Its limited power transmission is up to 370 kW, which increases heat accumulation
Belt drive usually puts a heavy burden on shafts and bearings
In order to compensate for wear and stretch, they also need an idler or some center distance adjustment
Speed ratio changes due to belt slippage
