What is a suspension gearbox or a parallel shaft gearbox?
A type of industrial gearbox is presented that has a structure similar to a straight shaft (helical) gearbox, with the difference that in the suspension gearbox, the output shaft is parallel to the input shaft. This gearbox is suitable for use in mixers, based on the type of design at the end of the output shaft, which is provided as a bearing.
Technical specifications of hanging gearbox (parallel shaft)
Hanging gearbox, which is also called parallel shaft gearbox or parallel shaft gearbox, is one of the medium-sized gearboxes whose torque range is about 80 to 18000 Nm. This feature of the suspension gearbox has led to the inclusion of a wide range of applications in the industry. The structure of this gearbox includes a steel gear at the entrance, which is linked with the electromotor or power supply source and transfers the power to the next gear, which is a large plate gear. If the speed of the gearbox is higher than about 40 rpm, the fourth gear of the suspension gearbox, which is connected to the output shaft of the suspension gearbox, is engaged. When revolutions less than 40 revolutions per minute are needed, two more gears are added in the gearbox to reduce the revolutions and increase the gear conversion ratio, bringing the total number of gears to six gears inside the gearbox.
Based on the output shaft and connection type, the suspension gearbox is divided into the following types:
Based on the output shaft:
Mounting Shaft
Hollow Shaft
Shrink disk
Splined hollow shaft with DIN5480 standard
Hollow shaft with TorqLOC
By connection type:
based
Flange B5
Half flange B14
Parallel Shaft Gearbox
Overhead gearbox or parallel shaft gearbox is one of the most used gearboxes in various industries, the reason for this is the existence of unique features in this gearbox. Among these features is the ability to bear axial and radial loads due to the presence of two bearings on the output shaft of this gearbox, which makes it possible to use this gearbox in different mixers.
Suspended or parallel shaft mixer gearbox
Another feature of this gearbox is the presence of the output of the gearbox parallel to its input, which is the best choice in some installation situations. Another advantage of the hanging gearbox is the possibility of installing it through the earring on the body of the gearbox, which, as a result, allows the gearbox to move in the direction of the output shaft in a very small amount at the time of start and step. Like conveyor belts and material transfer lines, it speeds up cement and steel factories.
Application of hanging gearbox (parallel shaft gearbox)
Suspended gearbox or parallel shaft gearbox are used in most industrial devices due to their appearance and style (eight different modes), which include mixer gearboxes, linear material transfer systems without high shock, crane gearboxes and winch gearboxes. roof, wing mill gearbox, conveyor gearbox, conveyor belt gearbox, rolling gearbox, simultaneous operation system (pair), surface aerator in sewage treatment plants, chemical industries, steel and cement industries.
