What is cranville pinion gearbox or side shaft?
Cranville gearbox, which is also called side shaft gearbox or 90 degree gearbox or hollow shaft gearbox, bull helical gearbox or oblique helical gearbox.
All the aforementioned gearboxes can be provided as a single gearbox or coupled with a motor, which is the motor gearbox or electric gearbox, according to the customer's request.
Technical specifications of cranville pinion or side shaft gearbox
In some industries such as steel and cement, for some reasons, a gearbox with high pressure tolerance and small dimensions is needed. Due to its special design, the helical gearbox is limited in bearing such a load and cannot be used. Also, the direct shaft (helical) gearbox is not a suitable option for use in any place due to the large volume it occupies. Considering this issue, gearbox design experts designed and released a new generation of gearbox called Cranville gearbox or side shaft gearbox. In fact, the Cranville gearbox can be considered a combination of the external properties of the helical gearbox with the mechanical properties of the helical gearbox.
Types of Cranville gearboxes
Shrink disk connection
hollow shaft
Mounting shaft (normal)
Cranville gearbox application
The reason for using cranville and pinion gear, in addition to the appearance, is the greater cross-sectional area of contact between the gears. We know that the greater the contact surface between two objects that apply force to each other, the lower the amount of pressure will be; The result is less frictional force produced with increased energy transfer efficiency.
Cranville gearbox
Cranville pinion gearbox can create an acceptable torque (between 200 and 50,000 Nm) and allows the electric motor to be coupled up to 200 KW.
Also, by changing the installation direction of this type of gearbox, it can also be used to move in the direction of the photo (rear). The conversion ratio of this gearbox (i) varies from 1 to 4 to 1 to 200.
Helical gearbox is one of the most used gearboxes in various industries. These types of gearboxes are used in the following industries:
Oil, gas, petrochemical
Conveyor gearboxes for steel and cement industries
The gearbox of mills in zinc and lead production lines
Marine industry gearbox
Gearbox for food and pharmaceutical industries
Gearbox for opening and closing valves of sedimentation ponds in the water and sewage industry
Ceramic tile gearbox
Gearbox of machines for washing and packaging lines
Conveyor gearbox
Conveyor gearbox
rolling gearbox
Rolling gearbox
Thickener gearbox
Advantages of Cranville gearbox
High pressure telorence
Create high torque
Light weight compared to industrial gearbox
Small dimensions compared to high power
With helical gear
Torque transmission at a 90 degree angle
silent
Low consumption
Without special attention to heat treatment
It has input and output shafts in the form of hollow shafts, shrink disks and mounting shafts
