Introduce The Deceleration Transmission Device Of A Rotary Drilling Rig

There are various types of deceleration transmission devices used on rotary drilling rigs. For lightweight engineering pile driving devices with lower power, tooth boxes, power selection boxes, and gearboxes with similar size and structure to those of cars and tractors are used. In this device, in order to change the speed of the winch or turntable, a car or tractor tooth box is often set up, and the rotary drilling rig is installed on the tractor.

In many high-power devices, there is a tooth box, which becomes an important part of the winch. A reducer is a separate transmission device for a single motor, dual motor reducer, and turntable.

The chain transmission device is mainly used in the pile driving project of rotary drilling rigs, with multiple rows of chains, because it can reduce the pitch and profile size of the chain transmission device, while also increasing the transmission power. The reducer is a gear transmission device, which is enclosed in a housing filled with engine oil. The use of a single motor or dual motor reducer depends on the transmitted power and the number of motors.

A single motor reducer consists of the following components: a housing with a cover, an active shaft with herringbone spur gears, and a passive shaft; Connect the coupling of the motor shaft and the sprocket that drives the winch to rotate. The dual motor reducer consists of the following components: cast steel casing and cover; There are two active shafts with a herringbone spur gear and a motor shaft adapter; Two active shafts with herringbone spur gears and connecting motor shaft adapters; A passive shaft with herringbone spur gear and a sprocket for driving winch rotation.
