Spur gear shaft forging high quality large diameter Ball Mill

Overview of Spur Gear Shaft

Spur gears are a type of cylindrical gear with straight teeth that are parallel to the axis of rotation. When two spur gears mesh together, they can transmit rotational motion from one shaft to another, often changing the speed or torque in mechanical systems.

A Spur Gear Shaft is an integral component in the assembly of spur gears. It serves as the supporting element for the gears and transfers the load from the gears to the frame or housing of the machine. The shafts are designed to withstand bending and torsional stresses caused by the forces exerted by the gears during operation.

Application of spur gear shaft in ball mill

The ball mill is usually driven by an electric motor, which transmits power to the spur gear shaft through a reducer. These gear shafts then transmit the rotating motion to the large gear ring of the ball mill or are directly connected to the cylinder, thereby driving the rotation of the ball mill cylinder.

The gear shaft must not only bear the torque from the motor, but also support the radial and axial loads generated during the operation of the ball mill.

Due to the harsh working environment, including dust, temperature changes and other factors, the spur gear shaft needs to use wear-resistant materials, and appropriate heat treatment to improve its service life.

Production process of Spur Gear Shaft

Forging

The blank is heated to a plastic state and then die forged on a forging hammer or press to form the rough shape of the gear. Forging can improve the internal structure of materials and improve mechanical properties.

Rough Machining

The roughing of the spur gear shaft is an important step in the manufacturing process, which lays the foundation for the subsequent finishing. The purpose of roughing is mainly to remove most of the excess material, so that the workpiece is close to the final shape and size, while improving the internal stress distribution of the material.

 Heat treatment

Quenching and tempering are usually included to obtain the desired balance of hardness and toughness, ensuring that the gear has sufficient strength and wear resistance.

Finishing

The finishing of the spur gear shaft is a key step that takes place after the roughing is completed, aiming to ensure that the gear shaft meets high precision and high quality standards. Finishing not only improves the dimensional accuracy, shape accuracy and surface finish of the parts, but also ensures the correct fit between the gear and the shaft and the smooth operation of the entire transmission system.

Precision turning or grinding of the outer diameter, inner hole and end face of the gear to ensure the accuracy of the assembly size.

Surface treatment

Galvanizing, chrome plating, blackening or other anti-corrosion treatments may be performed, as well as surface hardening treatments such as nitriding, carburizing, etc., to enhance the corrosion and wear resistance of the gear.

Package of Spur Gear

Oiling or Coating: Applying a thin layer of rust-preventative oil or another protective coating can shield the surface from moisture and contaminants.

Packing: fumigation-free wooden case customized according to product size. If necessary, a steel frame will be welded to the outside of the wooden box to assist the operation of the forklift truck.
