Spur Gear For Mixers

Spur gears are the most widely used gears for parallel shaft power transmission, featuring straight teeth with a zero helix angle. This design eliminates axial thrust during operation, allowing the gears to transmit torque efficiently while simplifying bearing arrangements and reducing system complexity. Known for their high transmission efficiency, ease of manufacturing, and cost-effectiveness, spur gears are an ideal choice for industrial machinery, gearboxes, conveyors, agricultural equipment, and automation systems operating at medium to low speeds.

The spur gear is the most fundamental, cost-effective, and efficient type of parallel shaft gear. It is ideally suited for medium-to-low speed applications with moderate noise requirements and simple bearing support structures. For high-speed operations or where low noise is critical, helical gears should be utilized instead.

Belon is capable of providing tailor made spur gear for mixers from sample to mass production.

The Crucial Role of Spur Gears in Mixers

The spur gear acts as the essential “power behind the scenes” within this mixer. Its functions can be summarized into three core aspects:

Core Function: Speed Reduction and Torque Multiplication

Power Source: Mixers are typically driven by electric motors, which operate at very high speeds under no-load conditions but deliver relatively low torque.

The Spur Gear’s Mission: The concrete mixing drum is extremely heavy, and the resistance increases significantly once filled with aggregate, cement, and water. The spur gear’s role is to drastically reduce the high input speed from the motor while multiplying the torque exponentially.

Result: After passing through the spur gear reduction stage, the output shaft rotates slowly but with immense power. This is sufficient to effortlessly turn the heavy drum, ensuring raw materials like cement and sand are mixed thoroughly and uniformly.

Power Transmission: Changing Direction

In many small mixer designs, the motor is mounted horizontally, whereas the drum’s drive shaft is typically vertical or inclined.

As a parallel shaft gear, the spur gear efficiently transfers the motor’s horizontal rotational power to the drum’s drive shaft. This achieves a smooth transition of power and a change in direction, minimizing energy loss during transmission.

Structural Support: Fixed-Axis Stability

Spur gears feature a simple structure and excellent rigidity, making them highly suitable for environments with vibration and impact, such as small construction machinery.

Inside the mixer, the spur gear is securely fixed within a robust reducer housing. This fixed-axis gear train design ensures stable meshing even under high-speed and heavy-load conditions, reduces slippage, and extends the service life of the equipment.

Forging

When gears need high performance that needs to withstand high loads, high stress, impact loads or fatigue loads, forgings are suggested to use. Forging allows metal fibers to be continuously distributed along the gear profile, significantly improving root strength and fatigue life.

Turning

This is the process of cutting and shaping solid materials into precise parts. It uses tools like lathes, mills, and drills to remove excess material. Machining transforms a simple block of metal into a finished, functional component.

Gear Cutting

Gear Cutting includes all processes to create gear teeth after rough or fine machining. It shapes teeth to ensure smooth and efficient power transfer for performance, strength and cost efficiency.

Heat Treatment

Gears need to be running with two gears or above two gears, that makes them easy to be worn-out. That’s why most types of gears need to be harden through heat treatment.
