Electric Rotary Hammer Spur Gear Vibro And Impact Hammer Parts For Power Tool

The spur gear in an electric hammer, also known as a spur gear, is a simple and common gear type used to transmit power in the transmission system of an electric hammer. Spur gears are typically used in parallel-shaft transmissions, where the gear axes are parallel to each other. In electric hammers, the main working principles of spur gears are as follows:

• Power transmission: The motor of the electric hammer transmits the rotational motion to other transmission components, such as bevel gears or sprockets, through spur gears, thereby driving the hammering mechanism or drill bit.
• Speed ​​reduction or speed increase: Depending on the design of the electric hammer, spur gears can be used to reduce speed or increase speed. The reduction gear set will reduce the speed output by the motor, while the speed-increasing gear set will increase the speed.
• Parallel shaft transmission: Spur gears are suitable for parallel shaft transmission, which means that the motor axis and transmission axis of the electric hammer are parallel. This design simplifies the structure of the gearbox and makes the electric hammer more compact.
• Meshing principle: The teeth of spur gears cooperate with each other through the meshing principle. The tooth profile shape of the gears allows them to bite together tightly to transmit power.
• Noise and vibration: Spur gears may produce certain noise and vibration when meshing, so the design needs to consider reducing these adverse factors to improve the performance and user experience of the electric hammer.
• Lubrication and cooling: In order to ensure the long-term stable operation of spur gears, appropriate lubrication and cooling systems need to be provided within the gearbox to reduce wear and friction and prevent overheating.

The design of spur gears in electric hammers needs to consider factors such as material wear resistance, machining accuracy, lubrication system, and noise and vibration control to ensure that the electric hammer can work efficiently and reliably. Through these design features, spur gears can play a key role in the transmission system of the electric hammer to achieve effective transmission of motor power.
