Titanium powder metal injection molding micro modulus gear

As a mechanical transmission component, the gearbox has been widely used due to its high transmission efficiency, compact structure, stable transmission ratio and long life. Large gearboxes are widely used in motors and are often used in wind turbines. Their main function is to transmit the power generated by the wind wheel under the action of wind to the generator and increase its speed. This type of gearbox is used to increase the speed. Micro gearboxes are also used in children's toys. By reducing the speed of high-speed motors, this type of gearbox is used to reduce speed.

The main characteristics of planetary gearbox transmission are small size, large load capacity and stable operation. Therefore, the micro gearboxes used in children's toys are mostly planetary gearboxes. The interior of the planetary gearbox is composed of multiple small gears that mesh and transmit each other. The rotation axis of the gears in most planetary gearboxes is fixed. For example, in mechanical clocks, although all the gears on them are rotating, their rotation centers are often installed on the housing of the gearbox through bearings. These fixed-speed gears are duplex gears, that is, the end faces of two gears with different numbers of teeth are connected together and rotate simultaneously around the same shaft. It is precisely because of this gear with different numbers of teeth that it plays the role of deceleration and acceleration.

The greater the difference in the number of teeth between the upper and lower gears of the duplex gear, the greater the proportion of its acceleration or deceleration. Of course, the greater the difference in the number of teeth between the upper and lower gears of the duplex gear, the larger the area occupied by a single gear. For a gearbox with a very small total volume, the smaller the number of duplex gears it can accommodate, in order to maximize the use of the volume of the gearbox, maximize the speed change of the gearbox, and maximize its transmission efficiency, the existing technology only optimizes the arrangement of the duplex gears and the tooth ratio of the upper and lower gears of the duplex gears, and does not improve other structures of the duplex gears and other structures of the gearbox. Therefore, no matter how it is optimized, its transmission efficiency and speed change can only reach a certain level and cannot break through its limit. Moreover, the volume of the gearbox of this structure cannot be very small.
