TCG Series: Non-backlash Rack and Pinion(13)
An evolved gear system. Please take a look at this innovative mechanism that is unlike anything before. By combining a pinion equipped with roller pins that achieve rolling contact with a high-performance rack arranged in a straight line with trochoidal tooth profiles or a high-performance ring arranged in a curved shape, we realize rotation-linear motion through complete rolling. This enables non-backlash, high-precision positioning and agile motion performance.

Index (Indexing Equipment) Implementation Case Studies(8)
Case Studies of Indexing (Dividing) Equipment There are dividing devices that perform periodic and intermittent operations of one-directional stop - positioning - stop, and devices that convert linear motion into rotary motion for operation. As for cam-type intermittent dividing devices, there are three types: roller gear cam, parallel cam, and barrel cam. Within one rotation of the input, there is a section for dividing the output shaft (dividing angle) and a section where the output shaft stops (stop angle). In the stop section, while the input shaft is rotating, the output shaft does not rotate, allowing for positioning even with induction motors and the like. (In a four-part dividing device, when the input shaft completes one rotation, the output shaft rotates 90 degrees.) On the other hand, cam-type dividing devices set the number of divisions per movement by determining the amount of movement of the output shaft based on the curvature (shape) of the cam that engages with the linear motion of the piston. Indexing devices are widely used in base machines such as rotary automatic assembly machining machines and automatic packaging machines, which require multi-step operations, as they allow for multi-part division (such as 4-way or 12-way division).

Examples of "ball deceleration devices"(5)
An example of a "ball reducer" A ball reducer is a type of speed reducer that features a non-backlash mechanism, solving the issues associated with gear-based reducers. Instead of gears, it uses steel balls as rolling elements to transmit power through continuous rolling contact. By applying preload to the power transmission section (engagement area), it achieves zero backlash. This structure allows for power transmission with zero backlash through the use of steel balls, enabling smooth power transfer without increasing friction. The fundamental concept is also effective in applications such as ball bearings, ball screws, and linear guides.

Examples of "thin and lightweight reduction gears"(2)
This is an ultra-thin differential gearbox that features two robust and precisely crafted trochoidal gears, arranged oppositely inside rollers positioned on the circumference, and outputs through a clever pin-and-hole mechanism supported by cross roller bearings, boasting high reliability.
