庄司歯車エンジニアリング Company Overview

Winches, rack jacks, and reducers that hold loads without power or brakes are suitable for explosion-proof measures! The key points are lightweight, compact, and space-saving!

We have developed and adopted numerous application products equipped with a unique load-holding function (Shoji-lock). <Shoji-lock Product Features> - When rotation is applied from the input side, the output side decelerates and transmits power, but rotation is not possible from the output side, which means it has a self-locking function. In other words, it can hold the load at the desired position without the need for brakes. - Compared to worm gear reducers with the same self-locking function, it is highly efficient. Additionally, while the worm has input and output axes that are perpendicular, our design features input and output shafts that are in a straight line (inline), making it considerably compact, space-saving, and lightweight. - Unlike ratchets or one-way clutches, it can hold the load at any position when motion is stopped, regardless of the direction of rotation. Furthermore, there is no ratchet noise, making it suitable for use in quiet environments. - It has a basic sealed structure (equivalent to IP65), is maintenance-free, and is suitable for explosion-proof areas. - We offer a variety of application products, including gear reducers that utilize this self-locking mechanism, winches, and linear actuators (rack jacks). - Stainless steel versions are also available for cleanroom applications across various models. - There are cases where a switch from small hydraulic jacks is being considered.
