When an object requires circular motion on a smaller track, a centrally located motor efficiently drives it. However, as the diameter increases, greater friction and higher torque demands arise, leading to complex and costly control. The solution to this challenge?
The circular arc rack. By placing the pinion on the output shaft of a reduction motor, the circular arc rack provides a highly efficient alternative. This innovative design significantly reduces the diameter difference between the moving track and the pinion, thereby minimizing output torque requirements and enhancing overall controllability.
A stair lift gear rack is an important component of a stair lift system, which is used to convert rotational motion into linear motion, enabling the stair lift to move up and down along the stairs. Here is a detailed introduction:
Features：High-precision tooth profile: The tooth profile of the stair handrail rack is usually processed with high precision. It has a high level of accuracy to ensure good meshing with the matching gear, enabling smooth and stable movement and reducing jams and noise.Good wear resistance: Since the rack will frequently come into contact with and rub against the gear during use, it needs to have good wear resistance to extend its service life and reduce maintenance and replacement costs.Customizability: According to different stair design and usage requirements, the stair handrail rack can be customized, including customization of length, width, height, tooth profile, material, and other aspects to meet various special requirements.
Structure and Working Principle：
Structure: It consists of a straight row of equally spaced teeth, similar to a spur gear but in a linear form. It works in conjunction with a pinion, a small cylindrical gear that meshes with the gear rack.
Working Principle: As the pinion rotates, it drives the gear rack to move in a linear direction. In a stair lift, the rotation of the pinion is usually driven by a motor. As the pinion rotates, the gear rack moves along the track of the stair lift, causing the lift seat and the rider to move along the track, thus achieving the upward and downward movement of the stair lift.
Advantages
Simple Mechanism: It has a relatively simple structure, which is easy to manufacture, install, and maintain. Large Load-Carrying Capacity: It can withstand large loads, making it suitable for carrying passengers and heavy objects.Unlimited Length: There is no strict limit on the length of the gear rack. By connecting multiple segments end-to- end, it can meet the needs of stair lifts of different lengths.
Applications
Stair handrail racks have a wide range of application scenarios, including residential building stairs, food production, production lines, aviation equipment, transport vehicles, pharmaceutical manufacturing, and the textile industry. The following are examples for each of these points:
Most of our OEM customers usually send their drawings, if you have special request, send us your drawing or send us sample it is also OK！！！
