Product Description

Customizable Precision Machining Curved Hobbed Spur Pinion Stairlifter Gear Rack for Staircase Handrails and Different Scenes

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:

Residential Building Stairs：In detached villas, wooden stair handrail racks are commonly installed. They offer safety by preventing falls and complement the villa's decor, creating a cozy, upscale ambiance.

Food Production Production Line：On cookie production lines, metal handrail racks are used in conveying equipment. They precisely control the conveyor belt, ensuring smooth transport, avoiding jams, and maintaining production efficiency and food quality. Aviation Equipment：In aircraft boarding bridges, handrail racks are essential. They must be strong and stable to support passengers and function in all weather, providing a safe passage. Transport Vehicles：Large logistics trucks have foldable stairs with metal handrail racks. These racks enable easy access for loading and unloading, bearing human weight and climbing forces to ensure safety. Pharmaceutical Manufacturing：In pharmaceutical packaging workshops, conveyor line stair - type lifts use stainless steel handrail racks. Their corrosion - resistance and ease of cleaning meet strict hygiene standards, ensuring equipment stability and drug safety. Textile Industry：In textile mills, handrail racks on material hoists are made of dust - resistant, smooth - surfaced materials. They combine strength with easy cleaning, safeguarding operators during frequent use.
