Casters are a common component of mobile equipment and are widely used in industrial, medical and commercial fields. Understanding the basic structure and principle of casters is essential for choosing suitable casters. This article will analyze the basic structure and working principle of casters in detail, and introduce how to choose and maintain casters.
The basic structure of casters mainly includes the following parts:
The wheels are the core components of casters and are usually made of rubber, polyurethane, nylon, cast iron and other materials. Wheels of different materials are suitable for different ground surfaces and use environments.
Rubber wheels are suitable for smooth ground surfaces and provide good cushioning and quiet effects.
Polyurethane wheels have high load-bearing capacity and wear resistance and are suitable for use in industrial environments.
Nylon wheels have high hardness and chemical resistance and are suitable for special environments.
The brackets are used to fix the wheels and connect to the equipment. Brackets are usually made of steel, aluminum or plastic, and are divided into directional brackets and universal brackets.
The directional bracket enables the wheel to move in only one direction and is suitable for occasions where a stable moving direction is required.
Universal brackets allow the wheels to rotate freely, providing greater flexibility.
The bearings are important components between the wheels and the brackets, which determine the rolling performance of the wheels. Common types of bearings are ball bearings, needle bearings, and sliding bearings.
Ball bearings provide smooth rolling and low friction, suitable for equipment that needs to be moved frequently.
Needle bearings are suitable for high-load applications and provide higher load-bearing capacity.
Sliding bearings have a simple structure and are suitable for low-speed, low-load applications.
The working principle of casters mainly relies on the rotation of the wheels and the fixation of the brackets to achieve the movement and positioning of the equipment. Depending on the type of caster, different casters have different working principles:
The wheels of fixed casters can only rotate in one direction and are usually used for equipment that requires a stable moving direction, such as carts and conveyors. Its working principle is similar to the front wheels of a car, ensuring that the equipment moves in a straight line.
The wheels of universal casters can rotate 360 degrees, providing greater flexibility. Its working principle is similar to the front wheels of a shopping cart, allowing equipment to be easily turned and moved.
Braking casters are equipped with a brake that locks the rotation of the wheel, ensuring that the equipment remains stationary when needed. Its working principle is to achieve braking through mechanical or electromagnetic means.
There are several factors to consider when choosing the right caster:
Choose a caster with the right load-bearing capacity according to the weight of the equipment. Generally, the load-bearing capacity of the caster is determined by its material and structure.
Consider the ground conditions and temperature conditions of the use environment. For example, rubber wheels are suitable for smooth floors, while polyurethane wheels are suitable for rough floors.
Choose fixed casters or swivel casters according to the mobility requirements of the equipment. For equipment that requires frequent turning, swivel casters are a better choice.
Maintenance of casters is essential to extend their service life. Here are some basic maintenance tips:
Clean the wheels and brackets regularly to prevent dust and debris from accumulating and affecting the rolling performance of the wheels.
Check the lubrication of the bearings regularly and add an appropriate amount of lubricant to ensure smooth rolling of the wheels.
Check the wear and tear of the wheels regularly, and replace the severely worn wheels in time to ensure the safe use of the equipment.
