The design and assembly of crossed roller bearings are key links to ensure their performance, life and stable operation of the entire mechanical system, and are also key links to ensure their normal operation and service life.

Design and Assembly of Crossed Roller Bearings

1. Design of Crossed Roller Bearings

Structural Design

The structural design of crossed roller bearings is the basis of their performance. The bearing’s load capacity, running accuracy, friction and wear, and lubrication and sealing factors must be fully considered during design.

The cross arrangement of rollers, raceway shape, cage structure, etc. all need to be carefully calculated and optimized to ensure that the bearings can perform well under various working conditions.

Common types of crossed roller bearings include RB type (inner ring as a whole, outer ring split), RE type (inner ring split, outer ring as a whole), RU type (inner and outer ring as a whole, with mounting holes), RA type (inner ring as a whole, outer ring split, ultra-thin), etc. Each type has its specific application scenarios and advantages.

Material Selection

Material is one of the key factors that determine bearing performance. When selecting materials, it is necessary to consider its strength, hardness, wear resistance, corrosion resistance, and thermal stability.

Common materials include high carbon chromium bearing steel, stainless steel, ceramics, etc. Different materials have different performance characteristics and need to be selected according to the specific use environment and requirements of the bearing.

Crossed roller bearings are a type of high-precision bearing with a unique structure that allows them to support radial, axial, and moment loads simultaneously. Their structure and design offer high rigidity and compact size, making them suitable for applications requiring high accuracy and stiffness, such as robotics, machine tools, and medical equipment.

Structure of Crossed Roller Bearings

Inner and Outer Rings:

Inner Ring: Often split into two pieces to facilitate the insertion of the rollers and retainers.

Outer Ring: Can be one piece or split, depending on the design. The outer ring typically has a groove to house the rollers and retainers.

Rollers:

Cylindrical rollers are positioned between the inner and outer rings.

Rollers are arranged at right angles (90 degrees) to each other in an alternating pattern, which allows the bearing to handle loads from multiple directions.

Separator/Retainer:

A retainer or separator is used to keep the rollers in their correct positions and to prevent them from contacting each other.

The retainer can be made of materials like metal or plastic, ensuring smooth rotation and reduced friction.

Raceways:

Both the inner and outer rings have precisely machined raceways that match the rollers’ profiles.

The raceways ensure the rollers are guided accurately, distributing the loads evenly across the rollers.

Features and Benefits

High Load Capacity:

The crossed arrangement of rollers allows the bearing to support loads in all directions (radial, axial, and moment) with high capacity.

High Rigidity and Precision:

The compact design and precise manufacturing of the raceways and rollers provide high rigidity and accuracy, which is crucial for precision applications.

The intelligent compact shelving control system is an advanced system that integrates technologies such as sensors, actuators, computers, and network communications. It aims to realize the automated control and management of storage, retrieval, and movement of goods in the compact shelving warehouse. It is mainly composed of two parts: hardware and software. The specific control system types and characteristics are as follows:

1. Hardware Part

Sensor: used to monitor the status of the storage area in real time, such as detecting parameters such as shelf position, temperature, humidity, and lighting. These sensors are the basis for the system to achieve precise control and optimization.

Actuator: Perform specific actions according to the instructions of the control system, such as driving the lifting, movement, and rotation of the compact shelving.

Controller: As the core component of the system, it is responsible for receiving sensor signals, processing user instructions, and controlling the actuator to perform corresponding operations.

2. Software Part

Control system software: provides a user operation interface to realize human-computer interaction, while processing data from sensors and user instructions to control the movement and status of the compact shelving.

Database management system: used to store and manage cargo information, location data, operation records, etc. in the warehouse, and provide data support for the intelligent management of the system.

User interface: includes various forms of operation interfaces such as touch screens, remote controls, and computers, through which users can easily control and manage the compact shelving.

3. Common control system types

Touch screen control system

Users can operate and manage through the touch screen interface, such as lifting, moving, rotating the rack, selecting storage cells and index retrieval, etc.

Remote control system

Users can control and operate the compact rack through the remote control. The remote control usually has various buttons and functions. Users can select storage cells, control the movement and rotation of the rack through the remote control, etc.

Industrial racking come in a wide range of specifications and dimensions to meet the varying needs of different industries. The specific requirements often depend on the types of items being stored, the weight of these items, and the available space. Here are some general specifications and dimensions typically found in industrial racking.

Industrial Racking Common Dimensions

Height

Standard heights typically range from 6 feet (72 inches or 183 cm) to 24 feet (288 inches or 732 cm).

Shelves are often adjustable, allowing the height between shelves to be customized.

Width

Common widths range from 3 feet (36 inches or 91 cm) to 12 feet (144 inches or 366 cm).

Widths can be customized to fit specific storage needs.

Depth

Standard depths range from 12 inches (30 cm) to 48 inches (122 cm).

Deeper shelves are available for storing larger or bulkier items.

Load Capacity

Light Duty: Typically supports up to 250 lbs (113 kg) per shelf.

Medium Duty: Typically supports 250 lbs to 800 lbs (113 kg to 363 kg) per shelf.

Heavy Duty: Typically supports 800 lbs to 3000 lbs (363 kg to 1360 kg) or more per shelf.

Materials

Steel:

Most industrial shelves are made from heavy-duty steel for maximum durability and strength.

Often powder-coated or galvanized to resist rust and corrosion.

Servo bearings are bearings designed specifically for servo motors. They have the characteristics of high precision, high rigidity and high speed to meet the needs of servo motors in precise control, high-speed operation and frequent start and stop. The following is a detailed introduction to servo bearings:

Servo Bearings Types and Characteristics

Servo bearings mainly include deep groove ball bearings, angular contact ball bearings, ceramic ball bearings and other types. Each type has its own unique characteristics and applicable scenarios:

Deep groove ball bearings: This is one of the most common types of bearings, with simple structure, easy maintenance, and strong load-bearing capacity. In servo motors, deep groove ball bearings are often used to bear radial loads and certain axial loads.

Angular contact ball bearings: This type of bearing can bear radial loads and axial loads at the same time, and has high speed and precision. In servo motors that require high precision and high speed, angular contact ball bearings are an ideal choice.

Ceramic ball bearings: Ceramic materials have the characteristics of low density, high hardness, high wear resistance and good thermal stability, so ceramic ball bearings have lower friction coefficients, higher speeds and longer service life. In high-end servo motors, ceramic ball bearings are increasingly widely used.

Servo Bearings Application Fields

Servo bearings are widely used in various occasions that require precise control and high-speed operation, such as:

Industrial automation: In CNC machine tools, robots, automated production lines and other equipment, servo motors are one of the core components, and servo bearings are the key to ensuring the normal operation of servo motors.
