Luoyang Hongyuan Bearing Technology Co., Ltd. was established in December 2005. It mainly focuses on the production of precision bearings. It specializes in the development and manufacture of three series of products: precision turntable bearings, crossed roller bearings, and special bearings for robot reducers. Continuous improvement and breakthroughs in technology research and development and processing technology have improved the comprehensive performance of bearings and broken the long-term monopoly of similar foreign products in China. At present, it has occupied 80% of the domestic market for YRT rotary table bearings and precision crossed roller bearings, and 90% of the market. The domestic harmonic reducer bearing market, 30% of the domestic Rv reducer bearing market; 50% of the products are exported to Europe, North America, India, South Korea, Taiwan and other countries and regions. Welcome new and old customers to visit and guide!
CRBH type (integrated inner and outer ring, ultra-thin), this model is ultra-thin RU, due to the ultra-thin design and the outer ring and inner ring have no mounting holes, flanges and support seats are required for installation. In addition, since the outer ring and inner ring are integral structures, installation has no effect on performance, so stable rotation accuracy and torque can be obtained. It is suitable for occasions where the outer ring and inner ring rotate but require miniaturization.
RU type (integrated inner and outer rings, with mounting holes), since the outer ring and inner ring have mounting holes, there is no need to fix the flange and support seat during installation. In addition, since the outer ring and the inner ring are of integral structure, the installation has almost no influence on the performance, so stable rotation accuracy and torque can be obtained, and it is suitable for the occasion where the outer ring and the inner ring rotate.
Type RAU (integral inner ring, separate outer ring, ultra-thin) This type is a compact type that reduces the thickness of the inner and outer rings of Type RB to the limit. The structure is the same as that of Type RB. Parts with compact design, such as the rotating part of the robot arm.
In crossed roller bearings, since the cylindrical rollers are vertically arranged on the 90° V-shaped groove rolling surface through spacers, crossed roller bearings can bear radial loads, axial loads and moment loads, etc. multi-directional loads. The size of the inner and outer rings is miniaturized, and the extremely thin form is close to the limit of small size, and has high rigidity, so it is more suitable for the joints and rotating parts of industrial robots, the rotating table of machining centers, the rotating part of manipulators, Precision rotary tables, medical equipment, measuring instruments, IC manufacturing equipment and other equipment.
Rotational accuracy: spacers are installed between the vertically arranged rollers in the bearing, which prevents the inclination of the rollers and the mutual friction between the rollers, and reduces the rotational moment. In addition, compared with conventional steel cages, there is no edge stress concentration or locking of the rollers. At the same time, because the inner ring or outer ring is divided into two structures, the bearing clearance can be adjusted, and even if a preload is applied, it can rotate smoothly with high precision.
