Product Description Slewing Bearing1.Slewing bearing introduction Slewing bearing is also called slewing ring, turntable bearing, and rotary table bearing. Slewing bearing is a bearing that able to bear axial load, radial load and overturning torque. Under normal circumstances, slewing bearing has their own mounting holes, lubricant holes and seal holes, to meet the different needs of the various host working under the various conditions.On the other hand, slewing bearing has characteristics of compact structure, guide rotating convenient, easy to install and maintaining easily.013.30.500/014.30.500 is ball slewing ring bearing with internal gear ,made in Luoyang China013.30.500/014.30.500 Product structure Harmonic Drive, a new technology, has attracted extensive attention from all countries since its emergence. The company introduced this technology and developed the first harmonic drive reducer, becoming the first global leader in overall motion control. Harmonic reducer has been developed abroad for more than ten years, because it has many advantages that can't be replaced by ordinary transmission methods, and has a wide range of application space. The research on harmonic reducer started earlier in China, but compared with foreign countries, there is still a big gap. At present, China is mainly in the imitation stage, and the domestic market has been monopolized by foreign similar products. The harmonic reducer was developed in China in 1960s and 1970s, and many manufacturers specialized in production and formed series.Small size and light weight Compared with the previous gear device, it has a volume of 1/3 and a weight of 1/2, but it can obtain the same torque capacity and reduction ratio, and realize miniaturization and light weight. 6. High torque capacity The flexspline is made of special steel with high fatigue strength. Different from the common transmission device, the number of teeth engaged at the same time accounts for about 30% of the total number of teeth, and it is in surface contact, so that the pressure borne by each gear is reduced and a high torque capacity can be obtained. 7. High efficiency The sliding of the meshing part of the gear teeth is very small, which reduces the power loss caused by friction. Therefore, while obtaining a high reduction ratio, it can maintain high efficiency and realize the miniaturization of the driving motor. 8. Low noise The meshing speed of gear teethis low, and the transmitted motion force is balanced, so the operation is quiet and the vibration is extremely small.

Usually, the teeth with the same modulus are cut out on the rigid wheel and the flexible wheel, but the number of teeth is different (that is, the number of teeth of the flexible wheel is two less than that of the rigid wheel). The tooth number difference of harmonic drive represents the deformation wave number of flexspline. The most common one is harmonic drive with wave number w-2. In the free state (without generator), the two wheels are in concentric position, and the tooth clearance between the rigid wheel and the flexible wheel is uniform. The generator installed in the flexspline radially deforms the flexspline into an oval shape. At this time, on the long axis of the ellipse, the teeth mesh along the whole working height, while on the short axis, a radial gap is formed between the tips of the teeth. During the rotation of the generator, the shape of the flexspline is always close to the above shape. Compared with other drives with the same speed ratio, harmonic drive has high efficiency because of the small number of moving parts and the low speed of meshing tooth surface Advantages of harmonic reducer:1. High reduction ratioHigh reduction ratio of 1/30 ~ 1/320 can be obtained by single stage coaxial. The structure is simple, but the device with high reduction ratio can be realized.2. Small backlashHarmonic Drive is different from meshing with ordinary gears, and its tooth gap is extremely small, which is an indispensable element in the field of controllers.3. High precisionMulti-teeth mesh at the same time, and two 180-degree symmetrical gears mesh, so the influence of gear pitch error and cumulative pitch error on rotation accuracy is relatively average, which makes the position accuracy and rotation accuracy reach a very high level.4. Less parts and easy installationThree basic components achieve high reduction ratio, and they are all coaxial, so the kit is easy to install and simple in shape.
