ISO Certified Pitch Yaw Bearing with ring gear
Luoyang Xinqianglian Slewing Bearing Co., Ltd. ( Hereinafter referred to as the LYXQL) founded in 2003, is located in the ancient capital of nine dynasties Luoyang in Henan province. LYXQL is a national key high-tech enterprises and become a GEM listing company successfully on July 13,2020 (stock code "300850").
LYXQL Pitch ISO Certified Yaw Bearing should bear the impact load caused by uncertain wind force. Pitch Yaw Bearing have the characteristics of intermittent work, frequent start and stop, large transmission torque and high transmission ratio. Therefore, the yaw bearing requires small clearance; Compared with yaw bearing, pitch bearing bears larger impact load and larger vibration transmitted by blade, so it is required to have zero clearance or small negative clearance to reduce fretting wear of rolling working surface.
The characteristics of incomplete rotation of LYXQL ISO Certified Pitch Yaw Bearing with ring gear make the inner and outer rings of the bearing swing within a small angle range. Therefore, the rolling body does not roll along the whole raceway, but swings, that is, it only moves a small distance, and the rolling body of the same part is always under the action of load.
When the wind speed is too high or too low, the pitch system changes the attack angle of the air flow to the blade by adjusting the blade pitch, so as to change the aerodynamic torque obtained by the wind turbine and keep the power output stable. The yaw system has two main functions: one is to make the wind wheel track the wind direction; Second, due to yaw, when the cable leading out of the cabin is wound, it will be released automatically.
LYXQL Pitch ISO Certified Yaw Bearing with ring gear------Technical Data:
1. Material: 42CrMo, 50Mn
2. Precision: P0. P6. P5.
3. Outside diameter: 500~25000mm
4. Cage/retainer: Nylon or aluminum

LYXQL Pitch Yaw Bearing with ring gear--- Seal
The sealing of the cross roller slewing bearing without teeth is mainly to prevent the filled grease from leaking out, and also to prevent external dust, impurities and moisture from entering the inside of the bearing and affecting the normal operation of the bearing.
Since most of the slewing bearings work under heavy loads and low speeds, the sealing form of the bearings adopts two structures: rubber seal ring seal and labyrinth seal. The rubber sealing ring itself has a simple structure, small space occupation and reliable sealing performance. The disadvantage is that it is prone to early aging under high temperature conditions and loss of airtightness. Therefore, under high temperature conditions, the slewing bearing should adopt a labyrinth seal. In addition, the material of the sealing ring under high temperature is high temperature resistant fluoro rubber.

1. The slewing bearing should be greased regularly. According to different types of slewing bearings, the specific grease filling time is as follows: the ball type is filled with grease every 100 hours of operation; the roller type is filled with grease every 50 hours of operation .
2. The sundries on the surface of the slewing ring should be removed frequently during use, and the sealing strip of the slewing ring should be checked for aging, cracking, damage or separation. If one of these conditions occurs, the sealing strip should be replaced in time to prevent debris from entering the raceway and the loss of grease.
3. Pay close attention to the operation of the slewing ring during use. If you find that the noise, impact, or power suddenly increases, you should stop the machine immediately for inspection until all the faults are eliminated, and disassemble and inspect if necessary.
