High Quality Pitch Yaw Bearing for Wind Generator
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 High Quality Pitch Yaw Bearing for Wind Generator should bear the impact load caused by uncertain wind force.Pitch High Quality 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 Pitch High Quality Yaw Bearing for Wind Generator 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.
.LYXQL High Quality Yaw Bearing for Wind Generator can support combinations of large radial force, medium axial force and tilting moment with small or zero clearance. LYXQL Pitch Yaw Bearing can reach negative clearance and has extremely high rotation accuracy. The product outer dimension can be from 500mm to 25000mm.
LYXQL Pitch Yaw Bearing for Wind Generator------Technical Data:
1. Material: 42CrMo, 50Mn
2. Precision: P0. P6. P5.
3. Outside diameter: 500~25000mm
4. Cage/retainer: Nylon or aluminum
5. Gear type: non-geared, internal gear and external gear, gear hardened
LYXQL Yaw Bearing for Wind Generator----Surface treatment:
1: black surface treatment
2: Surface sandblasting and painting
3: Surface chrome plating
4: Surface spray zinc treatment
5: Surface phosphating treatment
6: Dacromet treatment
LYXQL High Quality Pitch Yaw Bearing for Wind Generator--- 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.
LYXQL Pitch High Quality Yaw Bearing------Packaging Details:
Step 1: Covered with the anti-rust oil
Step 2: wrapped with the plastic film;
Step 3: Packed with Kraft paper and professional belts;
Step 4: Put into wooden box to avoid the rust or the moist;
Remark: Normally, plastic film+ Kraft +belt+ wooden box, but customized packing available,
LYXQL High Quality Pitch Yaw Bearing for Wind Generator--- Maintain
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.
