绳轮维护保养要求及报废条件说明
EXPLANATION OF MAINTENANCE REQUIREMENTS AND SCRAPPING CONDITIONS FOR ROPE PULLEYS
一、绳轮维护保养要求
1、绳轮组件检查：
1.1 绳轮组件在安装前检查是否存在淋雨、生锈、磕伤、变形、裂纹等现象，绳轮转动是否灵活。
1.2 定期对绳槽油泥、轴承及轮体表面灰尘、杂质等进行清洁保养。
1.3 定期对绳轮是否存在绳槽缺损、不正常磨损、严重变形等进行检查。
1. Inspection of rope pulley components:
1.1 Before installation, inspect the rope pulley assembly for signs of rain, rust, scratches, deformation, cracks, etc.,
and ensure that the rope pulley rotates flexibly.
1.2 Regularly clean and maintain the oil sludge in the rope groove, dust and impurities on the surface of the bearing and wheel body.
1.3 Regularly inspect the rope pulley for groove defects, abnormal wear, severe deformation, etc.
2、半封闭及敞开式轴承维保保养：
2.1半封闭或敞开式轴承需定期加注润滑脂。
2.2新绳轮出厂后半年内无需加注润滑脂，后期≥1次/每半年。
2.3维护时注脂量控制在50-100g。
2.4注脂方式:将填充好润滑脂的油枪枪嘴垂直套在绳轮注油杯上，锁紧前端固定螺母，
按压握把进行加油操作50次左右(如下图)：
2.5注脂结束后，启动电梯上下运行10次左右，保证轴承内部润滑脂分布均匀，
检查并清理外溢油脂。
2. Maintenance of semi enclosed and open bearings:
2.1 Semi enclosed or open bearings need to be regularly lubricated with grease.
2.2 After the new rope pulley leaves the factory, there is no need to add lubricating grease within six months, and in the later stage,
it should be ≥ once/every six months.
2.3 Control the amount of grease injected during maintenance between 50-100g.
2.4 Greasing method: Place the grease flled nozzle of the oil gun vertically on the rope wheel oil cup, lock the front fxed nut,
and press the grip for about 50 refueling operations (as shown in the following figure).
2.5 After the grease injection is completed, start the elevator to run up and down for about 10 times
to ensure uniform distribution of lubricating grease inside the bearings. Check and clean any spilled grease.
二、绳轮报废条件
参照GB/T 31821-2015电梯主要部件报废技术条件4.4.6：
滑轮出现下列情况之一，视为达到报废技术条件：
1、绳槽严重磨损。
2、绳槽缺损或不正常磨损。
3、轮毂与轴承、轴与轴承出现明显滑移、间隙或位移。
4、出现裂纹。
5、出现严重变形或老化龟裂。
Refer to GB/T 31821-2015 Technical Conditions for Scrapping of Main Components of Elevators 4.4.6:
The pulley shall be deemed to meet the technical conditions for scrapping if one of the following conditions occurs:
1. The rope groove is severely worn.
2. The rope groove is damaged or abnormally worn.
3. There is significant slip, clearance, or displacement between the wheel hub and bearings, as well as between the shaft and bearings.
4. Cracks appear.
5. Severe deformation or aging cracking occurs.
