gear drive

Gear transmission is a mechanical transmission that uses the teeth of two gears to mesh with each other to transmit power and motion. According to the relative position of the gear axis, it can be divided into parallel shaft cylindrical gear transmission, intersecting shaft bevel gear transmission and staggered shaft helical gear transmission. With compact structure, high efficiency, long life and so on.

Operating characteristics of gear transmissions
1. Large transmission ratio and wide speed range: good lubricity of lubricating oil is required 齿轮传动装置运行及润滑特点—长沙合轩化工齿轮润滑解决方案
2. Large transmission power and high contact stress on the tooth surface: strong bearing capacity of lubricant is required
3. Relative radius of curvature is small: good torque resistance
4. Discontinuous changes in contact state and load: Lubrication film is required to have good expandability and recovery
5. Tooth surface machining accuracy and smoothness are generally not high, and the lubrication state is boundary and mixed lubrication state: the oil film formed is required to have sufficient thickness and strength
的润滑油 6. The gear meshing motion is a mixed friction method of sliding and rolling. The tooth surface is in line and point contact. The actual contact surface is very small and the local load is extremely large: high -pressure oil

Technical requirements for gear lubricants

1. Suitable viscosity: Comprehensive anti-scratch, noise reduction and other high viscosity requirements and energy saving, cooling and other low viscosity requirements to achieve a suitable viscosity grade.

2. Good viscosity and temperature: It can keep the gear oil relatively stable viscosity in high and low temperature environment, and achieve good lubrication in a wide temperature range.
3. Good low-temperature fluidity: The low-temperature viscosity of oil products increases, the fluidity becomes poor, it is not easy to enter the occlusal surface, and it is easy to form friction and increase wear.

的使用寿命。 4. Good oxidation stability: Extend the service life of gear oil .

:由于油品泡沫的存在,致使油品在齿轮表面不能形成连续的润滑膜,从而造成齿面蚀刻或疲坑,同时也会加剧油品的氧化。 5. Good foam resistance : Due to the presence of oil foam, the oil cannot form a continuous lubricating film on the surface of the gear, which causes the tooth surface to etch or fatigue, and it will also increase the oxidation of the oil.
6. Good anti-emulsification: Emulsification of oil products will cause the oil film strength to decrease or rupture, which will cause gear abrasion. 齿轮传动对齿轮润滑油脂的技术要求—长沙合轩化工齿轮润滑解决方案
7. Good rust and corrosion resistance: rust and corrosion will cause pits on the tooth surface, reducing the service life of the gear.
性:可减少齿轮磨损,延缓齿面疲劳,避免出现蚀刻、疲坑、破裂等现象发生。 8. Good anti-wear extreme pressure : can reduce gear wear, delay tooth surface fatigue, and avoid the occurrence of etching, fatigue, cracks and other phenomena.
9. Good friction reduction: It can effectively reduce friction, save energy, reduce noise and slow down vibration.

品长期保持稳定的粘度,延长油品的使用寿命。 10. Good anti-shear stability: make gear oil products maintain stable viscosity for a long time and prolong the service life of oil products.

11. Good sealing material adaptability: there must be no damage to the seals, otherwise it will cause poor sealing and leaks or impurities.

齿轮齿面的损伤—长沙合轩化工齿轮润滑解决方案

Gears are designed in various ways to transmit motion in different industrial fields. There are various factors in the work that cause the gear to stop suddenly. 左右都是因为齿面损坏引起的。 According to statistics, about 70% of defects in gear transmissions are caused by tooth surface damage .

The right lubricant eliminates many sources of tooth surface damage

Use light oil or high adhesion lubricant? The question is irrelevant. 轻载齿轮还是低速重载齿轮,或是闭式齿轮箱和开式齿轮传动装置都并无关系。 It does not matter whether it is a fast light load gear or a low speed heavy load gear, or a closed gearbox and an open gear transmission. But when the gears are meshed together, the right lubricant is one of the most important factors for trouble-free operation of the equipment. For example, scratches and wear depend heavily on the lubricant. Poor lubricants directly cause pitting, abrasion and scratches. Consequences of insufficient lubricant often include increased wear or deformation.
