GIICL type medium hard tooth surface drum gear coupling

Product Details

The periodic working shaft of the tooth surface of the inner and outer teeth of the GIICL drum tooth coupling is the same as the general gear coupling in the transmission principle, the difference is that there is a floating shaft in the middle and a thrust button and thrust plate mechanism to ensure that the coupling plays a positioning role when running in the vertical direction. In addition, the design also considers the floating of the intermediate shaft and the necessary clearance of each part when disassembling and installing the coupling. The radius of curvature of the drum curve is proportional to the amount of thinning on one side of the inner teeth, so the radius of the drum circle should be as large as possible. The radius of curvature of the drum curve is proportional to the amount of thinning on one side of the inner teeth, which causes the teething phenomenon of the inner and outer teeth to occur, which affects the service life of the coupling.

When the gear coupling of the GIICL drum tooth coupling is lubricated with grease, if the coupling space is not filled with grease, the bitten tooth surface will lack adjustment and cause dryness This grave mistake must be corrected. Caused by insufficient lubrication during maintenance. Because the teeth of the gear coupling are fixed and meshed, we usually think that they are not lubricated. When the tooth coupling is working, the tooth surface of the inner and outer teeth periodically works in the axial relative direction, which will inevitably form tooth surface wear and power consumption, therefore, the tooth coupling needs to work in a good and sealed state.

The drum tooth surface of the non-conjugate tooth surface is gradually distorted with different end cross-sections, and the dotted line formed by the displacement amount and the axial coordinates is called the drum curve, which is an important geometric parameter of the drum tooth coupling. The drum curve is mostly an arc, first of all, you can observe with the naked eye whether the coupling has damage to the parts, if there is no visible damage to the naked eye, the wind turbine monitoring system has not repeatedly reported the failure of the gearbox output shaft torque speed and the generator rotor torque speed mismatch, which can be preliminarily judged to be normal slippage.

The error of the levelness and coaxially of the two axes is too large, which exceeds the normal range that the coupling can compensate for, so the inaccurate meshing of the shaft teeth and the internal teeth causes local contact, and the additional torque is overflowed. Due to the particularity of the drum load situation, the connection between the drum and the output shaft of the reducer has three requirements: radial load and torque deflection angle. The connection types often used include reducer tooth shaft extension and drum inner ring gear connection, reducer hollow shaft and drum short shaft connection, drum tooth coupling connection, etc.
