How to make the measurement in charging the liquid of limitted torque hydraulic cam and groove coupling?

　　Generally use dosage cup to do measurement. Use the dosage cup or bottle to measure filling volume of cam and groove coupling.

　　To observe the oiling hole. Some cam and groove coupling, especially vertical coupling, must notice, oiling mouth position is 80% liquid filling position, can be the first oil charge to 80%, and then filling the right determined by experiment. At last see whether it is right.

　　Observe the liquid filling angle. Many imported cam and groove coupling is in the housing groove, liquid filling rate corresponding to the transmitted power. For example, the British STC475 cam and groove coupling, when the transmission power is 90kw, the liquid filling angle of 50 ˚ (angle oil hole and a vertical line). In the domestic hydraulic cam and groove coupling, shell basically no, because the cam and groove coupling structure is different, so the washing liquid angle also each are not identical, liquid filling can be specified according to the product specification on the corner filling. If we can't find the manual or instructions do not form liquid filling angle, can probably estimate, liquid filling rate of 80% corresponding to the general liquid filling angle is about 45%, you can press the than angle liquid filling, filling liquid quantity and the experimentally determined.
