JMⅡJ Type Intermediate Shaft Type Diaphragm Coupling

JMⅡJ type with intermediate shaft typeDiaphragm couplingCompared with the gear coupling, there is no relative sliding, no lubrication, sealing, no noise, basically no maintenance, more convenient to manufacture, and can partially replace the gear coupling.

JMⅡJ intermediate shaft type diaphragm coupling is widely used in shaft transmission of various mechanical devices, such as water pumps (especially high-power, chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textiles High-speed power transmission systems of machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopters), and naval vessels are commonly used in high-speed transmission shaft systems after being dynamically balanced.

JMⅡJ型接中间轴型膜片联轴器是我国推广应用的高性能挠性联轴器，且工业发达   已普遍采用。在实际应用中一般采用接中间轴型，以提高两轴线偏移补偿性能。

JMⅡJ型接中间轴型膜片联轴器是由几组膜片（不锈钢薄扳）用螺栓交错地与两半联轴器联接，每组膜片由数片叠集而成，膜片分为连杆式和不同形状的整片式。

JMⅡJ型接中间轴型膜片联轴器安装使用说明 

1. Before installation, check whether the prime mover and working machine shafts are concentric, whether there are wrapping paper and scratches on the surfaces of the two shafts, whether there are sundries in the inner holes of the two half couplings of the coupling, and whether there is any edge of the inner hole. If there are bruises, the shaft and half coupling should be cleaned up, and the bruises should be treated with a fine file.Then check whether the inner hole diameter and length of the two half couplings are consistent with the diameter and shaft elongation of the prime mover and working machine.In general selection, it is better to let the length of the prime mover and the working machine end half coupling be less than the shaft extension of 10-30mm. 

2. 为了便于安装，是将两个半联轴节放在120--150的保温箱或油槽中进行预热，使内孔尺寸涨大很容易装上。安装后保证轴头不能凸出半联轴节端面，以 齐平为好。 检测两半联轴节之间的距离：沿半联轴节的法兰盘两内侧测出3--4点的读数取平均值，及加长段与两个膜片组实测尺寸之和，两者误差控制在0—0.4mm范 围之内。 

3. 找正：用百分表检测两半联轴节法兰盘端面和外圆跳动，当法兰盘外圆小于250mm时跳动值应不大于0.05mm；当法兰盘外圆大于250mm时，跳动值应不大于0.08。
