Rokee® Customized Clutch Type Drum Gear Coupling for Customers, Rokee® is a well-known high-quality supplier of couplings and technical services in China.
The clutch type drum tooth coupling is an important functional extension of traditional drum tooth couplings. It cleverly combines the transmission advantages of drum teeth with the operational convenience of clutch devices, creating a mechanical connection device that combines transmission reliability and operational flexibility. This type of coupling belongs to the category of rigid flexible couplings, which not only has the torque transmission capability of rigid couplings, but also has a certain axis deviation compensation function. At the same time, it achieves manual or automatic control of the connection and separation of the master and slave shafts through a specially designed clutch mechanism.
From the perspective of structural composition, the clutch type drum gear coupling is mainly composed of several core components: the internal gear ring is usually installed on the drive shaft as a fixed part, and its internal teeth adopt a standard involute tooth profile; The outer gear shaft sleeve is equipped with drum shaped outer teeth, whose tooth tips are machined into spherical shapes to form a meshing relationship with the inner gear ring; The clutch device is the key to the entire system, which controls the axial displacement of the outer gear shaft sleeve through mechanical, hydraulic, or pneumatic means to achieve meshing or disengagement with the inner gear ring; The sealing system ensures the retention of lubricants and the elimination of pollutants, which is crucial for maintaining good working condition of the tooth surface; In addition, auxiliary components such as end caps and connectors are used to integrate and fix the overall structure.
Compared with traditional drum gear couplings, the clutch type design increases the axial freedom of movement, allowing the outer gear shaft sleeve to slide along the axis direction under the action of the clutch device, thereby quickly changing the meshing state. This structural innovation enables the connection and interruption of the transmission system of the equipment without the need for complete shutdown, greatly improving operational efficiency and system flexibility.
In terms of working principle, when the clutch device is in the "engaged" state, the drum shaped teeth of the outer gear shaft sleeve fully mesh with the inner gear ring, and power is transmitted from the drive shaft to the driven shaft through tooth contact; When it is necessary to interrupt power transmission, the clutch device acts to move the outer gear shaft sleeve axially out of the meshing position. At this time, although the drive shaft is still rotating, the driven shaft remains stationary or is driven by other power sources. This working characteristic makes it particularly suitable for complex working conditions that require frequent starting, stopping, reversing, or synchronous/asynchronous switching.
