Page 10: Construction Group Description
4.0 Structure and function CAHB-10 series This actuator is to be used exclusively for installation into a dy- namic centric-compression or tensile-loaded lift. The linear actuator consists of a motor part (3) and a linear unit (5), connected with each other by a bayonet joint. The actuator consists of a direct current motor with spur gear which sets in motion a trapezoidal sliding spindle system with shaft joint. Via the lead screw mount, the sliding spindle trans- forms the rotation of the gear into a linear motion of the actuator (1). The front hinge head (4) and the rear hinge head (7) transmit the actuator power to both sides of the application. 4.3 Construction group description Motor The motor is a 12 or 24 V DC. The motor’s shaft powers a spur gear. The lift speed depends on the load. The motor unit is sur- rounded by metal housing. The metal housing cannot be opened. Gear unit The spur gear is directly powered by the motor shaft which moves a trapezoidal sliding spindle. Linear unit The actuator extends and retracts the push tube. The linear unit is surrounded and protected by the guiding tube. The push tube of the actuator is connected to the spindle with a lead screw nut. The linear unit is connected to the motor with several screws. These screws should not be loosened or removed. 4.4 Connections Figure 4 1. -
