AI Technical Summary

Technical Problem

Existing electric drives in air valves and dampers experience malfunctions due to misalignment or jamming of the solenoid's core and plunger, primarily caused by bracket loosening and metal fatigue, leading to poor positioning accuracy and operational inefficiencies.

Method used

The electric drive mechanism is reinforced with three additional attachment points using spot welding to secure the bracket to the gearbox plate, ensuring rigidity and preventing mobility, thereby maintaining accurate positioning and preventing jamming.

Benefits of technology

The reinforcement enhances the reliability and efficiency of the electric drive by maintaining consistent operation and preventing bracket deviation, ensuring reliable positioning of the pusher and pinion throughout the drive's service life.

Abstract

FIELD: electric drives.SUBSTANCE: invention relates to electric drives for air valves and dampers of air conditioning and ventilation systems. The electric drive of the valves / dampers includes a solenoid with a core and a pusher, fixed in the housing of the electric drive by means of a bracket made of thin stamped steel, which is attached to the gearbox plate by a screw connection at two points. The bracket wall has a groove for routing power wires. The bracket is additionally secured to the gearbox plate by spot welding, two points of which are made on the wider arm of the bracket before the groove and one point on the narrow arm of the bracket after the groove. This reinforcement eliminates the mobility of the bracket, maintains its resistance to external forces and eliminates the loss of strength of the bracket wall.EFFECT: increased efficiency of the pusher when fixing the pinion and reliable and stable operation of the electric drive as a whole for the entire period of operation.1 cl, 7 dwg
