[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] This utility model discloses an adjustable speed electric gear motor, comprising a front cover 2, a transition cover 3, a housing 7, and a rear cover 8 connected in sequence. The front cover 2 is connected to a front support drive shaft 1. The rear cover 8 has a solenoid valve hole and a throttle valve hole, with the solenoid valve hole corresponding to a solenoid valve 9 and the throttle valve hole corresponding to a throttle valve 10. A bearing 4 is housed inside the front cover 2. A coupling sleeve 5 is housed inside the transition cover 3. The housing 7 houses a drive shaft and a drive gear 6 of a drive gear pair. The tail of the drive gear 6 of the drive shaft and drive gear pair uses spline drive. The front cover 2, transition cover 3, housing 7, and rear cover 8 are connected by seals and fasteners. The front cover 2 drives an external fan via the front support drive shaft 1.

[0021] This invention adds a bearing front support structure to the existing ordinary motor to meet the radial force requirements of the external fan connected to the motor. The drive shaft and the driving gear 6 of the transmission gear pair in this invention both employ spline transmission at their tails, capable of handling the torque requirements of large-displacement motors and special operating conditions. The rear cover 8 of this invention adds two valve holes to the original rear cover: a solenoid valve hole and a throttle valve hole. These two valves are crucial for realizing the motor mechanism.

[0022] This invention is used to drive a fan, which needs to withstand a certain radial force. Furthermore, the motor's start and stop can be controlled by a solenoid valve according to customer requirements, and the motor speed can be manually adjusted by an external throttle valve while the motor is operating. To address these three requirements, the invention improves upon the original motor structure: a front support structure is added to the motor output section, so that the radial force generated by the external fan is borne by the bearing; valve holes are added to the rear cover of the motor for mounting a solenoid valve and a one-way throttle valve, respectively. The solenoid valve's control voltage and operating mechanism are selected according to customer needs, and the throttle valve's appropriate flow control range is selected based on the motor's flow requirements.

[0023] This utility model has a novel design and features the advantages of being able to withstand radial force, control the start and stop of the electric motor, and control the motor speed manually, which greatly expands the application range of the motor.
