AI Technical Summary

Problems solved by technology

These devices often have their rated speeds, and if they run over the speed, it will cause damage. For example, the overspeed of the conveyor will cause excessive conveying volume and blockage. For example, the overspeed operation of the elevator will cause safety accidents, and the speed of the motor will be affected by frequency and Voltage and other factors change, when the frequency converter is damaged, it will cause a speeding accident, therefore, a device to prevent the overspeed operation of rotating equipment is needed
[0003] In the existing technology, some use sensors to detect the speed. When the speed is too high, the controller controls the motor to run at a reduced speed. The stability of this technology is not high enough, and in the harsh environment of high temperature and high pressure, the sensor, circuit Components such as controllers are easily damaged and malfunctioned

Embodiment approach 1

[0089] Such as Figure 1-12 As shown, this embodiment provides an anti-overspeed motor, including:

[0090] The motor body 200 includes a casing 201, a stator 209, a rotor 205 and a motor shaft 206;

[0091] The overspeed prevention mechanism 100 is arranged at the tail of the motor body 200 and connected with the motor shaft 206 for preventing overspeed operation;

[0092] The breaking mechanism 300 is arranged between the overspeed preventing mechanism 100 and the motor body 200, and is used to disconnect or connect the overspeed preventing mechanism 100 and the motor body 200;

[0093] The speed regulating operation mechanism 400 is connected with the anti-overspeed mechanism 100 and is used for adjusting the running resistance of the overspeed prevention mechanism 100 .

[0094] Wherein, the motor body 200 is an ordinary motor, and when electrified, the motor shaft 206 is driven to rotate, thereby providing mechanical energy. The anti-overspeed mechanism 100 is used to ...

Embodiment approach 2

[0167] refer to Figure 13-Figure 17 The main difference between this embodiment and Embodiment 1 is that the anti-overspeed mechanism 100 uses a constant speed mechanism 130 and an adjustment mechanism 140 of different structures, while the motor body 200, the breaking mechanism 300, and the housing 110 of the overspeed prevention mechanism 100, non- The setting of the Newtonian fluid, the connection of the rotating shaft 120 and the stirring working principle and beneficial effect of the first stirring blade 135 are all the same as those of Embodiment 1, and the differences will be described in detail below.

[0168] The constant speed mechanism 130 of this embodiment adopts two radially evenly distributed first stirring blades 135, which also includes:

[0169] The sliding sleeve 131 is sleeved on the rotating shaft 120, and the sliding sleeve is provided with a chute 136;

[0170] The slider 132 is embedded in the chute 136 and can move radially relative to the chute 136,...

Abstract

The invention discloses an anti-overspeed motor, which comprises an anti-overspeed mechanism, a motor body, a breaking mechanism and a speed regulation operating mechanism. The anti-overspeed mechanism is arranged at the tail part of the motor body, is connected with a motor shaft and is used for preventing overspeed operation. The breaking mechanism is arranged between the anti-overspeed mechanism and the motor body and is used for disconnecting or connecting the anti-overspeed mechanism and the motor body. The speed regulation operating mechanism is connected with the overspeed prevention mechanism and used for regulating the running resistance of the overspeed prevention mechanism. According to the invention, the motor can be ensured not to rotate at an overspeed, unnecessary loss caused by the overspeed is avoided, a user can decide whether to operate at a limited speed or not through the breaking mechanism, and the motor can operate safely and stably even in a severe environment with high temperature and high pressure, and can be widely applied to various occasions needing speed limitation.

Description

technical field [0001] The invention relates to a rotating device, in particular to an anti-overspeed motor. Background technique [0002] Motor (Motor) is a device that converts electrical energy into mechanical energy. As a power device, it is widely used in other devices. Other devices must rely on motors or other power to drive them to move or rotate. For example, elevators rely on motors To drive it up and down, the car relies on power to drive its rotation, and the fan relies on a motor to drive its rotation. These devices often have their rated speeds, and if they run over the speed, it will cause damage. For example, the overspeed of the conveyor will cause excessive conveying volume and blockage. For example, the overspeed operation of the elevator will cause safety accidents, and the speed of the motor will be affected by frequency and Voltage and other factors change, and when the inverter is damaged, it will cause a speeding accident. Therefore, a device to prev...
