Embodiment 1

[0027] The preload enhanced centrifugal soft starter consists of a driving end structure and a driven end structure.

[0028] like figure 1 and figure 2 As shown, the active end structure includes a bearing end cover 1 , a steel ball 2 , a rotor assembly 3 , a motor end cover 4 , a housing 5 , a magnetic steel 6 and a pin end cover 8 . The driven end structure includes a driven flange 11 connected with the pin end cover 8 .

[0029] The specific settings are as follows:

[0030] The rotor assembly 3 is arranged in the casing 5, and the two ends of the rotor assembly 3 are respectively sleeved with the pin end cover 8 and the motor end cover 4, and the inner sides of the pin end cover 8 and the motor end cover 4 are both sleeved on the On the rotor assembly 3 , the outer side of the pin end cover 8 is fixedly connected to one end of the housing 5 , and the outer side of the motor end cover 4 is fixedly connected to the other end of the housing 5 .

[0031] Both the pin end...

Embodiment 2

[0035] The difference between this embodiment and Embodiment 1 is that the nylon pin 10 in the driven end structure is added in this embodiment, and the specific settings are as follows:

[0036] The driven end structure includes a driven flange 11 and a pin ring 9 , and a nylon pin 10 arranged between the driven flange 11 and the pin ring 9 . The specific settings are as follows:

[0037] The pin ring 9 is fixed on the pin end cover 8, the end of one end of the driven flange 11 is located in the pin ring 9, and the inner ring of the pin ring 9 corresponds to the outer ring of the driven flange 11 Each position is provided with a pin hole, the pin hole on the pin ring 9 and the pin hole on the driven flange 11 form a cylindrical hole, and the nylon pin 10 is arranged in the cylindrical hole.

[0038] The nylon pin 10 has a drum-shaped structure, and the driven flange 11 is provided with a pin retaining ring 12 to prevent the pin ring 9 from coming out, such as figure 1 and ...

Abstract

The invention discloses a prepressing enhancement type centrifugal soft starter and solves the problems of huge size, high weight, big rotational inertia, incapability of applying to low rotational speed occasions of the friction type energy saving soft starter in the prior art. The prepressing enhancement type centrifugal soft starter provided by the invention comprises a driving end structure and a driven end structure, the driving end structure comprises a bearing end cover (1), a steel ball (2), a rotor assembly (3), a motor end cover (4), a casing (5) and a pin end cover (8); the driven end structure comprises a driven flange (11) connected with the pin end cover (8); the prepressing enhancement type centrifugal soft starter is characterized in that magnetic steel (6) fixed on the casing (5) through a fixing device is arranged on the casing (5). The prepressing enhancement type centrifugal soft starter provided by the invention is smaller in size and rotational inertia, can reduce additional bending moment damage of a transmission system greatly, avoids limitation from mounting position, and is stable in running.

Description

technical field [0001] The invention relates to a soft starter, in particular to a preload enhanced centrifugal soft starter. Background technique [0002] In order to solve the starting problem of the electric motor, the research on the starting technology has been started since the birth of the electric motor. If the electrical system does not use a soft-start device, it will be difficult to start the high-power motor, or the system voltage will collapse due to the start-up, and the system will not work normally. The emergence and development of soft start technology is conducive to the development of the power system towards a highly networked direction, and at the same time promotes the continuous optimization of the configuration of the power grid to ensure that it is always running in a high-efficiency state. [0003] At present, the commonly used soft start technology at home and abroad can generally be divided into two types: electrical soft start and mechanical sof...
