Embodiment

[0016] Embodiment: This device is further described with this embodiment. In this example, seawater is used as the medium to test the pressure of the pipeline. During the pressure test, the seawater needs to be treated and a certain amount of chemical agents are added. Since the reasonable way to add the agent is to decrease with time, its change curve is as follows Figure 4 As shown, so the medicament dosing pump is also required to adjust the speed according to this curve (see Figure 5 ). The composition of the motor stepless automatic deceleration device designed according to this deceleration curve is as follows: figure 1 shown. The motor 7 is a micro DC motor GA16Y050-128 type, and the No. 1 battery for power supply; the deceleration mechanism 5 is a PL40 precision planetary reducer with three stages of reduction; the excitation governor 1 is a JD1A-40 type; the potentiometer gear 2 is Φ40mm, Number 2.5, gear with 16 teeth; incomplete meshing gear is Φ20mm, module 2...

Abstract

The reduction apparatus includes following parts and structures: through a shaft coupling, a shaft of electrical motor is connected to a reduction gears; through another shaft coupling, output shaft of the reduction gears is connected to external transmissive incomplete engaging gear unit, output shaft of which is connected to shaft of excitation speed regulator. Incomplete engaging gear unit as an external transmission is composed of incomplete engaging gear accorded with a deceleration curve, and a potentiometer gear wheel. Features are: simple structure, easy of use and maintenance, low cost, reliable and durable.

Description

technical field [0001] The invention is a stepless automatic deceleration device for a motor stepless and automatic deceleration according to the deceleration curve. It relates to the technical field of electric motors and transmission devices. Background technique [0002] As we all know, the output speed of the motor can be adjusted steplessly after using the excitation speed regulating device and the frequency conversion speed regulating device, but the output speed generally required to be kept constant during operation. But at some point, it is more economical to use a motor stepless automatic deceleration with deceleration curve output device to complete the work. [0003] For example, the seawater pressure test is used in the pipeline project in western Libya. The seawater is treated with a special agent and then enters the pipeline. This special agent is composed of a very polar molecule. "Hydrophobic end", the other pole has a stronger affinity for the surface of ...
