Submersible Electric Mixer

The submersible electric mixer is developed to improve the suction concentration of the slurry pump. It is suitable for different fields such as mine tail discharge, steel mill, power plant, slag discharge, sea port sand extraction, river sand extraction, river dredging, water conservancy engineering, sewage treatment and so on.

The submersible electric mixer is a novel transmission device that adopts the K-H-V planetary transmission principle with small tooth difference. The difference in the number of teeth between the sun gear (pin gear) ZZ and the planetary gear (cycloidal gear) ZB is 1, namely: ZZ-ZB=1

Transmission process:

A double eccentric sleeve with dislocation by 180° is installed on the input shaft, and two rolling bearings called as the rocker arm are installed on the eccentric sleeve, forming Hmechanism. The center hole of two cycloid gear is the roller path of the rocker arm bearing on the eccentric sleeve. The cycloid gear is engaged with a group of needle gear in annular arrangement on the pin wheel, so as to form the inner engaged reducer with gear difference as a tooth.(In order to reduce friction, the needle gear is inserted with the needle gear sleeve in the reducer with small speed ratio).

When the input shaft rotates by a circle with the eccentric sleeve, restricted by the tooth profile curve on the cycloid gear and needle gear on the pin gear, motion of the cycloid gear becomes plane motion with revolution and spinning. For forward rotation of the input shaft by a circle, the eccentric sleeve also rotates by a circle. The cycloid gear rotates by a tooth in the opposite direction for deceleration. By means of W output mechanism, the low-speed spinning motion of the cycloid gearis transferred to the output shaft through the pin shaft, so as to obtain lower output speed.

Features and Main Mechanisms:

· High speed ratio and high rotating speed

Single machine transmission, reaching reduction ratio of 1:71 and efficiency above 90%.

· Stable operation and low noise

More number of teeth of the cycloid needle gear. Large overlapping coefficient and organic part balance principle, so that vibration and noise are restricted to the minimum degree.

· Reliable use and long life

The main parts adopt the high carbon chromium steel material. After quenching treatment, (HRC58 62)obtains high strength. Moreover, some transmission contact ad pts rolling friction. Therefore, it is durable with long life.
