Embodiment Construction

[0009] The present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings.

[0010] A gear reducer that can be installed in the shell of a submersible mixer is characterized in that the transmission structure of the gear reducer is a three-axis type; the input shaft and the output shaft are on the same axis; and the parallel shaft helical gears perform two-stage reduction.

[0011] The gear reducer box ① is made of aluminum alloy. The lower side of the box chamber and the rear box room are closed, and there are windows for installing gears and bearings on the upper side of the box body; three sets of holes parallel to the axis are arranged on the front wall, middle wall, and rear wall of the box body, and the three sets of axes One set of axes in the center of the cylinder is coaxial with the center line of the cylindrical box, and the other two sets are the intermediate shafts arranged eccentrically and symme...

Abstract

The invention aims to design a traditional submersible mixer originally adopting a multi-P (such as 6P, 8P and 12P) motor direct-connection type driving structure into 4P motor drive by improving a product structure. A gear reducer is additionally arranged in a submersible mixer shell, the advantages that a 4P motor has good comprehensive performance and the transmission efficiency of a helical gear can reach 99% are utilized, and meanwhile, the mechanical principle of gear reduction and torque increasing is utilized, so that the rotation speed of an impeller on an output shaft reaches to be basically the same with the rotation speed of an impeller of the direct-connection type traditional submersible mixer of 12P, 8P and 6P after the 4P motor drives the gear reducer, and a novel submersible mixer with a power saving function and a novel structure is designed through mechanical-electrical integration combination.

Description

technical field [0001] The invention belongs to the field of water treatment equipment, in particular to a gear reducer that can be installed in the housing of a submersible mixer; Background technique [0002] Submersible mixers are widely used in municipal and industrial sewage treatment processes. Due to the need for continuity in water treatment processes, submersible mixers must run continuously for a long time without stopping, so the power consumption is extremely high. [0003] At present, most of the domestic traditional submersible mixers use AC asynchronous motors (hereinafter referred to as "AC asynchronous motors" for short) to directly connect to the impeller. The submersible mixer is graded according to the diameter of the impeller and uses a multi-pole (hereinafter "pole" is replaced by P) motor to achieve the rated speed to provide a torque power source for the impeller of the mixer. Small power (4Kw and below) traditional submersible mixer (impeller) The m...
