A single-input coaxial double-output reducer

Abstract

The invention relates to a single-input coaxial double-output speed reducer which comprises an input gear shaft, an output shaft I, a hollow output shaft II, a planetary gear speed reducing mechanism and a bevel gear diversion reversing mechanism, wherein the power is input through a sun gear on the input gear shaft; the power is transmitted into the output shaft I from a planet carrier by the planetary gear speed reducing mechanism; part of the power is directly output by the output shaft I, and the other part of the power is transmitted into the output shaft II sheathed on the output shaft I in an idle way by the bevel gear diversion reversing mechanism; the output shaft II can output the power at the speed equal to that of the output shaft I along the direction opposite to that of the output shaft I. The single-input coaxial double-output speed reducer is simple in structure and reasonable in design, and can realize the transmission requirements of mixing equipment to a concentric double-shaft mixing system only by using a set of powder device, thus greatly saving the using space and lowering the production cost.

Description

technical field [0001] The invention relates to a gear transmission device, in particular to a speed reducer for stirring equipment. Background technique [0002] Stirring equipment is a key equipment widely used in technical fields such as machinery, chemical industry, medicine, metallurgy and food. During the working process, it is often accompanied by phase transition, heat transfer and viscosity change. In the above process, the stirring mechanism generally adopts a single central dispersion paddle, a single near-wall anchor paddle or a frame paddle. More evenly, there are also internal and external double-screw propellers. However, the above stirring methods cannot guarantee the uniformity of stirring during the working process, and the stirring effect varies with the viscosity of the material. Therefore, the use of concentric double-shaft stirring system has become a new development direction. [0003] The concentric twin-shaft mixing system uses two inner and outer ...

Problems solved by technology

However, the above stirring methods cannot guarantee the uniformity of stirring during the working process, and the stirring effect varies with the viscosity of the material. Therefore, the use of concentric double-shaft stirring system has become a new development direction.

[0003] The concentric twin-shaft mixing system uses two inner and outer stirring paddles with the same axis. Generally, the central part uses a central dispersing paddle, and the periphery uses anchor paddles, frame paddles or screw belt paddles. This requires that the transmission device can output two movements at the same time. For this reason, general mixing equipment uses two sets of transmission systems to drive the inner and outer stirring paddles to work, resulting in a large and complicated structure.
