Inversed rotating reductor

Abstract

The invention discloses an inversed rotating reductor, and belongs to the technical field of reductors. The reductor is characterized in that a power producer of the reductor is arranged on the lower end of the whole reductor, the upper part of the power producer is connected with a braker, the upper part of the braker is connected with a speed changing mechanism, and the upper part of the speed changing mechanism is connected with a power input mechanism; the lower end of a braking connecting shaft is provided with a bearing, and the upper end of the braking connecting shaft is hermetically provided with a skeleton oil seal used for separating the inner cavity the braker from the inner cavity of a gear ring; and a dust cap is fixed on the upper end of a bearing base, and the dust cap is hermetically connected with an output gear wheel shaft. The reductor provided by the invention has the following beneficial effects: the inversion operation mode that a rotating reductor power input system is positioned at the lower part and a power output system is positioned at the upper part can be realized, and the operation is stable and reliable; the skeleton oil seal is used for separating the inner cavity of the braker from the inner cavity of the gear ring, thereby preventing a friction plate from being ablated; and the dust cap and a dustproof oil seal can prevent the outside sediment from invading, thereby effectively prolonging the service life of the reductor.

Description

technical field [0001] The invention relates to a rotary reducer and belongs to the technical field of reducers. Background technique [0002] The main parts of the existing slewing reducer for construction machinery are from top to bottom: power input system (such as hydraulic motor or electric motor), braking system, transmission system, output system (such as output gear) and other main four parts. The installation method is mainly that the power input system is on the top, and the power output system is on the bottom, and the output gear on the slewing reducer is meshed with the slewing support. However, in some cases, due to the limitation of the structural space of the main engine or other requirements, the slewing reducer must be installed upside down (such as the slewing system of a concrete pump truck), and the existing slewing reducer is difficult to meet such requirements. Because, when the existing reducer is inverted, because the internal transmission parts are...

Problems solved by technology

However, in some cases, due to the limitation of the structural space of the main engine or other requirements, the slewing reducer must be installed upside down (such as the slewing system of a concrete pump truck), and the existing slewing reducer is difficult to meet such requirements

Because, when the existing reducer is inverted, because the internal transmission parts are installed floatingly, it will inevitably cause axial slippage under its own gravity and interfere with the hydraulic motor; at the same time, when the rotary reducer is inverted, the transmission system will pass through Wear particles and other impurities worn down by long-term work can easily enter the space between the friction plate and the friction plate, resulting in ablation of the friction plate and causing brake failure
