Embodiment Construction

[0020] A preferred embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings. However, the scope of protection of the present invention is not limited to the following examples, that is, any simple equivalent changes and modifications made based on the patent scope of the present invention and the content of the description are still within the scope of the patent of the present invention.

[0021] refer to figure 1 , 2 , a main drive input gear support structure for a micro-shield machine, including a planetary reducer 6 for receiving the work done by the motor to provide the main drive torque source, and the sun gear shaft center of the planetary reducer is used to connect the planet The torque of the reducer is transmitted to the input gear 5 of the ring gear of the main drive. The end of the input gear away from the reducer forms a cantilever end 51. The cantilever end of the input gear is provided with a half-open...

Abstract

The invention discloses a supporting structure for an input gear of a main drive for a micro shield construction machine. The supporting structure for the input gear of the main drive for the micro shield construction machine comprises a planetary speed reducer, and a sun gear axis input gear arranged on the planetary speed reducer, wherein one end away from the speed reducer, of the input gear, forms a cantilever end; a semi-open cantilever supporting is arranged on the cantilever end of the input gear; one end of the semi-open cantilever supporting sleeves the cantilever end of the input gear through a cantilever beam supporting bearing; and the other end of the semi-open cantilever supporting is fixed on a box body of the planetary speed reducer. According to the supporting structure for the input gear of the main drive for the micro shield construction machine, through arranging the semi-open cantilever supporting on the supporting bearing of the input gear, a double-supporting structure is equivalently formed, and has the advantages that the occupied installation space is less, the machining thereof is simple, the structure and the machining of the box body are simple, the maintenance is simple, the transmission reliability is high, the engagement loading condition of the gear is improved, prolonging for the service life of the main drive is benefited, and the like. The supporting structure for the input gear of the main drive for the micro shield construction machine is especially applicable to the main drive installed in the micro shield construction machine with a limited space.

Description

technical field [0001] The invention relates to the field of shield machine technology, in particular to a main drive input gear support structure for a micro shield machine. Background technique [0002] Shield machines are mainly used in tunnel construction. With the diversification of market demand, miniature shield machines (diameter≦3m) have become one of the development trends in the shield machine industry, especially for various shallow pipelines in the city. The circular shield machine with ultra-small diameter (≦1m) of the laid shield surface diameter is widely used in the field of municipal water supply and drainage pipelines and cable laying. [0003] The main feature of the micro-shield machine is the small radial size. Currently, the commonly used support forms of the main drive input gear shaft mainly include double support type and cantilever type. Among them, the double-support type has good stress conditions and high bearing capacity, and is the best choic...
