Description

Technical Field

[0001] The utility model relates to the technical field of power take-offs, in particular to a power take-off of a rotary transmission support structure. Background Art

[0002] The essence of a power take-off is one or more sets of speed gears, which are generally composed of a gearbox, a clutch, and a controller. They are connected to the low-speed gear of the gearbox or the output shaft of the auxiliary box, and to the input shaft of a power take-off device such as a lifting pump, to output power to an external working device. The use of a power take-off can prevent gear shifting. Since a gear structure is provided inside the power take-off and the gears mesh with each other, in order to reduce the friction at the gear meshing point, the interior of the power take-off is generally filled with lubricating oil, which is used to achieve a lubricating effect.

[0003] The invention patent with the authorization announcement number CN103303139B discloses a power take-off device, including a power take-off output shaft and a housing supporting the power take-off output shaft; the cross section of the inner cavity of the housing is circular; one end of the power take-off output shaft is provided with a power take-off gear for meshing with the gear of the engine gear chamber, and the other end is provided with an internal spline for matching with the external spline of the power device; the power take-off output shaft is eccentrically arranged with the housing. Since the power take-off output shaft and the housing are eccentrically arranged, when the transmission speed ratio of the power take-off device needs to be changed according to the speed requirement of the power device, it is only necessary to change the number of teeth of the power take-off gear of the power take-off output shaft according to the needs, and correspondingly change the eccentric position of the power take-off output shaft relative to the housing, and the structure of the eccentric arrangement of the power take-off output shaft and the housing is easy to implement.

[0004] Although the above technical solution has the advantage of adjusting the transmission speed ratio of the power take-off without changing the installation position, the friction during the meshing of the gears will cause some surface debris and impurities to fall off. In addition, foreign impurities will also enter the inside of the power take-off. At this time, the impurities mixed in the lubricating oil will continue to get stuck in the gears as the gears rotate, causing the gear parts to continue to wear seriously. It is impossible to filter the lubricating oil in time, which is not conducive to filtering the impurities that fall into the lubricating oil in time, causing inconvenience to the user. In view of this, we propose a power take-off with a rotating transmission support structure. Utility Model Content

[0028] In this embodiment, the terminal tube body of the delivery pipe 22 is located above the filter 273, and the return pipe 24 is located below the filter 273, so that the lubricating oil can be filtered by the filter 273 and then returned to the power take-off body 1.
