Description

Main shaft placement support for gearbox maintenance Technical Field The utility model relates to the field of gearbox maintenance, in particular to a main shaft placement support for gearbox maintenance. Background The main shaft of the gearbox is one of the core elements in the gearbox and plays important roles of transmitting power, supporting gears, a transmission device and the like. When the main shaft is installed or checked, the gearbox is required to be disassembled, the main shaft is placed on the support, then the main shaft can be installed or checked, because the support used nowadays is composed of the base and the support rod, after the main shaft is placed, the support rod is different in size from the central gap of the main shaft, so that the position of the main shaft can move, friction can occur between the edge position of the main shaft and the base, and after the position of the main shaft is changed, the main shaft with larger size can contact with the ground, abrasion can occur on the outer side of the main shaft, the main shaft is damaged, and the main shaft cannot be used later. Disclosure of utility model In order to make up the deficiency of the prior art, solve the position of the main shaft because the size of the supporting rod is different from the central gap size of the main shaft, cause the position of the edge of the main shaft to rub with the base, and the larger main shaft of some sizes is likely to contact with the ground after the position is changed, this can cause the abrasion of the outer side of the main shaft, cause the damage of the main shaft, cause the problem that can't be used subsequently, the utility model provides a main shaft placing support for the gearbox maintenance. The technical scheme includes that the main shaft placement support for gearbox maintenance comprises a base, wherein a supporting component is arranged on the outer side of the base and comprises a rotating disc rotatably connected to the inside of the base, four first sliding grooves are formed in the rotating disc, a first supporting rod is slidably connected to the inside of each first sliding groove, a sliding disc is fixedly connected to the bottom of each first supporting rod, eight balls are rotatably connected to the inside of the rotating disc, and the eight balls are divided into two groups.
