Abstract
The utility model relates to a directly coupled type gear oil pump, which relates to a power device and belongs to the field of power machinery, particularly a power device for a pushing and raising hydraulic system of a turret machine. A connecting bracket and a shaft coupling are removed, and the length of the output end of a motor shaft is shortened by directly and fixedly installing the gear oil pump 1 on a motor flange end cover 8 which is connected with a motor as a whole. A notch 10 is arranged on the output end of the motor shaft 6 and is directly connected with a shaft extension 11 of an input shaft of the gear oil pump in a matching way according to the structure type of the input shaft 2 of the gear oil pump to ensure that the input shaft of the gear oil pump and the output shaft of the motor have the same coaxiality. The number of accessories is reduced, and the whole set of the device has the advantages of low cost, compact structure, small size and more convenient installation.
Description
Affiliated technical field: the utility model relates to a kind of power plant, and especially a kind of tower machine belongs to the dynamic power machine field with the power plant of jacking hydraulic system.
Background technique: at present, the power plant of tower machine jacking hydraulic system both domestic and external all adopt plain edition motor and gear oil pump to be connected with a pair of coupling by a hitch and realize transmission of power, it is more to connect annex, the input shaft of gear oil pump and the coaxality of motor output shaft are difficult to guarantee, very easily damage gear oil pump, and volume is big, installation bothers, the cost height.
Summary of the invention: the technical solution of the utility model is to connect the coaxality that annex realizes improving gear oil pump input shaft and motor output shaft by reducing and improving, to reduce the damage to gear oil pump.Technological scheme is as follows: gear oil pump directly is fixedly mounted on the motor flange end cap that is connected as a single entity with motor, deletion connecting rack and coupling, by shortening motor shaft output terminal length, and offer a notch according to the structural type of gear oil pump input shaft at the motor shaft output terminal and directly mate with the shaft extension of gear oil pump input shaft and connect, to guarantee the coaxality of gear oil pump input shaft and motor output shaft.
The straight boss shaft extension in the gear oil pump input shaft shaft extension side of can be, spline shaft extension, flat key cylinder shaft extension; The straight groove mouth in the motor shaft output terminal notch side of can be, or spline notch, or flat key cylinder notch.
Gear oil pump directly is fixedly mounted on the motor flange end cap, and the motor flange end cap is provided with boss and seam, establishes equally distributed tapped hole on the boss and is used for fastening gear oil pump, and seam is used for the location.Technical solution of the present utility model is by being directly installed on gear oil pump on the motor flange end cap, deletion connecting rack and coupling, shorten motor shaft output terminal length, the motor shaft output terminal is offered a notch and is directly mated with the shaft extension of gear oil pump input shaft and connect, guaranteed the coaxality of gear oil pump input shaft and motor output shaft, reduced annex quantity, reduced cost, package unit compact structure, volume are little, easier for installation.
Description of drawings: Fig. 1 is the gear oil pump motor connection diagram of prior art, Fig. 2 is the utility model structural representation, Fig. 3, Fig. 4 are embodiment 1 shaft extension 11 and notch 10 structural representations, Fig. 5, Fig. 6 are embodiment 2 shaft extension 11 and notch 10 structural representations, Fig. 7, Fig. 8 are embodiment 3 shaft extension 11 and notch 10 structural representations, and Fig. 9, Figure 10 are each embodiment's motor flange end cover structure schematic representation and A-A sectional view thereof.
Embodiment: preferred implementation is as follows.
Embodiment 1: the technological scheme of present embodiment is to connect the coaxality that annex realizes improving gear oil pump input shaft and motor output shaft by reducing and improving, to reduce the damage to gear oil pump.Technological scheme is as follows: gear oil pump 1 directly is fixedly mounted on the motor flange end cap 8 that is connected as a single entity with motor 9, connecting rack 7 and coupling 3 and 4 of prior art among deletion Fig. 1, by shortening motor shaft 6 output terminal length, and the shaft extension 11 of offering a notch 10 and gear oil pump input shaft at motor shaft 6 output terminals according to the structural type of gear oil pump input shaft 2 directly coupling connects, with the coaxality of assurance gear oil pump input shaft and motor output shaft.The straight groove mouth in the motor shaft output terminal notch side of being of present embodiment, the straight boss shaft extension in the corresponding gear oil pump input shaft shaft extension side of being.Motor flange end cap 8 is provided with boss 12 and seam 5, establishes equally distributed 4 tapped holes 13 on the boss 12 and is used for nut 14 fastening gear oil pumps, and seam 5 is used for the location.
Embodiment 2: present embodiment and embodiment's 1 difference is that the motor shaft output terminal notch 10 of present embodiment is the spline notch, and corresponding gear oil pump input shaft shaft extension 11 is the spline shaft extension.
Embodiment 3: present embodiment and embodiment's 1 difference is that the motor shaft output terminal notch 10 of present embodiment is flat key cylinder notch, and corresponding gear oil pump input shaft shaft extension 11 is a flat key cylinder shaft extension.
More than 3 embodiments all guaranteed the coaxality of gear oil pump input shaft and motor output shaft to have reduced annex quantity, reduced cost, package unit compact structure, volume are little, easier for installation.
