Abstract
The utility model discloses a speed reducer transmission device of a combined sawing drilling machine saw frame with a hard alloy heavy rail, which can prevent slipping between an output shaft of a speed reducer and a belt wheel and comprises a belt wheel connected with a hub of an output shaft of a speed reducer. The output shaft of the speed reducer is peripherally fixed with the belt wheel via a key, a circular nut for axially fastening the belt pulley onto the output shaft of the speed reducer is mounted at the end of the output shaft of the speed reducer, and a circular nut backstop pad is arranged between the circular nut and the output shaft of the speed reducer. Transmission of torque between the output shaft of the speed reducer and the belt pulley is guaranteed in the manner of key connection, and the speed reducer transmission device thoroughly solves the problem of slipping between the output shaft of the speed reducer and the belt wheel.
Description
Technical field
The utility model relates to the carbide alloy heavy rail and unites saw drilling machine saw frame reductor transmission device.
Background technology
It is that heavy rail to universal rolling carries out scale, end face precision and boring processing that the carbide alloy heavy rail is united the main effect of sawing drilling machine.At present, adopting as shown in Figure 1 swelling cover to carry out propeller boss between the saw frame reductor power transmission shaft of this equipment and the toothed belt wheel connects, in actual production process, there is following problem: because the carbide alloy heavy rail is united the load that produced of saw drilling machine when the sawing heavy rail very big, the tensioning cover does not reach the closely fixing requirement that makes between speed reducer output shaft and the belt pulley, therefore cause speed reducer output shaft and belt pulley to produce skidding each other, and then the irregular variation of the rotating speed that causes reductor, reductor produces very big vibrations when causing sawing, cause saw blade to beat tooth and the sawing surface smoothness does not reach requirement, the reductor inner body damages; And speed reducer output shaft and belt pulley produce each other to skid and also can cause wearing and tearing of overlapping with tensioning of reductor, cause the tensioning cover to use.Because the existence of the problems referred to above, usually causing the carbide alloy heavy rail to unite the saw drilling machine can't work, and has both influenced the processing of heavy rail, has increased the Maintenance and Repair cost again.
The utility model content
The technical problem that the utility model solved provides a kind of carbide alloy heavy rail that skidding takes place between speed reducer output shaft and the belt pulley that prevents and unites saw drilling machine saw frame reductor transmission device.
The technical scheme that its technical problem that solves the utility model adopts is: the carbide alloy heavy rail is united saw drilling machine saw frame reductor transmission device, comprise the belt pulley that connects with the speed reducer output shaft propeller boss, undertaken circumferentially fixing between described speed reducer output shaft and the belt pulley by key, and be equipped with in the end of described speed reducer output shaft and be used for described Pulley shaft being provided with the round nut retaining pad between this round nut and this speed reducer output shaft to the round nut that is fastened on the speed reducer output shaft.
The beneficial effects of the utility model are: guaranteed the transmission of moment of torsion between speed reducer output shaft and the belt pulley thoroughly to have solved the skidding between speed reducer output shaft and the belt pulley by the mode of key connecting.
Description of drawings
Fig. 1 unites the structural representation of saw drilling machine saw frame reductor transmission device for existing carbide alloy heavy rail.
Fig. 2 unites the structural representation of saw drilling machine saw frame reductor transmission device for the application's carbide alloy heavy rail.
Be labeled as among the figure: speed reducer output shaft 1, belt pulley 2, swelling cover 3, key 4, round nut 5, round nut retaining pad 6.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Carbide alloy heavy rail is as shown in Figure 2 united saw drilling machine saw frame reductor transmission device, this device comprises the belt pulley 2 that connects with speed reducer output shaft 1 propeller boss, undertaken circumferentially fixing between described speed reducer output shaft 1 and the belt pulley 2 by key 4, and be equipped with in the end of described speed reducer output shaft 1 and be used for described belt pulley 2 is axially fastened round nut 5 on speed reducer output shaft 1, be provided with round nut retaining pad 6 between this round nut 5 and this speed reducer output shaft 1.This device has been guaranteed the transmission of moment of torsion between speed reducer output shaft 1 and the belt pulley 2 thoroughly to have solved the skidding between speed reducer output shaft 1 and the belt pulley 2 by the mode of key connecting.
