Abstract
The utility model discloses a gear milling tool rest gear transmission clearance removing mechanism. The gear milling tool rest gear transmission clearance removing mechanism comprises an oil cylinder structure and a pull rod shaft fixedly arranged with a second transmission gear of a gear milling tool rest, and the pull rod shaft is in rotating fit with and axially fixed with an oil cylinder piston. Pressure oil is injected from an oil cylinder oil injection hole, and the piston moves upwards slightly to push the second transmission gear of the gear milling tool rest to slide slightly on a shaft. Due to the fact that the second transmission gear and a first transmission gear meshed with the second transmission gear are both helical gears, the first transmission gear and the second transmission gear are completely clamped, a transmission clearance is removed, therefore transmission noise of a gear pair is reduced, the service life of the gear pair is prolonged, and gear milling accuracy is improved. In addition, through the action of an end face bearing, the piston cannot influence rotating of the second transmission gear.
Description
Technical field
The utility model relates to a kind of milling slide, and clearance mechanism is eliminated in particularly a kind of milling slide gear drive.
Background technology
Mill teeth machine carriage arbor transmission system of the prior art as shown in Figure 2, the whole transmission of milling slide is from motor, the rotation of driven by motor belt wheel, the belt wheel secondary rotation of driven gear again divides the transmission of two-way one-level level to go down at last to milling cutter then.Problems such as existing transmission mechanism is not all eliminated the device in gap, so just makes milling slide each gear pair in process can rebound under the effect of cutting force, causes gear pair transmission noise big, fragile, and the mill teeth precision is low.Drive gap is accumulated since the 3rd travelling gear, then until milling cutter, again from milling cutter to second travelling gear, and second travelling gear and the 3rd travelling gear are installed on the axle, a closed loop driving-chain has been formed in the two-way transmission in fact on version, therefore as long as the some links in closed loop have been eliminated drive gap, the gear pair drive gap in the so whole driving-chain process has all been eliminated.Therefore, be necessary to work out a kind of milling slide gear drive and eliminate clearance mechanism, can eliminate the drive gap on the milling slide.
The utility model content
In view of this, the purpose of this utility model provides a kind of milling slide gear drive and eliminates clearance mechanism, can eliminate the gear-driven gap of milling slide.
The purpose of this utility model is achieved through the following technical solutions:
Clearance mechanism is eliminated in a kind of milling slide gear drive, comprises a cylinder structure and a pull rod shaft that fixedly installs with milling slide second travelling gear, and described pull rod shaft and oil cylinder piston are rotatably assorted and axial restraint;
Further, described cylinder structure comprises housing and piston, described housing is a tube-in-tube structure, described tube-in-tube structure inwall is provided with two annular table, described annular table is provided with sealing ring, described piston outer wall and annular table are slidingly matched, and the pouring orifice of described cylinder structure is arranged between two annular table;
Further, described sleeve lining is provided with annular edge, and described pull rod shaft is passed through the end face bearing fixing on the annular edge.
The beneficial effects of the utility model are: the utility model is from oil cylinder pouring orifice injection pressure oil, upwards slight second travelling gear that promotes milling slide that moves of piston slightly slides on axle, because second travelling gear and with first travelling gear of its engagement all be helical gear, therefore, block fully between first travelling gear and second travelling gear, promptly eliminated drive gap, by the effect of end face bearing, piston can not have influence on the rotation of second travelling gear and the 3rd travelling gear yet in addition.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can realize and obtain by following specification.
Description of drawings
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail, wherein:
Fig. 1 is the utility model structural representation;
Fig. 2 is a mill teeth machine carriage arbor transmission system schematic diagram;
Among the figure, 1, first travelling gear, 2, second travelling gear, the 3, the 3rd travelling gear, 4, housing, 5, piston, 6, first spacer, 7, the end face bearing, 8, second spacer, 9, locking nut, 10, pull rod shaft.
The specific embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment only for the utility model is described, rather than in order to limit protection domain of the present utility model.
Clearance mechanism is eliminated in a kind of as shown in the figure milling slide gear drive, comprise pull rod shaft 10, described pull rod shaft 10 is locked on the piston 5 by locking nut 9, first spacer 6, second spacer 8, end face bearing 7, therefore pull rod shaft 10 is rotatably assorted and axial restraint with piston 5, the described piston 5 outer housings 4 that are provided with, described housing 4 is formed cylinder structure with piston 5, and described pull rod shaft 10 is bolted to connection with second travelling gear 2 of milling slide.
Present embodiment is from oil cylinder pouring orifice injection pressure oil, piston 5 is upwards slight to be moved, second travelling gear 2 of milling slide slightly slides on axle, because first travelling gear 1 and second travelling gear 2 all are helical gears, therefore, block fully between first travelling gear 1 and second travelling gear 2, promptly eliminated drive gap.By the effect of end face bearing 7, piston 5 can not have influence on the rotation of second travelling gear 2, the 3rd travelling gear 3 yet.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of the technical program, it all should be encompassed in the middle of the claim scope of the present utility model.
