Abstract
The utility model discloses a hard tooth surface gear in a gearbox, wherein the hard tooth surface gear comprises a tubular first stage gear, one side of the first stage gear is provided with a second stage gear of the hard tooth surface, the second stage gear is connected with the sleeve of the first stage gear by a flat key or a spline, the two ends of the sleeve are respectively provided with an annular groove; one annular groove is mounted with a spring check ring to fix the second stage gear and the other annular groove is applied to mounting a shifting fork. The transmission moment force of a first stage transmission gear is small, so in order to reduce the processing cost of products, gears with hard tooth surface are unnecessary to manufacture; the transmission moment force of a second stage transmission gear is comparatively large, so the tooth surface of the gear is hardened, so not only the service life and the transmission efficiency of a speed reducer are improved, but also the manufacturing cost of the speed reducer is not increased obviously. Meanwhile, the second stage transmission gear can be changed independently in case of abrasion and damage, therefore the service life of the speed reducer is prolonged.
Description
Technical field
The utility model relates to a kind of driving gear, is specifically related to a kind of hardened face gear that is applied in the gearbox.
Background technique
Driving gear in the retarder is the gear of the common hardness flank of tooth in the prior art, does not need that generally gear teeth face is carried out surface hardening and handles.This gear is less for some transmission powers, and the retarder of long-time continuous running is no problem.Yet in actual use, some transmission power is bigger, or starts frequent retarder, and the tooth surface abrasion that occurs gear through regular meeting is serious, problems such as transmission efficiency reduction, even the phenomenon of broken teeth appears.So, be necessary to improve the hardness of the driving gear flank of tooth in the retarder according to particular job requirement of some retarders.
The model utility content
The purpose of this utility model is to overcome the defective that exists in the prior art, designs the higher hardened face gear of a kind of retarder middle gear surface hardness.
For achieving the above object, the technical solution of the utility model provides the hardened face gear in a kind of gearbox, it is characterized in that, described hardened face gear comprises the one-level gear of sleeve shape, side at described one-level gear is set with the secondary gear that is provided with the hard flank of tooth, described secondary gear is connected with the sleeve of described one-level gear by flat key or spline, two ends at described sleeve are respectively equipped with circular groove, in circular groove check ring is housed therein and is used for fixing described secondary gear, another circular groove is used to install shift fork.
Wherein, optimized technical scheme is, is provided with keyway in described sleeve, and described keyway is used for being connected with transmission shaft by flat key or spline.
In order to make gear stable drive noise in retarder low, optimized technical scheme comprises that also described one-level gear and/or secondary gear can or be helical gear for spur gear.
For fear of the movement interference between driving gear, optimized technical scheme also comprises, is provided with annular gasket between described one-level gear and secondary gear.
In order to alleviate driving gear weight, be convenient to the dynamic balancing of adjusting gear, optimized technical scheme also comprises, is provided with annular groove and/or is evenly equipped with through hole on the two sides of the driving cog of described secondary gear and the tooth hub between the mounting hole.
Advantage of the present utility model and beneficial effect are: because the structure that the utility model is made of one formula with original one-level driving gear and secondary driving gear as shown in Figure 1, change into one-level driving gear and secondary driving gear are made split type structure.Because one-level driving gear moment of transmission in speed reducer is less in order to lower the processing cost of product, do not need to make the gear of the hard flank of tooth, and the moment of secondary driving gear transmission is bigger, so need carry out cure process to its flank of tooth, carries out high frequency hardening processing etc. as the flank of tooth to gear.The working life and the transmission efficiency of retarder had so both been improved, simultaneously the manufacture cost of retarder is increased significantly, and when the secondary driving gear wearing and tearing occur or damages, only need, can make obtain prolonging the working life of retarder so again its independent replacing.
Description of drawings
Fig. 1 is the existing schematic representation that one-level driving gear and secondary driving gear is made of one the formula structure;
Fig. 2 is the schematic representation that the utility model is made one-level driving gear and secondary driving gear split-type structural;
Fig. 3 is at the schematic representation that has installed gasket construction on the basis of Fig. 2 between one-level driving gear and secondary driving gear additional.
Among the figure: 1, one-level gear; 2, secondary gear; 3, flat key; 4, sleeve; 5, circular groove; 6, check ring; 7, keyway; 8, annular gasket; 9, annular groove.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
The utility model is the hardened face gear in a kind of gearbox, this hardened face gear comprises the one-level gear 1 of sleeve shape, side at described one-level gear 1 is set with the secondary gear 2 that is provided with the hard flank of tooth, described secondary gear 2 is connected with the sleeve 4 of described one-level gear 1 by flat key 3, be respectively equipped with circular groove 5 at the two ends of described sleeve 4, in circular groove 5 check ring 6 is housed therein and is used for fixing described secondary gear 2, another circular groove is used to install shift fork.
In the utility model, in described sleeve 4, be provided with keyway 7, described keyway is used for being connected with transmission shaft by flat key or spline.
In the utility model, in order to make gear stable drive noise in retarder low, described one-level gear 1 and/or secondary gear 2 can also can be selected helical gear for use for spur gear.
In the utility model,, between described one-level gear 1 and secondary gear 2, be provided with annular gasket 8 for fear of the movement interference between driving gear.
In the utility model, in order to alleviate driving gear weight, be convenient to the dynamic balancing of adjusting gear, be provided with annular groove 9 and/or be evenly equipped with through hole on the two sides of the driving cog of described secondary gear 2 and the tooth hub between the mounting hole.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
