Abstract
The invention discloses a gear shaft. The gear shaft comprises a gear and a shaft body which are separately arranged. A plurality of annular grooves are formed in the inner wall of the gear, annular grooves corresponding to the inner wall of the gear are also formed in the radial outer wall of the shaft body, the annular grooves in the inner wall of the gear and the annular grooves in the radial outer wall of the shaft body are used in cooperation to form annular cavities, power springs are arranged in the annular cavities, one end of each power spring is fixed to the inner wall of the gear, and the other end of each power spring is fixed to the outer wall of the shaft body. Through the technical scheme, the gear shaft has the advantages that the gear shaft is simple in structure and reasonable in technology; the power springs are additionally arranged between the gear and the shaft body so that the buffer effect can be achieved, and it is avoided that when the rotation speed of the gear increases fast, the acting force between the gear and the shaft body is very large, and consequentially a connecting mechanism between the gear and the shaft body is very prone to damage; besides, a gear sleeve made of rubber is additionally arranged on teeth of the gear, the rubber sleeve can also have a certain buffer effect, the teeth can be protected to a certain extent, and the service life of the gear is prolonged.
Description
Technical field
The present invention relates to transmission device technical field, refer to especially a kind of gear shaft.
Background technique
In gear transmission, transmission shaft will have good wearability, and the gear of transmitting torque requires to have good tooth portion's survivability (being called for short tooth anti-) and certain wear resistance.Mach gear shaft is an indivisible entirety, under a certain state, substantially has same physical and mechanical properties, and the anti-requirement of the requirement of axle to wear resistance and gear mesh tooth can not meet simultaneously like this, and higher with machining cost of production.
For addressing the above problem, it is CN 201982605 U that Chinese patent discloses notice of authorization number, name is called the patent of invention of powder metallurgy gear shaft, but when the operation of the gear shaft described in this technological scheme, in the time that gear improves rotating speed fast, very large of active force between gear and axle, so be easy to damage the bindiny mechanism between gear and axle.In addition, gear is under long working state, and the tooth of gear easily weares and teares, thereby easily occurs the phenomenon of de-tooth, has certain potential safety hazard.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of gear shaft, by set up clockwork spring between gear and axle, thereby play buffer function, avoid above-mentioned in the time that gear improves rotating speed fast, very large of active force between gear and axle, so be easy to damage the deficiency of the bindiny mechanism between gear and axle.
For solving the problems of the technologies described above, embodiments of the invention provide a kind of gear shaft, comprise gear and axle that split arranges, described gear inwall is provided with some circular grooves, described axle radial outer wall is also provided with the circular groove corresponding with gear inwall, and described gear inwall coordinates formation toroidal cavity with the circular groove of axle radial outer wall, in described toroidal cavity, be provided with clockwork spring, gear inwall is fixed in described clockwork spring one end, and the described clockwork spring the other end is fixed on axle outer wall.
As preferably, the tooth in described gear outside is socketed with geared sleeve.
As preferably, described geared sleeve is rubber sleeve.
The beneficial effect of technique scheme of the present invention is as follows: simple in structure; technology is reasonable; between gear and axle, set up clockwork spring; play the effect of buffering; avoid in the time that gear improves rotating speed fast; very large of active force between gear and axle; so be easy to damage the bindiny mechanism between gear and axle; on the tooth of gear, set up in addition the geared sleeve of being made by rubber; rubber sleeve also can play certain buffer function; tooth is had to certain protective action, improved the working life of gear.
Brief description of the drawings
Fig. 1 is a kind of gear shaft embodiment's of the present invention schematic cross-section.
Fig. 2 is the structural representation of Fig. 1 middle gear.
Embodiment
For making the technical problem to be solved in the present invention, technological scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
Existing a kind of gear shaft that provides is provided, as shown in Figure 1, comprise gear 2 and axle 1 that split arranges, described gear 2 inwalls are provided with some circular grooves, described axle 1 radial outer wall is also provided with the circular groove corresponding with gear 2 inwalls, and described gear 2 inwalls coordinate formation toroidal cavity 5 with the circular groove of axle 1 radial outer wall, in described toroidal cavity 5, be provided with clockwork spring 4, gear 2 inwalls are fixed in described clockwork spring 4 one end, and described clockwork spring 4 the other ends are fixed on axle 1 outer wall.
As shown in Figure 2, the tooth in described gear 2 outsides is socketed with geared sleeve 3, and described geared sleeve 3 is rubber sleeve.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of principle of the present invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
Claims (3)
