Abstract
The utility model provides a quick detachable axle and structure of hole fit clearance elimination, consolidates the screw including taking the straight hole part, main shaft, the interior awl cover that rises, the outer cone cover that rises, and the gland, the gland screw is provided with the gland and takes the straight hole part on the main shaft, and the interior cover that rises of boring of assembly between straight hole part and the main shaft is taken to the assembly outer cone cover that rises between main shaft and the gland, and interior awl rises, and it rises with the outer cone to overlap set is connected. The utility model discloses an awl cover and the outer cone cover that rises that rises in not grooved, interior awl rise cover and hole assembly, outer cone rise cover and axle assembly, through the cover that rises of awl in bulldozing, the laminating outer cone cover that rises, thereby production deformation elimination shaft hole fit clearance. The axle can design into the straight section with hole cooperation section, and its machining precision requires lowlyer with hole taper fit's machining precision than traditional axle, and the manufacturability is better. In addition, this kind of fit clearance eliminates that the structure adopts, and to rise by the cover different with traditional cover that rises, and processings of slotting on it can be guaranteed more traditional the rising of deformation and overlap more evenly to realize more delicate cooperation and transmission.
Description
Technical field
The utility model relates to the structure that a kind of easily detachable shaft hole matching gap is eliminated.
Background technique
Often relate to the elimination in shaft hole matching gap in a lot of industry especially machinery industry, and require quick detachable, traditional method is all designed with the axle matched in hole to be processed into the elimination that tapering carries out matching gap.But when run into coordinate section in the centre of axle and shaft shoulder span less situation time, this conventional method of more difficult employing.In addition, when the disc parts datum hole designed is straight hole, when dynamic balancing measurement, when must eliminate the gap of the axle on associated dynamic balancing machine, just cannot adopt this traditional structure.
Summary of the invention
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, the structure that a kind of easily detachable axle and hole matching gap are eliminated is provided, not only can be used for the elimination of stub bore and axle matching gap, be particularly useful for the centre of axle and shaft shoulder span is less need eliminate hole and axle matching gap, the more difficult occasion adopting tradition to eliminate shaft hole matching gap structure, and the occasion such as disc parts dynamic balancing measurement, Applicable scope is wider.
The utility model solves the technological scheme that its technical problem adopts:
The structure that a kind of easily detachable axle and hole matching gap are eliminated, comprise band straight hole part, reinforce screw, main shaft, inner cone ringfeder, outer cone ringfeder, gland, gland screw, main shaft is provided with gland and band straight hole part, assemble outer cone ringfeder between main shaft and gland, assemble inner cone ringfeder between band straight hole part and main shaft, inner cone ringfeder is connected with outer cone ringfeder.
As preferred version of the present utility model:
Gland screw is provided with between described gland and main shaft.
Described gland becomes threaded section with spindle design.
Reinforcing screw is set between described main shaft and straight hole part.
The beneficial effects of the utility model are: the inner cone ringfeder and the outer cone ringfeder that adopt unslotted, and inner cone ringfeder and hole are assembled, and outer cone ringfeder and axle assemble, and by pushing inner cone ringfeder, laminating outer cone ringfeder, produces distortion thus eliminate shaft hole matching gap.Axle can be designed to straight section with the hole section of cooperation, and its requirement on machining accuracy is lower than the machining accuracy of traditional axle and hole taper fit, and manufacturability is better.In addition, it is different from traditional ringfeder that this matching gap eliminates the ringfeder that structure adopts, and it does not carry out slot treatment, can ensure to be out of shape more traditional ringfeder evenly, thus the more accurate cooperation of realization and transmission.
Accompanying drawing explanation
Fig. 1 is sectional structural map of the present utility model.
In figure: 1-is with straight hole part, and 2-reinforces screw, 3-main shaft, 4-inner cone ringfeder, 5-outer cone ringfeder, 6-gland, 7-gland screw.
Embodiment
Below in conjunction with the accompanying drawing 1 in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not paying the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, if the gland screw 7(main shaft 3 evenly tightened on gland 6 and gland 6 are designed to threaded section, now do not need this gland screw 7, only gland need be screwed), the end face of gland 6 is made to be close to the large end face of outer cone ringfeder 5, under the effect of outer cone ringfeder 5, inner cone ringfeder 4 produces distortion, eliminate the gap between inner cone ringfeder 4 and band straight hole part 1, reaction force makes again outer cone ringfeder 5 produce distortion simultaneously, eliminate the gap between outer cone ringfeder 5 and main shaft 3, owing to being that tapering is fitted between inner cone ringfeder 4 and outer cone ringfeder 5, there is not gap, band straight hole part 1 is so just made to be eliminated by the distortion of inner cone ringfeder 4 with outer cone ringfeder 5 with the matching gap of main shaft 3.Gap eliminate after, if need transmit comparatively high pulling torque time, tighten reinforce screw 2, play reinforcing and transmitting torque effect.When disassembly is desired, only need unclamp corresponding screw can pull down easily.Shown in Fig. 1 is the inside and outside cone ringfeder of biserial, if spatial position has in limited time, can adopt single-row inside and outside cone ringfeder.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
