The mechanism can effectively resolve and utilize the effect of the axial force of the swash plate; and through the structure, the swash plate mechanism rotates stably and smoothly, and equipment runs stably.
Description
Technical field
The utility model relates to and a kind of to-and-fro motion is converted to the oblique disk structure of rotation, particularly relates to a kind of swash plate duplex bearing positioning means.
Background technique
Oblique disk structure can be converted to rotation with to-and-fro motion, usually be used in such as Stirling engine or other occasion of rotatory force need to be provided, the main structure of swash plate body comprises the main body swash plate, but be connected with the connecting rod of the some reciprocating actions that are evenly distributed in a side of swash plate, the swash plate center is then by tiltedly cylinder connection one rotating shaft, these connecting rods generally provide power by some for pressing system, has certain progressive error during work, meeting is expanding-contracting action successively, so that the swash plate corresponding position is along the axial reciprocating of these connecting rod restrictions, be reacted to swash plate on the whole, just formed and circumferentially moved along the inclination of a direction according to certain rules, and circumferentially action passes to rotating shaft by oblique cylinder, will drive rotating shaft along a circular motion, finally passes the process that has just realized to-and-fro motion is converted to rotation.Because swash plate is subject to the responsive to axial force of connecting rod in movement process, but the effective force that finally passes to oblique cylinder is rotatory force, the axial force that swash plate is subject to does not belong to the effective force of needs, therefore except rotatory force, axial force is wasted, and because the existence of axial force, can impose on oblique cylinder, rotating shaft and other relational structure pressure, cause to be subjected to force unbalance, and may so that rotation is not steady, normal operation be impacted.
The model utility content
The technical problems to be solved in the utility model provides a kind of axial force that can effectively dissolve, utilize swash plate, makes the swash plate duplex bearing positioning means of stressed and stability of rotation.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of swash plate duplex bearing positioning means, comprise swash plate, tiltedly cylinder and rotating shaft, wherein tiltedly be provided with and its axial rotary shaft hole at an angle near the cylinder center, rotating shaft is installed in this rotary shaft hole, the swash plate middle part is provided with through hole, tiltedly cylinder is installed in this through hole, tiltedly be arranged with two taper roller bearings outside the cylinder, described swash plate both sides are provided with holding cavity along through hole, described two taper roller bearings are respectively in two holding cavities, and by outer ring separately described through hole is clipped in the middle, end at described oblique cylinder is provided with the boss that blocks taper roller bearing, the other end at described oblique cylinder is equipped with a locking nut, and this locking nut cooperates this boss that described two taper roller bearings and swash plate lock are fitted together.
The beneficial effects of the utility model: the utility model adopts two taper roller bearings that swash plate and oblique cylinder are fixed together, so that the axial force that swash plate produces at work is the tiltedly rotation of cylinder by the taper roller bearing transmission, dissolve, utilize the effect of sloping tray axial power to reach effectively, by structure of the present utility model, so that swash plate body rotates more steady and smooth, the equipment running is also more stable.
Description of drawings
In order to be illustrated more clearly in the technological scheme among the utility model embodiment, the accompanying drawing of required use was done simple declaration during the below will describe embodiment.Obviously, described accompanying drawing is a part of embodiment of the present utility model, rather than whole embodiment, and those skilled in the art can also be according to other design proposals and the accompanying drawing of these accompanying drawings acquisitions under the prerequisite of not paying creative work.
Fig. 1 is fractionation structural representation of the present utility model;
Fig. 2 is cross-sectional view of the present utility model.
Embodiment
Be clearly and completely described below with reference to embodiment and the accompanying drawing technique effect to design of the present utility model, concrete structure and generation, to understand fully the purpose of this utility model, feature and effect.Obviously; described embodiment is a part of embodiment of the present utility model, rather than whole embodiment, based on embodiment of the present utility model; other embodiments that those skilled in the art obtains under the prerequisite of not paying creative work all belong to the scope that the utility model is protected.
With reference to Fig. 1, Fig. 2, a kind of swash plate duplex bearing positioning means that provides of the present utility model, comprise swash plate 1, tiltedly cylinder 2 and rotating shaft 3, wherein tiltedly be provided with and its axial rotary shaft hole at an angle near cylinder 2 centers, rotating shaft 3 is installed in the rotary shaft hole, swash plate 1 middle part is provided with through hole 11, tiltedly cylinder 2 is installed in this through hole 11, because of the axial direction of swash plate 1 and oblique cylinder 2 identical, receive successively the axial reciprocating power of order and during accompany movement, pass to oblique cylinder 2, so that tiltedly cylinder 2 moves along a circumference deflection successively at swash plate 1, and this deflection moves through the rotary shaft hole 21 of proper angle and passes to rotating shaft 3, just so that rotating shaft 3 rotatablely move.
Stress for reasonable corresponding swash plate 1 axial action generation, the utility model tiltedly is being arranged with two taper roller bearings 4 outside the cylinder 2, and two holding cavities 12 are offered respectively along through hole 11 in swash plate 1 both sides, two taper roller bearings 4 are respectively in two holding cavities 12, simultaneously, the bottom surface of two taper roller bearings 4 by holding cavity 12 be spacing, by separately bearing outer ring through hole 11 is clipped in the middle, so rotation and the swash plate of oblique cylinder 2 self can be come in 1 minute, be independent of each other; And in order to fix associated components, can be provided with the boss 21 that blocks taper roller bearing 4 at an end of oblique cylinder 2, the other end at oblique cylinder 2 arranges outside thread, by outside thread one locking nut 5 is installed, because tiltedly cylinder 2 sides that boss 21 is set cooperate a taper roller bearing 4 to be clamped in a side of swash plate 1, and tiltedly cylinder 2 cooperates a taper roller bearing 4 to be clamped in the opposite side of swash plate 1 by locking nut 5, and integral body just cooperates boss 21 that two taper roller bearings 4 and swash plate 1 lock are fitted together by locking nut 5.
Said structure, be equivalent to by two taper roller bearings 4 swash plate 1 and oblique cylinder 2 are assembled together, so that tiltedly cylinder 2 can center on its common axial rotation with respect to swash plate 1, but limited the relative action of other directions, like this when swash plate 1 is done axial perseveration, tiltedly cylinder 2 carries out the motion of certain track except following swash plate 1, can also the axial force of its transmission be converted into rotatory force by taper roller bearing 4, as seen by this structure, can reach effectively and dissolve, utilize the effect of swash plate 1 axial force, so that the action of swash plate body is more smooth and easy, the equipment running is also more stable.
Certainly, the invention is not limited to above-mentioned mode of execution, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, the modification that these are equal to or replacement all are included in the application's claim limited range.
