Description
Technical field
The utility model belongs to for making element rest in the field of mechanisms in precalculated position, is specifically related to a kind of running shaft damping mechanism.
Background technique
Axle is the mechanical parts that support rotary part turning round therewith transmits motion, moment of torsion or moment of flexure, and the part doing rotation motion in machine is just contained on axle.So the normal operation of axle is for extremely important machine.
Axle, in rotation process, particularly when two gears coordinate, if axle is subject to radial impact, then easily causes the situation of the gears meshing instability laid respectively on two axles, even can shut down by machine.
Model utility content
For the defect that above-mentioned prior art exists, the purpose of this utility model is the running shaft damping mechanism of the impact force providing a kind of energy absorption axes to be subject to.
For achieving the above object, the technical solution of the utility model is: running shaft damping mechanism, comprise driving gear, the rotatingshaft of driven gear and cooperation driven gear, wherein, the described driven gear side that keeps to the side is provided with the minor axis with its parallel to an axis, in addition, also be provided with bracket, sliding bar, stage clip and back-up ring, on the rotating shaft sheathed in the middle part of described bracket, and bracket has two relative trailing arms, two trailing arms all run through and is provided with sliding bar, described minor axis is between two sliding bars, the position of sliding bar between trailing arm and minor axis is all arranged with stage clip, sliding bar two ends are equipped with back-up ring.
When adopting technique scheme, when running shaft is subject to impact force, due on the rotating shaft sheathed in the middle part of bracket, so relatively rotate between bracket and rotatingshaft, minor axis is between two sliding bars, and the position of sliding bar between trailing arm and minor axis is all arranged with stage clip, so one end of sliding bar and minor axis offset, so two springs can be compressed, the relative driven gear of bracket swings, and impact force absorbs by spring in compression and recovery process.The part of impact force that the utility model energy absorption axes is subject to, ensures that the gear be meshed keeps stable engagement.
Further, described sliding bar is parallel with the end face of driven gear, spring compression and recovery process generation power in the plane parallel with driven gear end face, the power along rotatingshaft axis can not be produced, so bracket can not slide along rotatingshaft.
Further, described minor axis is connected with driven gear by clutch shaft bearing, minor axis is between two sliding bars and clamped, sliding bar is by minor axis driven rotary, when minor axis is connected with driven gear by clutch shaft bearing, there is no Relative friction between minor axis and sliding bar, the working life of minor axis can be extended.
Further, described bracket is connected by the second bearing with rotatingshaft, when rotatingshaft is hit power, bracket relatively rotates axle and rotates, and bracket is connected by the second bearing, and the friction between bracket and rotatingshaft is very little, carriage turns resistance is little, thus spring can absorb more impact force.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the utility model running shaft damping mechanism embodiment plan view;
Fig. 2 is the left view of Fig. 1.
Embodiment
As shown in Figure 1, a kind of running shaft damping mechanism, comprise driving gear 1, the rotatingshaft 2 of driven gear 3 and cooperation driven gear 3, wherein, as shown in Figure 2, driven gear 3 side that keeps to the side is provided with the minor axis 7 with its parallel to an axis, in addition, also be provided with bracket 4, sliding bar 8, stage clip 6 and back-up ring 5, be set on rotatingshaft 2 in the middle part of bracket 4, and bracket 4 has two relative trailing arms 41, two trailing arms 41 all run through and is provided with sliding bar 8, sliding bar 8 can slide by trailing arm 41 relatively, minor axis 7 is between two sliding bars 8, the position of sliding bar 8 between trailing arm 41 and minor axis 7 is all arranged with stage clip 6, sliding bar 8 two ends are equipped with back-up ring 5.
Minor axis 7 is connected with driven gear 3 by clutch shaft bearing, minor axis 7 is between two sliding bars 8 and clamped, sliding bar 8 is by minor axis 7 driven rotary, when minor axis 7 is connected with driven gear 3 by clutch shaft bearing, there is no Relative friction between minor axis 7 and sliding bar 8, the working life of minor axis 7 can be extended.
Bracket 4 is connected by the second bearing 9 with rotatingshaft 2, and when rotatingshaft 2 is hit power, bracket 4 relatively rotates axle 2 and rotates, bracket 4 is connected by the second bearing 9, friction between bracket 4 and rotatingshaft 2 is very little, and bracket 4 rotational resistance is little, thus spring can absorb more impact force.
Specific works flow process:
As shown in Figure 1, driving gear 1 rotates and drives the driven gear 3 be engaged with to rotate, when running shaft is subject to radial impact force, owing to being set on rotatingshaft 2 in the middle part of bracket 4, so relatively rotate between bracket 4 and rotatingshaft 2, minor axis 7 is between two sliding bars 8, the position of sliding bar 8 between trailing arm 41 and minor axis 7 is all arranged with stage clip 6, so one end of sliding bar 8 and minor axis 7 offset, minor axis 7 is clamped by two sliding bars 8, sliding bar 8 runs through trailing arm 41, sliding bar 8 two ends all connect back-up ring 5, so two springs can be compressed, and sliding bar 8 can be slided by the hole run through at trailing arm 41, bracket 4 relatively driven gear 3 swings, impact force absorbs by spring in compression and recovery process.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite not departing from the utility model structure; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
