Abstract
The utility model relates to a kind of gear clearance cancellation element, it comprises transmission shaft, be arranged on the master gear on transmission shaft, be arranged on transmission shaft is close to master gear conjunction from gear, torsion spring, master gear and adopt same gear to be split to form through Linear cut from gear, described is provided with the first fixed hole from gear, described transmission shaft is near being provided with the second fixed hole from one end of gear, and described one end is arranged in the first fixed hole, and the other end is arranged in the second fixed hole.After adopting above structure, the utility model compared with prior art has the following advantages: torsion spring is arranged on transmission shaft and between gear, structure is simple, and only need to establish fixed hole at transmission shaft with from gear, easy for installation, cost is low.
Description
Technical field
The utility model belongs to technical field of mechanical transmission, especially a kind of gear clearance cancellation element.
Background technique
Existing gear clearance cancellation element, be mostly that gear is cut into two-part, gear fixes torsion spring, utilize the pulling force of torsion spring to realize side set, State Intellectual Property Office website discloses a kind of new gear to disappear clearance mechanism, it comprises transmission shaft, it is provided with actuation gear, side set gear, torsion spring, and actuation gear and side set gear adopt same gear to be split to form through Linear cut, torsion spring is embedded between Double-gear, this complex structure, and install inconvenient, cost is high.
Model utility content
Technical problem to be solved in the utility model is: the defect overcoming above prior art, provides the gear clearance cancellation element that a kind of structure is simple, easy for installation, cost is low.
Technical solution adopted in the utility model is: a kind of gear clearance cancellation element, it comprises transmission shaft, be arranged on the master gear on transmission shaft, be arranged on transmission shaft is close to master gear conjunction from gear, torsion spring, master gear and adopt same gear to be split to form through Linear cut from gear, described is provided with the first fixed hole from gear, described transmission shaft is near being provided with the second fixed hole from one end of gear, described one end is arranged in the first fixed hole, and the other end is arranged in the second fixed hole.
After adopting above structure, the utility model compared with prior art has the following advantages: torsion spring is arranged on transmission shaft and between gear, structure is simple, and only need to establish fixed hole at transmission shaft with from gear, easy for installation, cost is low.
As preferably, described master gear and be fixedly mounted on transmission shaft by flat key from gear, moves more stable, master gear and can not skidding between gear, and easy for installation, and cost is low.
As preferably, described is larger than the width of keyway on master gear from the width of keyway gear, and structure is simple, can realize master gear and from the relativity shift between gear, realize side set.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in the figure, the utility model provides a kind of gear clearance cancellation element, it comprises transmission shaft 1, be arranged on the master gear 2 on transmission shaft 1, be arranged on transmission shaft 1 is close to master gear 2 conjunction from gear 3, torsion spring 4, master gear 2 and adopt same gear to be split to form through Linear cut from gear 3, described is provided with the first fixed hole 5 from gear 3, described transmission shaft 1 is near being provided with the second fixed hole 6 from one end of gear 3, described torsion spring 4 one end is arranged in the first fixed hole 5, the other end is arranged in the second fixed hole 6, torsion spring 4 is arranged on transmission shaft 1 and between gear 3, structure is simple, only need to establish fixed hole at transmission shaft 1 with from gear 3, easy for installation, cost is low.
As preferably, described master gear 2 and be fixedly mounted on transmission shaft 1 by flat key 7 from gear 3, moves more stable, master gear 2 and can not skidding between gear 3, and easy for installation, and cost is low.
As preferably, described is larger than the second width of keyway B on master gear 2 from the first width of keyway b gear 3, and structure is simple, can realize master gear 2 and from the relativity shift between gear 3, realize side set.
Specifically, gear clearance cancellation element is used for eliminating the gap between gear specially, because after the gear operation time has been grown, gear has wearing and tearing, gap will be produced between gear, like this, abnormal sound will be produced between gear, gear-driven accuracy can reduce, by there being the torsion spring 4 of certain pretightening force to be connected between first fixed hole 5 with the second fixed hole 6, the elimination of the utility model gear clearance is exactly the pretightening force relying on torsion spring 4, rotate from gear 3 at transmission shaft 1, side set is produced with master gear 2, make to be close to engaging gear from gear 3 and master gear 2, thus elimination gear clearance, this device can at Spur Gear Driving and Helical gear Transmission, in running, master gear 2 be equivalent to a gear from gear 3, engage with engaging gear.
Be described with regard to the utility model preferred embodiment above, but can not be interpreted as it is limitations on claims.This practicality is carried out and is not only confined to above embodiment; its concrete structure allows to change; the number of such as gear can change; it can be two or more; but master gear with must alternately from gear, all various changes done in the protection domain of the utility model demand for independence are all in protection domain of the present utility model.
