Abstract
The utility model discloses a straight gear. According to the technical scheme, one end of a gear body is provided with an annular protrusion which is concentrically arranged with a center shaft hole. The side face of the annular protrusion is provided with an elastic semicircular protrusion, and the axis direction of the elastic semicircular protrusion is parallel to the axis direction of the center shaft hole. The other end of the gear body is provided with an annular groove for the annular protrusion to slide in, and the side wall of the annular groove is provided with a block inlet groove for the elastic semicircular protrusion to slide in and is provided with a clamping groove which is matched with the elastic semicircular protrusion. When gears are placed or moved, the annular protrusion is placed into the annular groove, the gears are rotated, then the elastic semicircular protrusion is compressed, and when the gears are rotated to the position of the clamping groove, the elastic semicircular protrusion restores from deformation, so that two gears are clamped together and the stability effect is significant.
Description
Technical field
The utility model relates to a kind of technical field of mechanical transmission component, and more particularly, it relates to a kind of spur gear.
Background technique
Gear is one of important driving mechanism, and it has, and transmitted power scope is large, transmission efficiency is high, can realize motion between any diaxon and the feature of power.
Gear is when carrying, all that it is stacked and carried one by one, fixing owing to not realizing between them, in handling process, easily occur misplacing each other even dropping, so not only increase the difficulty of carrying gear, and caused the teeth of gear to occur damaging because dropping, caused unnecessary loss.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of spur gear of convenient carrying.
For achieving the above object, the utility model provides following technological scheme: a kind of spur gear, comprise gear body, the outer peripheral surface of described gear body is provided with some teeth that are uniformly distributed, described gear body is provided with central shaft hole, described gear body one end is provided with the annular protrusion with the concentric setting of central shaft hole, the side of described annular protrusion is provided with elasticity semi-circular projection, the described axial direction of elasticity semi-circular projection and the axial direction of central shaft hole are parallel, the other end of described gear body is provided with the annular groove slipping into for annular protrusion, the sidewall of described annular groove be provided with for elasticity semi-circular projection, slip into enter piece groove, the sidewall of described annular groove is provided with the draw-in groove suitable with elasticity semi-circular projection.
By adopting technique scheme, when putting or carry gear, elasticity semi-circular projection on a gear is aimed at and entered piece groove on another gear, so just annular protrusion can be snapped in annular groove, then rotate one of them gear, in the process of rotating at gear, elasticity semi-circular projection can be compressed, when elasticity semi-circular projection moves to draw-in groove position, elasticity semi-circular projection can be recovered original state, thereby realize two gears are stuck in to one, stabilizing effect is remarkable, projection is semicircle shape, make when installation and disengage gears convenient, projection easily skids off from draw-in groove, time saving and energy saving.
The utility model is further set to: the described radial cross section that enters piece groove is semicircle shape.
By adopting technique scheme, in transmitting gear, make elasticity semi-circular projection can be good at distortion, save strength greatly.
The utility model is further set to: described elasticity semi-circular projection has 2 and be positioned at the both sides of annular protrusion.
By adopting technique scheme, the both sides of gear are distributed with elasticity semi-circular projection, can be good at two gears to link together.
The utility model is further set to: the degree of depth of described annular groove is 1/3rd of gear body thickness.
By adopting technique scheme, the degree of depth of annular groove is gear body thickness 1/3rd, and this is not affecting the intensity of gear body, and appropriate depth facilitates clamping.
Accompanying drawing explanation
Fig. 1 is the utility model spur gear embodiment's structural drawing;
Fig. 2 is the utility model spur gear embodiment's axonometric drawing;
Fig. 3 is the utility model spur gear embodiment's structural representation.
Reference character: 1, teeth; 2, gear body; 3, annular protrusion; 4, elasticity semi-circular projection; 5, central shaft hole; 6, enter piece groove; 7, draw-in groove; 8, annular groove.
Embodiment
Referring to figs. 1 through Fig. 3, the utility model spur gear embodiment is described further.
A kind of spur gear, comprise gear body 2, the outer peripheral surface of described gear body 2 is provided with some teeth 1 that are uniformly distributed, described gear body 2 is provided with central shaft hole 5, described gear body 2 one end are provided with the annular protrusion 3 with the concentric setting of central shaft hole 5, the side of described annular protrusion 3 is provided with elasticity semi-circular projection 4, described elasticity semi-circular projection 4 has 2 and be positioned at the both sides of annular protrusion 3, the axial direction of described elasticity semi-circular projection 4 is parallel with the axial direction of central shaft hole 5, the other end of described gear body 2 is provided with the annular groove 8 slipping into for annular protrusion 3, the degree of depth of described annular groove 8 is 1/3rd of gear body 2 thickness, the sidewall of described annular groove 8 be provided with for elasticity semi-circular projection 4, slip into enter piece groove 6, the described radial cross section that enters piece groove 6 is semicircle shape, the sidewall of described annular groove 8 is provided with the draw-in groove 7 suitable with elasticity semi-circular projection 4.
When putting or carry gear, elasticity semi-circular projection on a gear 4 is aimed at and entered piece groove 6 on another gears, so just annular protrusion 3 can be snapped in annular groove 8, then rotate one of them gear, in the process of rotating at gear, elasticity semi-circular projection 4 can be compressed, and be circular-arc owing to entering the radial cross section of piece groove 6, more laborsaving in the process of transmitting gear, when moving to draw-in groove 7 positions, elasticity semi-circular projection 4 makes, elasticity semi-circular projection 4 can be recovered original state, thereby realize two gears are stuck in to one, and two elasticity semi-circular projection 4 lay respectively at the both sides of annular protrusion 3, stabilizing effect is remarkable, projection is semicircle shape, make when installation and disengage gears convenient, projection easily skids off from draw-in groove 7, time saving and energy saving, and the degree of depth of annular groove 8 is gear body 2 thickness 1/3rd, this is not affecting the intensity of gear body 2, and appropriate depth facilitates clamping.
