Abstract
The utility model relates to a pear-shaped shaft end baffle plate. The pear-shaped shaft end baffle plate comprises a baffle plate body, wherein a first hole and a second hole are formed in the baffle plate body; a first groove and a second groove which can be used for communicating the first hole and the second hole with the outside are respectively formed in the end part in the length direction of the baffle plate body; the width of the first groove is smaller than the diameter of the first hole; the width of the second groove is smaller than the diameter of the second hole. According to the pear-shaped shaft end baffle plate, the first groove and the second groove which can be used for communicating the first hole and the second hole with the outside are respectively formed in the end part in the length direction of the baffle plate body, the width of the first groove is smaller than the diameter of the first hole, and the width of the second groove is smaller than the diameter of the second hole, and moreover, mobile reserve amount is provided for the pear-shaped shaft end baffle plate, and when the shaft bears heavy load, the pear-shaped shaft end baffle plate moves slightly, so that a fastening bolt can meet the shearing strength, and therefore, the fastening bolt is prevented from being sheared off, the locking of the shaft is unlikely to lose efficacy, and a locking effect is improved.
Description
Technical field
The utility model relates to a kind of baffle plate, relates in particular to a kind of pyriform axle end baffle plate.
Background technique
In mechanical engineering, there are a lot of axial workpieces and parts to carry out hinged, axle can be sheared and torsional load.Therefore, must to axle move axially and rotation limits, to prevent that axial workpiece from departing from that parts have an accident and dangerous.To the moving axially and rotate restriction and can adopt axle end baffle plate of axle, and pyriform axle end baffle plate is a kind of in the axle end baffle plate extensively adopting at present.The structure of the pyriform axle end baffle plate of prior art as shown in Figure 1, comprise baffle body 1, in described baffle body 1, have the first hole 2 and the second hole 3, the second hole 3 coordinates with axle, the first hole 2 use clamping bolts are fixed whole axle, and this structure is the moving axially and rotate of restrictive axes effectively.But the pyriform axle end baffle plate of this structure exists defect, the load of bearing when axle is too large, and clamping bolt be can not meet shear strength time, and clamping bolt can be cut off, and causes the locking of axle to be lost efficacy.
Model utility content
The utility model object is in order to overcome the deficiencies in the prior art, to provide a kind of locking effect of axle that makes to be difficult for the pyriform axle end baffle plate losing efficacy.
For achieving the above object, the technical solution adopted in the utility model is: a kind of pyriform axle end baffle plate, comprise baffle body, in described baffle body, have the first hole and the second hole, the end of described baffle body length direction has the first groove and the second groove that makes the first hole and the second hole and exterior; The width of described the first groove is less than the diameter in the first hole; The width of described the second groove is less than the diameter in the second hole.
Preferably, the width of described the second groove is 1/5th of the second bore dia.
Preferably, the width of described the first groove is 1/3rd of the first bore dia.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Pyriform axle end baffle plate of the present utility model, because the end of baffle body length direction has the first groove and the second groove that makes the first hole and the second hole and exterior, and the width of the first groove is less than the diameter in the first hole, the width of the second groove is less than the diameter in the second hole, give pyriform axle end baffle plate and move pre-allowance, the load of bearing when axle is too large, can there is tiny movement in pyriform axle end baffle plate, make clamping bolt can meet shear strength, avoided clamping bolt to be cut off, make the locking of axle be difficult for losing efficacy, improved locking effect.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
The structural representation of the pyriform axle end baffle plate that accompanying drawing 1 is prior art;
Accompanying drawing 2 is the structural representation of pyriform axle end baffle plate of the present utility model;
Wherein: 1, baffle body; 2, the first hole; 3, the second hole; 4, the first groove; 5, the second groove.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Described in the utility model a kind of pyriform axle end baffle plate as shown in Figure 2, comprise baffle body 1, in described baffle body 1, have the first hole 2 and the second hole 3, the end of described baffle body 1 length direction has the first groove 4 and the second groove 5 that makes the first hole 2 and the second hole 3 and exterior; The width of described the first groove 4 is less than the diameter in the first hole 2; The width of described the second groove 5 is less than the diameter in the second hole 3; The width of described the second groove 5 is 1/5th of the second hole 3 diameters; The width of described the first groove 4 is 1/3rd of the first hole 2 diameters.
Pyriform axle end baffle plate of the present utility model, because the end of baffle body length direction has the first groove and the second groove that makes the first hole and the second hole and exterior, and the width of the first groove is less than the diameter in the first hole, the width of the second groove is less than the diameter in the second hole, give pyriform axle end baffle plate and move pre-allowance, the load of bearing when axle is too large, can there is tiny movement in pyriform axle end baffle plate, make clamping bolt can meet shear strength, avoided clamping bolt to be cut off, make the locking of axle be difficult for losing efficacy, improved locking effect.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, within all dropping on the utility model rights protection scope.
Claims (3)
1. an axle end baffle plate, comprises baffle body, has the first hole and the second hole in described baffle body, it is characterized in that: the end of described baffle body length direction has the first groove and the second groove that makes the first hole and the second hole and exterior; The width of described the first groove is less than the diameter in the first hole; The width of described the second groove is less than the diameter in the second hole.
2. axle end baffle plate according to claim 1, is characterized in that: the width of described the second groove is 1/5th of the second bore dia.
