Abstract
The utility model discloses an elastic part for shaft couplings. For reducing stress concentration, the tooth shape root of the elastic part of a claw-shaped elastic shaft coupling is a recessed type cambered structure; the root basic angle of the trapezoidal groove of the elastic ring of an elastic ring column pin shaft coupling is a round angle; the elastic part is made from polyamine ester material. The elastic part for shaft couplings has high mechanical intensity, and favorable abrasion resisting performance and extrusion resisting performance; the utility model can eliminate the stress concentration of the root of the trapezoidal groove or tooth shape grooves of the elastic part.
Description
The utility model relates to the engineering part coupling, is a kind of elastic component that is used on pawl type elastic coupling flexible coupling, the elastic ring column pin shaft coupling.
The rubber parts of the pawl type elastic coupling flexible coupling of prior art or the elastic ring of elastic ring column pin shaft coupling, employing rubber is made, and mechanical strength is low, wear no resistance, and its profile of tooth root or dovetail groove root easily produce stress and concentrate, the wearing and tearing fracture phenomena is serious in the use, needs often to change.
Purpose of design of the present utility model is to overcome deficiency of the prior art, and a kind of wear-resisting property is good, mechanical strength is high, can eliminate the profile of tooth root of elastic component or the coupling elastic component that stress is concentrated, non-damageable new material is made of dovetail groove root and provide.
Purpose of design of the present utility model can reach by following measure:
The profile of tooth of coupling elastic component or trapezoidal root adopt and reduce the structure that stress is concentrated--and the profile of tooth root of the elastic component of pawl type elastic coupling flexible coupling is that the place, root base angle of dovetail groove of the elastic ring of concave type arcuate structure, elastic ring column pin shaft coupling is fillet, and its material is a polyamine fat.
Purpose of design of the present utility model can also reach by following measure:
The coupling elastic component is the elastic component of pawl type elastic coupling flexible coupling, and its profile of tooth root is the concave type arcuate structure.
The coupling elastic component is the elastic ring of elastic ring column pin shaft coupling, and place, dovetail groove root base angle is fillet.
Adopt at the bottom of the curve bath at the bottom of the dovetail groove of the elastic ring of above-mentioned elastic ring column pin shaft coupling.
The utility model compared with prior art has following advantage:
1. mechanical strength height, wear-resisting property is good, and anti-extrusion performance is good.
2. eliminating the profile of tooth root of elastic component or the stress of dovetail groove root concentrates.
The drawing of accompanying drawing is described as follows:
Fig. 1: the structural representation plan view of embodiment's one pawl formula elastic coupling flexible coupling elastic component
Fig. 2: the structural representation A-A sectional view of embodiment's one pawl formula elastic coupling flexible coupling elastic component
Fig. 3: the structural representation of embodiment's two elastic ring column pin shaft coupling elastic rings
Fig. 4: the structural representation of embodiment's three elastic ring column pin shaft coupling elastic rings
The utility model is described in further detail below in conjunction with drawings and Examples:
Embodiment one:
Fig. 1,2 shows the structure of the elastic component that has serrate slot of the utility model pawl formula elastic coupling flexible coupling.Its profile of tooth root is the concave type arcuate structure.The manufacturing of elastic component adopts polyamine fat material casting thermosetting to be shaped.
Embodiment two:
Fig. 3 shows the structure of the elastic ring that has dovetail groove of the utility model elastic ring column pin shaft coupling.The place, base angle of its dovetail groove root is fillet.Adopt polyamine fat material casting thermosetting to be shaped.
Embodiment three:
Fig. 4 shows the structure that the utility model elastic ring column pin shaft coupling has the elastic ring of dovetail groove.Except place, the base angle of its dovetail groove root for the fillet, also curved at the bottom of its dovetail groove, promptly at the bottom of the dovetail groove be curve bath at the bottom of.Adopt polyamine fat material casting thermosetting to be shaped.
