Description
Technical field
The utility model is related to a kind of shaft coupling, specifically a kind of elastic dowel pin shaft coupling.
Background technology
Elastic dowel pin shaft coupling is the pin being made using some non-metallic elastic materials, is placed in two half a coupler flange holes
In, realize that two half a couplers couple by pin, the coupler structure is simple, easy to manufacture, assembly and disassembly are changed flexible member and compared
It is convenient, but be due to that structure design is single so that the relative displacement that shaft coupling transmission compensates two axles is smaller, in addition, pin and
Column pin hole fit clearance is larger, and the course of work easily produces larger noise, and structure design is unreasonable, uses Reliability comparotive
Difference, application is also greatly limited.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of offset greatly, and noise is small, uses good reliability, application
Extensive elastic dowel pin shaft coupling.
In order to solve the above-mentioned technical problem, elastic dowel pin shaft coupling of the present utility model, including left half shaft coupling and right half join
The confined planes of plate-like are provided with the middle part of axle and the outer shaft for being enclosed on left half shaft coupling and right half shaft coupling, outer shaft, outside
Cydariform pin retainer is respectively arranged between axle sleeve and left half shaft coupling and between outer shaft and right half shaft coupling, cydariform pin is protected
The surfaces externally and internally for holding frame is provided with resettlement groove, and the inner surface setting of outer shaft has the peace with cydariform pin retainer outer surface
The outside fix groove of groove cooperation is put, the outer surface of left half shaft coupling and right half shaft coupling is provided with and inner surface in cydariform pin retainer
The interior locating slot that coordinates of resettlement groove, between the cydariform pin retainer and outer shaft and cydariform pin retainer and left half
Outer cydariform pin and interior cydariform pin are mounted between shaft coupling and right half shaft coupling respectively, the left and right sides of outer shaft, which has, to be sealed on
Cover plate on outer shaft two side ends end face.
The resettlement groove is provided with the curved surfaces coordinated with cydariform pin with outside fix groove and interior locating slot.
The inner surface of the outer shaft towards cover plate direction tilts extension from top to bottom from the spacing of plate-like, and described left half joins
The outer surface of axle and right half shaft coupling is same towards cover plate direction to tilt extension, the cydariform pin from top to bottom from the spacing of plate-like
Retainer is same towards cover plate direction to tilt extension from top to bottom from the spacing of plate-like.
The outer cydariform pin and interior cydariform pin are nylon elastic pin.
After above-mentioned structure, due to setting because being located between overcoat and the shaft coupling of left and right half for setting has peace
Put the cydariform pin retainer of groove and the cydariform pin that is placed between overcoat and cydariform pin retainer and be placed in left and right
Cydariform pin between half shaft coupling and cydariform pin retainer, compensates very big thus, it is possible to two layers of cydariform pin by setting
Transmission axial dipole field, the cydariform pin retainer of setting has extraordinary holding effect so that the stability of work is good, disappears
Except noise, and its reasonable in design, it is greatly improved using reliability, application is also very wide, separately
Outside, its inclined structure design, further increases the stability of work and uses reliability.
Brief description of the drawings
Fig. 1 is the mounting structure schematic diagram of the utility model elastic dowel pin shaft coupling.
Embodiment
With reference to the accompanying drawings and detailed description, elastic dowel pin shaft coupling of the present utility model is made further specifically
