Abstract
The utility model provides an elastic coupling device of a double-key coupling one-way diaphragm, which ensures keys to be firmly connected in a key groove and to have higher transmission torque. The elastic coupling device of the double-key coupling one-way diaphragm comprises two coupling discs with flange plates and the diaphragm, two opposite flange plates and the diaphragm between two flange plates are connected by a bolt, two key grooves are arranged on shaft holes of the coupling discs, two threaded through holes are arranged on the coupling discs along radial direction, each threaded through hole is communicated with the bottom part of one key groove, and pressing studs are arranged in two threaded through holes.
Description
Technical field
The utility model relates to the unidirectional diaphragm elastic coupling flexible coupling of a kind of key joint.
Background technique
The unidirectional diaphragm elastic coupling flexible coupling of key joint comprises two connection dish, diaphragms that have flange plate, two relative flange plate and be arranged on two diaphragms between the flange plate and link to each other by bolt; Have a keyway on the axis hole of connection dish.During use, two connection dishes link to each other with driving shaft, driven shaft respectively by a key that is arranged in the keyway, thereby the moment of torsion of driving shaft is passed to driven shaft.Because the connection dish only links to each other with driving shaft or driven shaft by a key, the moment of torsion of transmission is less.And it is loosening easily and move axially to be arranged on key in the keyway.
The model utility content
The purpose of this utility model provides the unidirectional diaphragm elastic coupling flexible coupling of two key joints that key is connected firmly, driving torque is bigger in a kind of keyway.
This pair of unidirectional diaphragm elastic coupling flexible coupling of key joint comprises two connection dish, diaphragms that have flange plate, two relative flange plate and be arranged on two diaphragms between the flange plate and link to each other by bolt; Have two keyways on the axis hole of connection dish; Radially be provided with two tapped through holes on the connection dish, each tapped through hole communicates with the bottom of a keyway; In two tapped through holes, be provided with and compress double-screw bolt.
The utility model beneficial effect: during use, the connection dish links to each other with driving shaft, driven shaft respectively by two keys that are arranged in two keyways, thereby can transmit bigger moment of torsion.In addition, compress double-screw bolt, make the end compress double-screw bolt be pressed on the key, make key be pressed in and compress between double-screw bolt and the driving shaft (or driven shaft), prevent the becoming flexible of key in the keyway by tightening.

Embodiment
The unidirectional diaphragm elastic coupling flexible coupling of two key joints shown in Figure 1 comprises that two have 3, two relative flange plate 11 of connection dish 1, diaphragm of flange plate 11 and be arranged on two diaphragms 3 between the flange plate continuous by bolt 5; Have two keyways 6 (referring to Fig. 2,3) that are distributed on the axis hole on the axis hole of connection dish.Radially be provided with two tapped through holes 7 on the connection dish, tapped through hole communicates with the keyway bottom; In two tapped through holes, be provided with and compress double-screw bolt 8.
Claims (2)
1. two unidirectional diaphragm elastic coupling flexible coupling of key joint comprises two connection dish, diaphragms that have flange plate, two relative flange plate and be arranged on two diaphragms between the flange plate and link to each other by bolt; It is characterized in that: have two keyways on the axis hole of connection dish; Radially be provided with two tapped through holes on the connection dish, each tapped through hole communicates with the bottom of a keyway; In two tapped through holes, be provided with and compress double-screw bolt.
