Abstract
The utility model belongs to the field of the mechanical connection structure, and discloses a quick-disassembling elastic plug coupler, which comprises a drive shaft coupling half and a driven shaft coupling half, an opposite inner hole of both coupling halves is provided with a key slot which is connected with a corresponding shaft through a key, a plug is arranged inside a flange hole of the two coupling halves, the two coupling halves are connected with each other through a press plate, a bolt and a plug, and the inner wall on the end part of the opposite inner holes of the two coupling halves is provided with an expansion sleeve with the inner diameter being identical to that of the inner hole. The quick-disassembling elastic plug coupler can be manufactured and installed simply. The processing of the shaft and the hole with the expansion sleeve is free from requiring high-precision manufacturing tolerance as the interference fit and is also free from heating, cooling or pressurizing devices; and the adjustment is convenient, the two coupling halves can be conveniently adjusted to the required position on the shaft, good interchangeability can be realized, the coupling halves with large fit clearance can be joined together, the disassembling is convenient, the pieces to be connected can be seperated by unscrewing the bolt; and heavy load can be supported.
Description
Technical field
The utility model belongs to mechanical coupling structure field, relates in particular to a kind of fast assembling-disassembling elastic dowel pin shaft coupling.
Background technique
Coupling is mechanically to be used for mechanical part that two axles that rotate are linked together, and elastic dowel pin shaft coupling is wherein a kind of.But there is following shortcoming in the interference fit dismounting mode of existing elastic dowel pin shaft coupling: the axle and the hole of interference fit need the highi degree of accuracy worker poor, need heating, cooling and pressurized equipment during installation, dismounting inconvenience.
The model utility content
For overcoming the deficiencies in the prior art part, the purpose of this utility model is to provide a kind of fast assembling-disassembling elastic dowel pin shaft coupling.
For achieving the above object, the technological scheme taked of the utility model is as follows:
A kind of fast assembling-disassembling elastic dowel pin shaft coupling, comprise driving shaft half-coupling, driven shaft half-coupling, be provided with in the relative endoporus of two half-couplings and be used for the keyway that key connects corresponding axis, be provided with pin in the flange hole of two half-couplings, connect by pressing plate, bolt, pin between two half-couplings, its specialization is: two half-couplings relatively in be installed with the internal diameter expansion set suitable on the inwall of bore ends with diameter of bore.Thus, two half-couplings are finished coaxial connection transmitting torque by the expanding cover locking that has keyway.
Further, described expansion set by lock bolt be fixed on two half-couplings relatively on the inwall of bore ends.
The utlity model has following advantage:
1. make and install simply, the axle of expansion set and the processing in hole are installed unlike interference fit, require the highi degree of accuracy manufacturing tolerances;
2. the installation expansion set also need not heating, cooling or pressurized equipment, bolt moment of torsion in accordance with regulations need only be tightened to get final product;
3. easy to adjust, half-coupling can be adjusted to desired location easily on axle, good interchangeability is arranged, expansion set can couple together the half-coupling of big matching gap, and convenient disassembly during dismounting is unscrewed bolt, and connected piece is taken apart easily;
4. the utility model fast assembling-disassembling elastic dowel pin shaft coupling is the modified model of traditional elastic pin coupler, can bear heavy duty.
Description of drawings
Accompanying drawing is the longitudinal section of the utility model when being used for axle and spool being connected.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is done into a ground and introduce in detail, but protection domain of the present utility model is not limited thereto:
As shown in drawings, a kind of fast assembling-disassembling elastic dowel pin shaft coupling, comprise driving shaft half-coupling 1, driven shaft half-coupling 8, be provided with keyway 2 in the relative endoporus of two half-couplings 1,8 and be used for key connection corresponding axis, be provided with pin 6 in the flange hole of two half-couplings 1,8, connect by pressing plate 7, bolt 4, pin 6 between two half-couplings 1,8, two half-couplings 1,8 relatively in be installed with the internal diameter expansion set 3 suitable by lock bolt 5 on the inwall of bore ends with diameter of bore.
During installation: at first driving shaft half-coupling 1, driven shaft half-coupling 8 are assembled on driving shaft 9, the driven shaft 10 by keyway 2 usefulness flat keys respectively, expansion set 3 is installed then, tighten lock bolt 5 with fixing expansion set 3, the pin 6 of in the flange hole of two half-couplings 1,8, packing into again, at last pressing plate 7 is enclosed within two half-couplings 1,8 end separately respectively, tights a bolt 4.Thus, two half-couplings 1,8 are finished coaxial connection, transmitting torque by keyway 2, expansion set 3 lockings.
During dismounting, looser a bolt 4, remove separately two half-couplings 1,8 of pressing plate 7, the lock bolt 5 of unscrewing expansion set 3 can be finished the dismounting with two half-couplings 1,8.
Claims (2)
1. fast assembling-disassembling elastic dowel pin shaft coupling, comprise driving shaft half-coupling, driven shaft half-coupling, be provided with in the relative endoporus of two half-couplings and be used for the keyway that key connects corresponding axis, be provided with pin in the flange hole of two half-couplings, connect by pressing plate, bolt, pin between two half-couplings, it is characterized in that: two half-couplings relatively in be installed with the internal diameter expansion set suitable on the inwall of bore ends with diameter of bore.
