Abstract
The invention belongs to the field of mechanical connection and relates to a two-parallel-face installation structure capable of eliminating structure pre-tightening force. The two-parallel-face installation structure capable of eliminating structure pre-tightening force comprises two parallel installation faces and a part to be installed, wherein the part to be installed is arranged between the two parallel installation faces; bolt installation holes are formed in the two parallel installation faces; a bolt installation hole is formed in one end face of the part to be installed; a bush installation hole is formed in the other end face of the part to be installed; the end face, provided with the bolt installation hole, of the part to be installed is attached to one installation face; a bolt B sequentially penetrates through a gasket C, the corresponding end face of the part to be installed, the corresponding installation face, a gasket D and a nut B to achieve connection of one side; a bolt A sequentially penetrates through a gasket A, a bush, the end face, provided with the bush installation hole, of the part to be installed, the other installation face, a gasket B and a nut A to achieve connection of the other side. The situation that when equipment is connected with two parallel faces and the width of the equipment and the distance between the two installation faces are in clearance fit, the equipment or the installation faces plastically or elastically deform due to pre-tightening force is avoided, and the fatigue life of the equipment or a previous-stage mechanism is prolonged.
Description
Technical field
This common invention belongs to mechanical connection field, relates to a kind of parallel two sides mounting structure eliminating structure pretightening force.
Background technique
When a certain equipment needs to connect with parallel two sides bolt, and the distance of the width of equipment and two attachment faces is Spielpassung, and when tightening connecting bolt, equipment or attachment face can produce plasticity or resiliently deformable because of pretightening force.
Common invention content
The object of this common invention is:
A kind of parallel two sides mounting structure eliminating structure pretightening force is provided, by adding the method for lining in one-sided bolt joint, avoid equipment to connect with parallel two sides and the distance of the width of equipment and two attachment faces is Spielpassung time, equipment or attachment face produce plasticity or resiliently deformable because of pretightening force, increase the fatigue life of equipment or upper level mechanism.
The technical solution of this common invention is:
A kind of parallel two sides mounting structure eliminating structure pretightening force, this mounting structure comprises: two parallel attachment faces and to be installed, assembling set is placed between two parallel attachment faces, two parallel attachment faces have bolt mounting holes, a to be installed end face has bolt mounting holes, another to be installed end face has bushing mounting holes, to be installed end face and one of them attachment face of opening bolt mounting holes are adjacent to, bolt B is successively through packing ring C, to be installed end face, attachment face, packing ring D, nut B, realize side to connect, bolt A is successively through packing ring A, lining, open to be installed end face of bushing mounting holes, another attachment face, packing ring B, nut A, realize other side to connect.
The length of lining ensures that to be installed the end face opening bushing mounting holes does not contact with packing ring A with attachment face.
Lining and bolt A internal surface are Spielpassung, and lining and bushing mounting holes are Spielpassung or transition fit.
The advantage that this common invention has and beneficial effect:
This common invention avoid equipment connect with parallel two sides and the distance of the width of equipment and two attachment faces is Spielpassung time, equipment or attachment face produce plasticity or resiliently deformable because of pretightening force, increase the fatigue life of equipment or upper level mechanism.
Accompanying drawing explanation
Fig. 1 is the structural representation of this common invention;
Fig. 2 is the structural representation of to be installed of this common invention.
Wherein, the parallel attachment face of 1-two, to be installed of 2-, 3-lining, 4-bolt A, 5-packing ring A, 6-packing ring B, 7-nut A, 8-bolt B, 9-packing ring C, 10-packing ring D, 11-nut B
Embodiment
Below in conjunction with accompanying drawing, this common invention is elaborated.A kind of parallel two sides mounting structure eliminating structure pretightening force, this mounting structure comprises: two parallel attachment faces and to be installed, assembling set is placed between two parallel attachment faces, two parallel attachment faces have bolt mounting holes, a to be installed end face has bolt mounting holes, another to be installed end face has bushing mounting holes, to be installed end face and one of them attachment face of opening bolt mounting holes are adjacent to, bolt B is successively through packing ring C, to be installed end face, attachment face, packing ring D, nut B, realize side to connect, bolt A is successively through packing ring A, lining, open to be installed end face of bushing mounting holes, another attachment face, packing ring B, nut A, realize other side to connect.
The length of lining ensures that to be installed the end face opening bushing mounting holes does not contact with packing ring A with attachment face.
Lining and bolt A internal surface are Spielpassung, and lining and bushing mounting holes are Spielpassung or transition fit.
The mounting hole diameter of two parallel attachment faces is the same, to be installed to be adjacent to the mounting hole diameter of the mounting hole 2-1 attachment face parallel with two of side consistent with two parallel attachment faces, the mounting hole 2-2 diameter of to be installed other side is consistent with Outer Diameter of lining, bushing inner diameter is consistent with the mounting hole diameter of two parallel attachment faces, the length of lining ensures that to be installed has the both sides, one side of mounting hole 2-2 not contact with lining with scaffold, thus avoids scaffold and to be installed to produce plasticity or resiliently deformable.
Claims (3)
1. can eliminate the parallel two sides mounting structure of structure pretightening force for one kind, it is characterized in that, this mounting structure comprises: two parallel attachment faces and to be installed, assembling set is placed between two parallel attachment faces, two parallel attachment faces have bolt mounting holes, a to be installed end face has bolt mounting holes, another to be installed end face has bushing mounting holes, to be installed end face and one of them attachment face of opening bolt mounting holes are adjacent to, bolt B is successively through packing ring, to be installed end face, attachment face, packing ring, nut, realize side to connect, bolt A is successively through packing ring, lining, open to be installed end face of bushing mounting holes, another attachment face, packing ring, nut, realize other side to connect.
