Abstract
The invention discloses a mechanical part connector capable of not relying on an elastic gasket. The mechanical part connector comprises a screw rod and a nut. The nut comprises a nut body. The screw rod comprises a screw rod section and a nut end arranged at the end of the screw rod section. A plurality of elastic protrusions are arranged on the end surface, close to the screw rod section, of the nut end and the end surface, close to the nut end, of the nut and can elastically deform in the screwing process of the screw rod. The free ends of the elastic protrusions incline towards the direction of unscrewing the mechanical part connector. The mechanical part connector provided by the invention has good anti-loosening capacity without being matched with the elastic gasket. The free ends of the elastic protrusions incline towards the direction of unscrewing the mechanical part connector, so that the deformation of the elastic protrusions is guided in the screwing process of the mechanical part connector. In this way, the elastic protrusions are easily forced to elastically deform, and the technical effect of conveniently screwing the mechanical part connector is realized.
Description
Technical field
The present invention relates to mechanical fastener technical field, particularly relate to a kind of machine components connector that does not rely on elastic washer.
Background technology
Bolt is a kind of machine components, is generally the cylindrical threaded securing member of adapted nut. Bolt is made up of head and screw rod (with externally threaded cylinder) two parts, when use, need coordinate with nut, and for being fastenedly connected two parts with through hole, this type of attachment claims bolt to connect. As nut is screwed off from bolt, can make again these two parts separately, be to belong to removably connect therefore bolt connects. Divide by the force way connecting: point common and have articulation hole to use. Divide by nose shape: there is turret head, round end, square spigot, countersunk head etc. Wherein turret head is the most frequently used.
At present, for bolted locking, comparatively general a kind of form is to adopt elastic washer. But in actual maintenance process or assembling process; particularly, in maintenance process, often can, because of maintainer's carelessness or not responsible, elastic washer be sheathed on bolt; cause tie point absent-mindedness under vibrations, occur seal failure or connect lax situation occurring.
Summary of the invention
For in above-mentioned prior art in actual maintenance process or assembling process; particularly in maintenance process; often can be because maintainer's carelessness or not responsible; elastic washer is not sheathed on bolt; cause tie point absent-mindedness under vibrations; there is seal failure or connect the problem that lax situation occurs, the invention provides a kind of machine components connector that does not rely on elastic washer.
A kind of machine components connector that does not rely on elastic washer provided by the invention solves problem by following technical essential: a kind of machine components connector that does not rely on elastic washer, comprise screw rod and nut, described nut comprises nut body, described bolt comprises spiro rod section and is arranged at the nut end of spiro rod section end, on the end face of described nut end near spiro rod section, be provided with multiple elastic bumps on the end face of nut body near nut end, described elastic bumps can produce strain in the process of bolt tightening; The setting that the free end of elastic bumps tilts towards the direction of absent-mindedness machine components connector.
In this structure, on the spiro rod section of setting, have screw thread, connect and be threaded with nut for bolt, with fastening interconnective connector, that rotates using upper cap nut end as operator's brake screw section turns parts. In this structure, by elastic bumps being set at nut end on the end face near spiro rod section one end, like this, in the process of bolt tightening, elastic bumps generation elastic deformation, the elastic force that above elastic deformation produces can be used as the prestressing force of screw retention, like this, this bolt, in the situation that not matching use cushion, also has good anti-loosening ability.
The nut body arranging is for being connected with screw flight, with fastening interconnective connection. In this structure, by elastic bumps being set on the end face in any one end of nut body, like this, in the process of tightening at nut, elastic bumps contacts with workpiece elastic deformation occurs, and the elastic force that above elastic deformation produces can be used as the locking prestressing force of nut body, like this, this bolt, in the situation that not matching use cushion, also has good anti-loosening ability.
The setting that adopts the free end of elastic bumps to tilt towards the direction of absent-mindedness machine components connector, can in the process that machine components connector is tightened, produce guide effect to the distortion of elastic bumps, like this, be easy to force elastic bumps strain, reach the technique effect of being convenient to tighten mechanical part connecting pieces.
Further technical scheme is:
For above prestressing force was upwards uniformly distributed in the week of bolt, the elastic bumps on two end faces is all uniform in the form of a ring with respect to the axis of spiro rod section.
As making above prestressing force upwards be uniformly distributed further technical scheme in the week of bolt, the number of the elastic bumps on two end faces is all greater than 3.
As a kind of connector form of being convenient to processing and manufacturing, the elastic bumps on described nut end, spiro rod section and nut end is the overall structure forming by casting; Elastic bumps on described nut body and nut body is the overall structure forming by casting.
The present invention has following beneficial effect:
In this structure, on the spiro rod section of setting, have screw thread, connect and be threaded with nut for bolt, with fastening interconnective connector, that rotates using upper cap nut end as operator's brake screw section turns parts. In this structure, by elastic bumps being set at nut end on the end face near spiro rod section one end, like this, in the process of bolt tightening, elastic bumps generation elastic deformation, the elastic force that above elastic deformation produces can be used as the prestressing force of screw retention, like this, this bolt, in the situation that not matching use cushion, also has good anti-loosening ability.
The nut body arranging is for being connected with screw flight, with fastening interconnective connection. In this structure, by elastic bumps being set on the end face in any one end of nut body, like this, in the process of tightening at nut, elastic bumps contacts with workpiece elastic deformation occurs, and the elastic force that above elastic deformation produces can be used as the locking prestressing force of nut body, like this, this bolt, in the situation that not matching use cushion, also has good anti-loosening ability.
The setting that adopts the free end of elastic bumps to tilt towards the direction of absent-mindedness machine components connector, can in the process that machine components connector is tightened, produce guide effect to the distortion of elastic bumps, like this, be easy to force elastic bumps strain, reach the technique effect of being convenient to tighten mechanical part connecting pieces.
