Description
Technical field
The present invention relates to the multi-thread compound new-type screw thread of tooth form of one kind.
Background technology
Thread connection and worm drive are worked using thread part, and thread connection has installs easy, dismounting side
Just, standardization level is high, interchangeability is strong, simple operation and other advantages, is most widely used removable connection；Worm drive are then one
Plant and become the characteristics of gyration is the type of belt drive for moving along a straight line, thread connection as very big axial direction can be produced when screw thread is tightened
Power, it can conveniently realize self-locking, and appearance and size is small；Thread connection and worm drive easily loosen under alternate load；Screw thread joins
The intensity for connecing mainly determines by the intensity of bolt, after bolted on connection is carried, load be by the screw thread facing of screw bolt and nut come
Transmission, because the rigidity of screw bolt and nut is different with deformation properties, so there is each circle ridge unbalance stress for screwing
Phenomenon, influences the intensity of bolt；Worm drive are that the screw pair constituted using screw rod and nut is required to realize being driven, main to use
Gyration is changed into linear motion, worm drive can be divided into slip screw, rolling screw and static pressure spiral by frictional property,
Typically always there is gap in slip screw, abrasion post gap is increased, and idle running will be produced when screw rod counter motion, high to required precision
Should take gap removing measure, cumbersome, rolling friction structure is complicated, and the screw rod of static pressure spiral is common trapezoidal thread
Screw rod, and in this kind of structure, nut structure is complicated, processing mounting and adjusting is more difficult, it is impossible to which self-locking is, it is necessary to a set of fueller；
The conventional tooth form of thread connection and screw-driven has three kinds, triangle, rectangle, trapezoidal.Every kind of tooth form has respective advantage and disadvantage,
Traditional screw thread either single line or multi-thread, is all to use a kind of tooth form, thus after loosening, abrasion occur in use
Repair the problem that difficult or transmission accuracy declines；And after thread connection is carried, load is by the screw thread facing of screw bolt and nut
Come what is transmitted, rigidity, deformation difference due to screw bolt and nut, so the load of each circle ridge for screwing is unevenly distributed
, in load bearing process, screw rod Tensile, pitch increase, nut is compressed, and pitch reduces, and both are to screw to be adjacent to all the time
, therefore the difference in change of this pitch compensates mainly by the deformation of each circle ridge, and use high nut, excessive increase rotation
Close effect of the number of turns to improving linking intensity little；In thread connection and worm drive, in alternate load effect, what screw thread linked closely
State just there occurs change, occur in that relaxed condition, influence the intensity and transmission progress of thread connection, in sum, it is necessary to
It is improved.
The content of the invention
Present invention solves the technical problem that：A kind of multi-thread compound new-type screw thread of tooth form is provided, it is outside by the axle in body
Set that tooth form that a plurality of helix formed is not all the same and equally distributed screw thread in circumferential wall, efficiently solve thread connection
There is lax phenomenon in use in part, and the linking intensity and transmission accuracy of thread connector are greatly improved, simple structure,
Without idle running phenomenon, thread connector bearing capacity is strong.
The technical solution adopted by the present invention：The multi-thread new-type screw thread of compound tooth form, with body, the axial direction of the body is cylindrical
The screw thread that a plurality of helix being equally spaced is formed, and the infull phase of form of thread that each helix is formed are machined with perisporium
Together, the counterpart that the helix of the body and body, tooth form are adapted realized after screwing body and counterpart linking intensity or
The raising of transmission accuracy.
Wherein, the tooth form species of the screw thread is triangle or rectangle or trapezoidal, the thread helix line number on the body
Amount >=2, tooth form species >=2 kind of the screw thread and staggeredly be equally spaced on body.
Present invention advantage compared with prior art：
1st, it is not all the same and uniform by setting on the axial outer circle wall of body the tooth form that a plurality of helix formed
The screw thread of distribution, efficiently solves thread connector and occurs lax phenomenon in use, and the connection of thread connector is strong
Degree and transmission accuracy are greatly improved；
2nd, the bonding strength and transmission accuracy of thread connector can be according to the demands of real work situation, by selecting spiral
The quantity of tooth form and helix processes screw thread on body outer circle wall, and selection species is more, the linking intensity and biography of body
Dynamic accuracy selection scope is big；
3rd, simple structure, without idle running phenomenon, thread connector bearing capacity is strong.
