The utility model discloses a with being equipped with thread and screw on the nut body, spiral shell tooth position in the outer edge of screw, the screw is equipped with the chamfer with nut body both sides terminal surface crossing department, is equipped with round tooth and root of the tooth on the thread, and the circle tooth distributes with the root of the tooth in turn, still is equipped with the crest on the circle tooth, and the crest is located round root of thread portion center, and the thread revolves to for the levogyration, can make levogyration circle tooth nut and levogyration tooth strip well cooperate the transmission to the dismouting is maintained conveniently, and the use of a plurality of round tooth nuts can be spacing fast simultaneously, improves work efficiency.
Description
[technical field]
The utility model relates to the technical field of nut, particularly the technical field of left-handed round tooth nut.
[background technique]
Various equipment is applied to different industries now, some important equipment, also different Special use performances is had, just need to use different special entities and component to reach specific requirement, and the apparatus field of transmission is needed at lathe and some, just need to use gear rack, gear rack at transmission field also referred to as screw mandrel, gear rack is as the major part on transmission device, the requirement of its use and quality thereof is all very high, when some are special, gear rack not only will bear the driving torque in substantially horizontal, also to have the gravity requirement of bearing on part vertical direction, the normal work of gear rack is indispensable for the normal operation of whole transmission device, and ballscrew nut fitting, because its ensuring smooth transmission, there is reversibility, be widely used in the transmission fields such as lathe.The gear rack majority that tradition uses is all clockwise drive, need the left-handed gear rack used in some cases, left-handed gear rack coordinates with ball parafacies, because ball and gear rack are worn and torn for a long time, needs irregular replacing ball, dismounting is not very convenient, and do not seeing other effective replacing method on the market, need, when gear rack upper limit, also can only rely on the requirement that some supplementary equipment and instrument reach fixing simultaneously, add numerous and diverse degree of work, reduce working efficiency.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, propose a kind of left-handed round tooth nut, left-handed round tooth nut and the good fit transmission of left-handed gear rack can be allowed to, and dismounting is easy to maintenance, the use of multiple round tooth nut can be spacing fast simultaneously, increases work efficiency.
For achieving the above object, the utility model proposes a kind of left-handed round tooth nut, comprise nut body, screw and thread, described nut body is provided with thread and screw, thread is positioned at screw outer, described screw and nut body both sides face intersection are provided with chamfering, and described thread is provided with round tooth and root of the tooth, and circle tooth and root of the tooth are alternately distributed, described round tooth radius of arc is 4.2mm, described round tooth is also provided with crest, and crest is positioned at Yuan Ya bottom centre, and described thread rotation direction is left-handed.
As preferably, end face outer place, described nut body both sides is also provided with fillet, and described fillet radius is 5mm.
As preferably, described chamfering is 45 degree of chamferings, and chamfering length is 0.5mm.
As preferably, described thread tooth distance degree equals circle tooth arc diameter, and tooth distance is 8.4mm.
As preferably, described root of the tooth width is 2.2mm.
The beneficial effects of the utility model: the utility model is by being provided with thread and screw by nut body, thread is positioned at screw outer, screw and nut body both sides face intersection are provided with chamfering, thread is provided with round tooth and root of the tooth, circle tooth and root of the tooth are alternately distributed, circle tooth is also provided with crest, crest is positioned at Yuan Ya bottom centre, thread rotation direction is left-handed, left-handed round tooth nut and the good fit transmission of left-handed gear rack can be allowed to, and dismounting is easy to maintenance, the use of multiple round tooth nut can be spacing fast simultaneously, increases work efficiency.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
