The utility model discloses a with being equipped with cusp and tooth arc on the tooth strip, the cusp distributes with the tooth arc in turn, and tooth strip tip is equipped with the chamfer, and tooth strip terminal surface is equipped with the enhancement layer, still is equipped with on the enhancement layer and beats the mark platform, beats the mark platform and lies in center on the enhancement layer, can make levogyration tooth strip satisfy the operation requirement with beating mark department occasionally, beat the timestamp in addition and does not destroy tooth strip surface texture, the quality and the life of improvement tooth strip.
Description
[technical field]
The utility model relates to the technical field of gear rack, particularly the technical field of left-handed gear rack.
[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 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.Particularly on ballscrew nut fitting, because its ensuring smooth transmission, have reversibility, it is convenient to safeguard, is 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, and due to its special usage requirement, often easy stressed generation deformation, or because some special circumstances crack, and mark easily producing damage to gear rack surface when dispatching from the factory, easily using in the future and cracking, reducing the working life of gear rack.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of left-handed gear rack, has mark place, and do not destroy gear rack surface structure during mark while left-handed gear rack can be made to meet usage requirement, improves quality and the working life of gear rack.
For achieving the above object, the utility model proposes a kind of left-handed gear rack, comprise gear rack, cusp and tooth arc, described gear rack is provided with cusp and tooth arc, and cusp and tooth arc are alternately distributed, and described gear rack end is provided with chamfering, described gear rack end face is provided with reinforced layer, reinforced layer is also provided with mark platform, and mark platform is positioned at central position on reinforced layer, and described tooth arc radius of arc is 4.2mm.
As preferably, the cusp in described gear rack and tooth arc are alternately distributed the tooth line forming gear rack, and gear rack upper tooth line tooth is apart from being 8.4mm.
As preferably, described chamfer angle is 45 degree, and chamfering length is 0.5mm.
As preferably, the cusp in described gear rack and tooth hook are to being all left-handed.
The beneficial effects of the utility model: the utility model is by being provided with cusp and tooth arc by gear rack, cusp and tooth arc are alternately distributed, gear rack end is provided with chamfering, gear rack end face is provided with reinforced layer, reinforced layer is also provided with mark platform, and mark platform is positioned at central position on reinforced layer, has mark place while left-handed gear rack can be made to meet usage requirement, and do not destroy gear rack surface structure during mark, improve quality and the working life of gear rack.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
