Abstract
The invention belongs to drive mechanism design fields, and in particular to a kind of gear-driven assembly.Current gear-driven assembly is repeatedly assembled and disassembled its positioning accuracy and reliability and can be reduced.Gear-driven assembly of the invention, including RVDT axis and gear, the gear have the sleeve of one in end face, have oval locating slot on the bar portion surface of the RVDT axis；The sleeve is " Ω " type structure, two claws of its opening and the end face of gear have gap, opposite region is integrated with gear with being open, described two claws have opposite threaded hole, it is open and clamps when the screw is threadedly coupled with two pawls, and the bar portion of screw is caught in the oval locating slot.Processing technology and installing/dismounting method simplify, and can be improved positioning accuracy and reliability；Reduce processing request.
Description
Technical field
The invention belongs to drive mechanism design fields, and in particular to a kind of gear-driven assembly.
Background technique
Gear 2 and positioning pin 3 of a kind of current gear-driven assembly referring to Fig. 1-3, including RVDT axis 1, with sleeve.
There is a pin hole 1a on RVDT axis, there is a pin hole 2a on the sleeve of gear 2, gear 2 is covered on RVDT axis 1 by hub bore, will be positioned
Pin 3 passes through pin hole 1a and pin hole 2a and fixation.Gear 2 is circumferential and radial all realize installs positioning.Positioning pin 3 and pin hole were
It is full of cooperation, repeatedly being assembled and disassembled its positioning accuracy and reliability can reduce.RVDT axis and gear 2 pass through Combined machining and obtain pin hole 1a
And 2a, so that it increases process with high concentricity.Simultaneously all to pin hole and positioning pin surface roughness and fit tolerance
It there are certain requirements, processing request is high.
Summary of the invention
The purpose of the present invention is: propose a kind of improved gear-driven assembly；Meet long-term being dismounted for multiple times to use and guarantee
Precision.
The technical scheme is that a kind of gear-driven assembly, including RVDT axis and gear, the gear have in end face
The sleeve of one has oval locating slot on the bar portion surface of the RVDT axis；The sleeve is " Ω " type structure, opening
Two claws at place and the end face of gear have gap, and opposite region is integrated with gear with being open, described two claw tools
There is opposite threaded hole, is open and clamps when the screw is threadedly coupled with two pawls, and the bar portion of screw is caught in the ellipse
Locating slot.
The width of the ellipse locating slot is identical as the bar diameter of screw.
Described two claws have opposite surface.
Region of the sleeve in conjunction with gear accounts for the 1/3~1/2 of the gross area.
The invention has the advantages that processing technology and installing/dismounting method simplify using gear-driven assembly of the invention, and
It can be improved positioning accuracy and reliability；Reduce processing request.

Specific embodiment
A kind of gear-driven assembly referring to fig. 4, including RVDT axis 1, gear 2 and screw 3, on the bar portion surface of RVDT axis 1
With oval locating slot 6, there is the sleeve 4 of one in the end face of gear 2, which is " Ω " type structure, opening
The end face of two claws 5 and gear 2 has gap, and opposite region is integrated with gear 2 with being open.Described two claws 5 have
There is opposite threaded hole.2 sets of gear on RVDT axis 1, are open when the screw 3 is threadedly coupled from side with two claws 5 and press from both sides
Tightly, the bar portion of screw 3 is caught in the oval locating slot 6.The width of the ellipse locating slot 6 is identical as 3 bar diameter of screw.Tooth
Wheel 2 has all obtained accurate installation positioning in axial and circumferential.
