Description

A kind of split type three even take turns
Technical field
The present invention relates to mechanical transmission component field, a kind of split type three even take turns.
Background technology
Three in lathe headstock connect the component that wheel is independent one, coaxially divide row three waney teeth, three The round platform that is formed by undergauge between tooth, boss interval, endoporus have the axial rectangle keyway of decile.This gear overall processing difficulty Greatly, low precision, low production efficiency.
Invention content
It is an object of the present invention to provide a kind of split type three even to take turns, and solves existing independent body three and even takes turns all processing problems.
This split type the three of the present invention even take turns, and shape and independent body three are even taken turns identical, and split type three even there is decile in hole in wheel Axial rectangle keyway, it is characterised in that the independent body three of similar shape is even taken turns and splits into three gear parts, by the outer of complete gear wheel Edge diameter divides into middle gear, gear wheel, pinion gear;Connection structure is an end slot of middle gear along the groove for being inserted into gear wheel It is entrenched togather, gear wheel other end protrusion is embedded in the axial notch of pinion gear, and edge coincide, and elastic spring is used in combination to be stuck in small tooth Arc groove and the banding in the arc groove of gear wheel protrusion for taking turns circular arc protrusion outer wall are integral.
One three even wheel is decomposed into three components by the present invention, changes the shape of each junction, reconnection is integrated.It uses The endoporus that Shi Yinsan even takes turns will install splined shaft, therefore its intensity is unaffected.Split type three company wheel construction is simple, is set to processing It is low for requiring, while facilitating processing, and improve machining accuracy, processing cost is reduced instead.Based on this innovation mode, The different gear shapes combination that transmission needs can be met, it is integral to split processing reconnection, it is not necessary to special equipment is provided thus, Three are improved even to take turns the processing efficiency of like parts, reduce cost.

Specific implementation mode
Below in conjunction with the accompanying drawings and example illustrates the structure of the split type three-speed gear of the present invention
This split type three even take turns, and shape and integral type three are even taken turns identical, see Fig. 1, and split type three even there is decile in hole in wheel Axial rectangle keyway, it is characterised in that the independent body three of similar shape is even taken turns and splits into three gear parts, by the outer of complete gear wheel Edge diameter divides into middle gear 1, gear wheel 2, pinion gear 4;Connection structure is an end slot of middle gear 1 along insertion gear wheel 2 It in groove and rotating, two keyways is made to be connected to, 2 other end protrusion of gear wheel is embedded in the axial notch of pinion gear 4, and two keyways are connected to, It is used in combination elastic spring 3 to be stuck in the arc groove of 4 circular arc protrusion outer wall of pinion gear with banding in the arc groove of 2 protrusion of gear wheel at one Body.
See that 1 shape of middle gear is in Fig. 2 a, 2b:1 one end of middle gear is with teeth, the radial most of opposite contracting of other end outer circle Diameter retains the round platform formed with the undergauge residual altitude of internal diameter one, and round platform outer periphery has symmetrical two circular arcs convex It rises.
Fig. 3 a~3c see the shape of gear wheel 2:The maximum outer circle of gear wheel 2 is teeth portion, and there are undergauge platform, undergauge in teeth portion one end Size is more than that tooth is high, the circular arc that opposite axial arc notch is formed on undergauge platform, only retains two radial symmetrics on undergauge platform Protrusion, and circular arc protrusion outer wall has arc groove;The teeth portion other side is central diameter, and central diameter diameter is more than undergauge platform diameter, axial length More than the height of tooth;The central diameter other side is land, and land diameter is less than root portion diameter, and land outer end is in the outside half of endoporus Radial component is axial notch, and axial notch radially differs, and has at two radial strut lack and is longer than remaining position and and land Interior adjacent another axial notch connection, the short radial strut in remaining position of land outer end lack the adjacent another axial notch structure in land The long radial strut of the scarce annular groove of at the two of remaining position radial strut of growing up, gear wheel 2 lacks and 1 radial symmetric of middle gear Circular arc protrusion is coincide.
From the shape of pinion gear 4 in terms of Fig. 4 a, 4b:Maximum outer circle side is teeth portion, and at one end, teeth portion is another for 4 teeth portion of pinion gear Side is round platform, and round platform diameter is smaller than root diameter, and round platform end has opposite arc axial direction notch, axial notch height to be less than residue Frustum cone height, in two circular arc protrusions that axial notch is formed, the outer wall in height stage casing has arc groove.
As shown in Fig. 2, the maximum outer circle of gear 1 is gear tooth, side outer circle is two symmetrical projection portions, protrusion Partial outside is arc-shaped, and hole is rectangle keyway in gear, and gear both sides are plane
As shown in figure 3, the maximum outer circle of gear 2 is gear tooth, gear side is the internal circular groove with side edge, Wherein side is along being above two symmetrical recesses, and recess inboard is arc-shaped, and the other side is two symmetrical lug bosses Point, it is arc-shaped outside projection portion simultaneous with circular groove, hole is rectangle keyway in gear, and gear both sides are plane
As shown in figure 4, the maximum outer circle of gear 4 is gear tooth, gear side is two recesses, in recess Side is plane, there is circular groove in the outer circle of recess side, and hole is rectangle keyway in gear, and gear both sides are flat Face.
Gear 1 is linked together by the projection portion and the groove in 2 left side of gear on right side, and gear 2 passes through the convex of right side The recess for playing part and 4 left side of gear links together and is stuck in outside gear 2 and gear 4 with axle elastic spring 3 In circular groove.So that gear is become split type from monoblock type in this way, improve processing efficiency, reduces manufacturing cost.
