Abstract

The invention discloses a split type three-connection wheel with the shape same as an integral three-connection wheel. The split type three-connection wheel has a same shape as the integral three-connection wheel, and equally divided axial rectangular key grooves are formed in inner holes of gears respectively. The split type three-connection wheel is characterized in that individual gears with the same shape are split into three gear parts which are distinguished as a middle gear, a big gear and a small gear according to the outer edge diameter of an integral gear; and the connection structure is that an end groove of the middle gear is inserted into a groove of the big gear and is combined with the groove of the big gear in an embedding manner, a salient at the other end of the big gear is embedded into a recess of a circle center of the small gear to be combined with the small gear together, and a steel wire retaining ring is locked in an arch-shaped groove formed in the arch-shaped protruded outer wall of the small gear and an arch-shaped groove of the salient of the big gear so as to be hooked to form a whole body. The design is low in requirements for processing equipment and convenient to process and lowers the processing cost when improving the processing accuracy.

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
In lathe headstock three connect the part that wheel is independent one, coaxially point three waney teeth of row, three Round platform, the boss interval formed by undergauge between tooth, endoporus has the axial rectangle keyway of decile.This gear overall processing difficulty Greatly, low precision, low production efficiency.
The content of the invention
It is an object of the present invention to provide a kind of split type three even take turns, solve existing independent body three and even take turns all processing difficult problems.
This split type the three of the present invention even take turns, and shape even takes turns identical with independent body three, and there is decile axial direction rectangle in hole in gear Keyway, it is characterised in that the independent body three of similar shape is connected into wheel and splits into three gear parts, by the external profile diameter area of complete gear wheel It is divided into middle gear, gear wheel, little gear;Attachment structure is entrenched in one for an end slot of middle gear along the groove of insertion gear wheel Rise, the axial notch of the raised embedded little gear of the gear wheel other end, edge coincide, and it is convex to be stuck in little gear circular arc with elastic spring Play banding in the arc groove of outer wall and the deep-slotted chip breaker of gear wheel projection integral.
One three is connected wheel and is decomposed into three parts by the present invention, changes the shape of each junction, and reconnection is integrated.Use The endoporus that Shi Yinsan even takes turns will install splined shaft, therefore its intensity is unaffected.Split type three connect wheel construction simply, and processing is set It is standby to require low, convenient processing, and while improve machining accuracy, processing cost is reduced on the contrary.Based on this innovation mode, The different gear shapes combination of transmission needs can be met, processing reconnection is splitted integral, it is not necessary to provide special equipment for this, Improve three working (machining) efficiency, the reduces costs for even taking turns like parts.

Specific embodiment
Below in conjunction with the accompanying drawings and example illustrates the structure of split type three-speed gear of the invention
This split type three even take turns, and shape even takes turns identical with integral type three, sees Fig. 1, and there is decile axial direction rectangle in hole in gear Keyway, it is characterised in that the independent body three of similar shape is connected into wheel and splits into three gear parts, by the external profile diameter area of complete gear wheel It is divided into middle gear 1, gear wheel 2, little gear 4;Attachment structure is interior simultaneously along the groove of insertion gear wheel 2 for an end slot of middle gear 1 Rotation, connects two keyways, the axial notch of the raised embedded little gear 4 of the other end of gear wheel 2, the connection of two keyways, and uses steel wire It is integral with banding in the deep-slotted chip breaker of the projection of gear wheel 2 that back-up ring 3 is stuck in the circular arc of the little gear 4 projection arc groove of outer wall.
See that middle gear 1 is shaped as in Fig. 2 a, 2b:The one end of middle gear 1 is with teeth, the most of opposite contracting of the cylindrical radial direction of the other end Footpath, retains and outer wall one, two circular arc projections of radial symmetric, and circular arc projection thickness forms inner circle with remaining frustum cone height Platform.
Fig. 3 a~3c sees the shape of gear wheel 2:The maximum cylindrical of gear wheel 2 is teeth portion, and there are undergauge platform, undergauge in teeth portion one end Size is more than tooth height, and undergauge platform re-forms the circular arc projection for only retaining two radial symmetrics on opposite axial direction arc notch, platform, And circular arc projection outer wall has deep-slotted chip breaker;Teeth portion opposite side is central diameter, and central diameter is more than tooth with diameter greater than undergauge platform diameter, axial length Height;The land of central diameter neighbour's other end, land diameter is less than root portion diameter, radial direction of the land outer end in the outside half of endoporus Part is axial notch, and axial notch is radially, have radial strut at two lack be longer than remaining position and with phase in land Adjacent another axial notch connection, the short radial strut in remaining position of land outer end lacks the annular groove for constituting two symmetrical notches, gear wheel 2 Long radial strut lacks coincide raised with the circular arc of the radial symmetric of middle gear 1.
From the shape of little gear 4 in terms of Fig. 4 a, 4b:Maximum cylindrical side is teeth portion, and at one end, teeth portion is another for the teeth portion of little gear 4 Side is round platform, and round platform diameter is less than root diameter, and there is opposite arc axial direction notch at round platform end, and axial notch is highly less than residue Frustum cone height, in two circular arcs projection that axial notch is formed, the outer wall in height stage casing has arc groove.
As shown in (Fig. 2), the maximum cylindrical of gear 1 is gear tooth, and it is two symmetrical bossings that side is cylindrical, convex The outside for playing part is circular arc, and hole is rectangle keyway in gear, and gear both sides are plane
As shown in (Fig. 3), gear 2 it is maximum cylindrical for gear tooth, gear side is that the inner circular with side edge is recessed , along being above two symmetrical recesses, it is circular arc that recess is inboard, and opposite side is two symmetrical projections for groove, wherein side Part, bossing outside is circular arc simultaneous with circular groove, and hole is rectangle keyway in gear, and gear both sides are plane
As shown in (Fig. 4), gear 4 it is maximum cylindrical for gear tooth, gear side is two recesses, recess Inboard be plane, recess side it is cylindrical on have circular groove, in gear hole be rectangle keyway, gear both sides are flat Face.
Gear 1 is linked together by the bossing on right side with the groove in the left side of gear 2, and gear 2 is convex by right side Play part to link together and be stuck in outside gear 2 and gear 4 with axle-steel silk back-up ring 3 with the recess in the left side of gear 4 In circular groove.So make gear become split type from monoblock type, improve working (machining) efficiency, reduce manufacturing cost.
