Abstract

The invention provides a floating structure of combined herringbone gear inner gear rings. A planet gear is meshed with the inner gear ring A and the inner gear ring B, the inner gear rings and a floating gear ring are connected through a gear coupling, the floating gear and a connecting cylinder are connected through a gear coupling, a positioning plate is fixedly connected with the floating gear ring, a gap exists between the end face at the right side of the inner diameter of the positioning plate and the end face of the connecting cylinder in the assembling process, the two inner gear rings are axially positioned through a flange face at the right end of the connecting cylinder and a flange face at the left end of the floating gear ring and connected with the floating gear ring through the gear coupling, and gears are bevel gears symmetrically arranged. As the steering and rotation direction of the two semi simple bevel gear rings are reasonably matched, meshing axial force is offset, and the structural size is reduced; the flange faces of the structure parts are used for axial positioning, and compared with the mode of positioning through a clamping groove and a retainer ring, the strength of the thin-wall gear rings is effectively prevented from being weakened; the inner gear rings are not provided with fixed radial supports, the two-layer couplings are allowed to shift in the radial or angular direction and have good uniform load performance; the structure is more compact, and the assembling and disassembling manufacturability is good.

Description

A kind of combination herringbone gear ring gear floating structure
technical field:
The present invention relates to double helical tooth planetary gear transmission technology field, specifically a kind of combination herringbone gear ring gear floating structure.
background technique:
High speed high pulling torque Planetary Gear Transmission requires normal employing herringbone gear structure according to bearing capacity and transmission stability, because assembling needs usually ring gear to be designed to two halves monocline tooth assembling form, whether reasonable its structural type is has material impact to the gear-driven performance of double helical tooth planetary, needs to consider structural strength, all carry the many factors such as performance and dismounting process when designing.
summary of the invention:
For the problems referred to above, the invention provides a kind of combination herringbone gear ring gear floating structure.
Technological scheme of the present invention is: a kind of combination herringbone gear ring gear floating structure, comprise planet wheel, planet wheel is meshed with ring gear A ring gear B respectively, two ring gears are connected by gear coupling with floating gear ring, the gear ring that floats is connected by gear coupling with coupling tunnel, positioning plate is connected firmly by bolt and floating gear ring, positioning plate internal diameter its right end face assembling time and coupling tunnel end face there is gap, two ring gears pass through the flange surface axially locating of coupling tunnel right-hand member and floating gear ring left end, have certain micro-gap during equipment adjustment.
Two described ring gears are connected by gear coupling with floating gear ring, and its gear is helical gear, and helical gear oblique angle is arranged symmetrically with.
The present invention has following beneficial effect: herringbone gear ring gear combination floating structure of the present invention makes engagement axial force cancel out each other by turning to of Proper Match two halves monocline gear ring with rotation direction, reduces physical dimension; Utilize structural member flange surface axially locating, compare draw-in groove collar positioning form and efficiently avoid weakening to thin-walled gear ring intensity; Ring gear supports without fixed radial, and two-layer coupling has allowed radial direction and angular displacement, has good all to carry performance; Structure is compacter, and dismounting process is good.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Accompanying drawing 2 is stressed schematic diagram of ring gear 4,6 in the present invention.
1-coupling tunnel in figure, 2-positioning plate, 3-bolt, 4-ring gear A, 5-float gear ring, 6-ring gear B, 7-planet wheel.
embodiment:
Below in conjunction with accompanying drawing, the invention will be further described:
Shown in Fig. 1 composition graphs 2, a kind of combination herringbone gear ring gear floating structure, comprise planet wheel 7, planet wheel 7 is meshed with ring gear A4 ring gear B6 respectively, two ring gears 4, 6 are connected by gear coupling with floating gear ring 5, the gear ring 5 that floats is connected by gear coupling with coupling tunnel 1, positioning plate 2 is connected firmly by bolt 3 and floating gear ring 5, positioning plate 2 internal diameter its right end face assembling time and coupling tunnel 1 end face there is gap, two ring gears 4, 6 by the flange surface axially locating of coupling tunnel 1 right-hand member and floating gear ring 5 left end, certain micro-gap is had during equipment adjustment.
Described two ring gears 4,6 are connected by gear coupling with floating gear ring 5, and its gear is helical gear, and helical gear oblique angle is arranged symmetrically with.
Compare draw-in groove collar positioning form and efficiently avoid weakening to thin-walled gear ring intensity, by coupling engaging gear turn to rotation direction, gear transmission is worked time the axial force direction that is subject to of two ring gears point to two ring gear surface of contact, while offsetting engagement axial force, turn avoid the rigid joint of two ring gears, make two ring gear tooth forces evenly, a gear coupling transmitting torque, effectively reduce structural member size, allow ring gear that radial and angular displacement occur by two-layer gear coupling, automatically locate when making stand under load unbalanced, reach and all carry object, simultaneously, without locating groove on floating gear ring, wall thickness can be reduced to greatest extent, increase flexibility, effectively ensure all carrying between each planet wheel further.
Technical problem to be solved by this invention is: the torsion pass performance being realized the separable assembled of herringbone gear ring gear, floating load balancing and Geng Gao by rational structural design; There is good dismounting process simultaneously.
