Description
Technical field
The utility model is mainly used in revolution class epicyclic gearbox slow speed turbine stage planet carrier axial limiting occasion, particularly one revolution class epicyclic gearbox planet carrier axially stop block.
Background technique
Employing basic building block is the revolution class epicyclic gearbox of floating load balancing mechanism, the axial clearance leaving 0.5 ~ 1.0mm is needed between the two ends of its each floating member and adjacent parts, otherwise, not only can affect and float and effect of load balancing mechanism, also can cause frictional heating and produce noise.
Axial limiting is carried out to slow speed turbine stage planet carrier, common way is: carry out axial limiting by the end face of sun gear to planet carrier, or planet carrier jump ring is fixed on sun gear or on body, the axis being realized planet carrier by the axial limiting of sun gear or body is spacing.But at some in particular cases, planet carrier is difficult to by sun gear end face spacing, or be difficult to spacing for planet carrier on sun gear or on body.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of revolution class epicyclic gearbox planet carrier axially stop block, and this apparatus structure is simple, is easy to processing, easy for installation, economical convenient; The utility model has the features such as adjustable, floating stability good, dismounting process is good; In addition, compare other limit method, the structure of planet carrier is more simple, can reduce the manufacture cost of planet carrier.
In order to achieve the above object, the technical solution of the utility model is:
A kind of revolution class epicyclic gearbox planet carrier axially stop block, comprise limited ring 2, limited ring 2 is arranged in draw-in groove that body 1 is processed on the left of tooth, and the internal tooth 6 of limited ring 2 engages with the external tooth 5 of body 1, body 1 engages with planet carrier 4 and assembles, the transverse tooth thickness of limited ring 2 and tooth space centerline all align with the transverse tooth thickness of body 1 and tooth space centerline, and limited ring 2 is connected by bolt 3 after closing with planet carrier 4.
Described limited ring 2 and the planet carrier 4 internal tooth number of teeth are z, and the internal tooth 6 opposing rows carrier 4 internal tooth angle of swing 360 °/z place of limited ring 2 is processed with bolt connecting hole.
The utility model is that a tooth being processed with the limited ring of internal tooth is along the annular slot on the teeth groove loading body of fixing body, then the external tooth of the relative body of limited ring internal tooth rotates in a circumferential direction a small angle, the internal tooth of limited ring has just been blocked by the external tooth of body, limited ring and slow speed turbine stage planet carrier are bolted, thus achieve the axial limiting to slow speed turbine stage planet carrier.
The utility model has the features such as adjustable, floating stability good, dismounting process is good; This structure is simple, is easy to processing, easy for installation, economical convenient.In addition, compare other limit method, the structure of planet carrier is more simple, can reduce the manufacture cost of planet carrier 4.

Fig. 1 is assembling front view of the present utility model.
Fig. 2 is body 1 partial schematic diagram when engaging with limited ring 2.
Fig. 3 is body 1 external tooth 5 partial schematic diagram when staggering with limited ring 2 internal tooth 6.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
With reference to Fig. 1, a kind of revolution class epicyclic gearbox planet carrier axially stop block, comprise limited ring 2, limited ring 2 is arranged in draw-in groove that body 1 is processed on the left of tooth, with reference to Fig. 2, Fig. 3, and the internal tooth 6 of limited ring 2 engages with the external tooth 5 of body 1, body 1 engages with planet carrier 4 and assembles, and the transverse tooth thickness of limited ring 2 and tooth space centerline all align with the transverse tooth thickness of body 1 and tooth space centerline, and limited ring 2 is connected by bolt 3 after closing with planet carrier 4.
Described limited ring 2 and the planet carrier 4 internal tooth number of teeth are z, and the internal tooth 6 opposing rows carrier 4 internal tooth angle of swing 360 °/z place of limited ring 2 is processed with bolt connecting hole, insert fixing for bolt 3.
Working principle of the present utility model comprises the following steps:
One, planet carrier is in assembly process, and limited ring 2 is engaged with body 1 external tooth 5 by its internal tooth 6, and limited ring 2 is arranged in draw-in groove that body 1 is processed on the left of tooth;
Two, body 1 carries out engaging with planet carrier 4 and assembles, then, limited ring 2 circumferencial direction angle of swing 360 °/z, z is the internal tooth number of teeth of limited ring 2, bolt hole on limited ring 2 and planet carrier 4 is alignd, and now the transverse tooth thickness center line of limited ring 2 and the transverse tooth thickness center line of body 1 align, and the tooth space centerline of limited ring 2 and the tooth space centerline of body 1 align, limited ring 2 and planet carrier 4 use bolt 3 to carry out bolt connection
Three, the internal tooth 6 of limited ring 2 is blocked by the external tooth 5 of body 1, cannot deviate from, thus achieve the axial limiting of limited ring 2 and planet carrier 4.
The planet carrier 4 of epicyclic gearbox slow speed turbine stage of the present utility model is stuck in the middle of the trough on fixing body 1 by the limited ring 2 that is processed with internal tooth 6, the tooth of limited ring 2 loads draw-in groove along the teeth groove of body, then the external tooth 5 of the relative body 1 of limited ring 2 internal tooth 6 rotates in a circumferential direction an angle, the tooth of limited ring 2 has just been blocked by the external tooth 5 of body 1, the planet carrier 4 of limited ring 2 and slow speed turbine stage is bolted, thus achieves the axial limiting to slow speed turbine stage planet carrier.
