Abstract
The utility model belongs to mechanical designing technique, relates to a kind of gear crack-stop structure.It comprises the first gear piece (1), gear piece (2), gear (3).It is characterized in that, first gear piece (1) with identical parameters is connected by certain Placement with gear piece (2), forms a driving gear; Gear (3) comprises the identical gear piece of two panels parameter; First gear piece (1) and gear piece (2) engage with two gear pieces of gear (3) respectively, form driving mechanism.The utility model is in mechanical transmission, driving gear crackle causes gear capacity to decline, gear life is caused sharply to decline, even there is the fault mode that gear breaking, transmission system are stuck, a kind of mechanical structure form preventing gear crack from spreading is proposed, realize the design of transmission system mechanical redundancy, reduce transmission system mission failure rate, improve auxiliary products reliability.
Description
Technical field
The utility model belongs to mechanical designing technique, relates to a kind of gear crack-stop structure.
Background technique
At present, aircraft rudder surface actuator adopts hydraulic product mostly, but along with the development of electric aircraft, electronic product replaces hydraulic product to become trend.Solve the mechanical remaining problem of electronic product transmission part, improve reliable transmission, thus improve mission reliability, ensure flight safety, become electronic product and replaced one of bottleneck of hydraulic product operating aircraft main rudder face development.
Model utility content
The purpose of this utility model is: propose a kind of gear crack-stop structure, realizes the design of transmission system mechanical redundancy, reduces transmission system mission failure rate, improve auxiliary products reliability.
The technical solution of the utility model is: a kind of gear crack-stop structure, comprises the first gear piece 1, gear piece 2, gear 3, and first gear piece 1 with identical gear parameter is connected with gear piece 2, forms a driving gear; Gear 3 is also driving gear, comprises the gear piece of the identical gear parameter of two panels; First gear piece 1 and gear piece 2 engage with two gear pieces of gear 3 respectively, form driving mechanism.
Preferably, between the first gear piece 1, gear piece 2, and be separated type between gear 3 two panels gear piece, adopt spline or bolt mode to connect.
Preferably, gear 3 two panels gear piece is formed in one.
The utility model has the advantages that: the utility model, by each driving gear is designed to two panels toothing, realizes the mechanical redundancy design of transmission system, improves reliable transmission, thus improve mission reliability, promote flight safety further.Often organize driving gear and be two redundancy design, realize a slice gear crack, do not affect whole transmission system reliable operation.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model structure;
Fig. 2 is the sectional view in the utility model structure A-A face.
Embodiment
Below the utility model is described in further details.
See Fig. 1 and Fig. 2, a kind of gear crack-stop structure, comprises the first gear piece 1, gear piece 2, gear 3, and first gear piece 1 with identical gear parameter is connected with gear piece 2, forms a driving gear; Gear 3 is also driving gear, comprises the gear piece of the identical gear parameter of two panels; First gear piece 1 and gear piece 2 engage with two gear pieces of gear 3 respectively, form driving mechanism.
Between first gear piece 1, gear piece 2, and be separated type between gear 3 two panels gear piece, adopt spline or bolt mode to connect.
In addition, the two panels gear piece of gear 3 also can be designed as one-body molded.
The utility model is often organized driving gear and is two redundancy design, realizes a slice gear crack, does not affect whole transmission system reliable operation.
