Abstract
The utility model discloses a duplicate gear which comprises a coupling band, a minor-diameter gear ring is fixedly installed at one end of the coupling band, a major-diameter gear ring is fixedly installed at the other end of the shaft coupling sleeve, a gap is installed between the minor-diameter gear ring and the major-diameter gear ring, and the end face of the major-diameter gear ring is provided with a pin shaft hole. The duplicate gear is high in structure strength, improves load capacity obviously, is matched with a shaft body conveniently and firmly, and effectively improves stability of gear transmission.
Description
Technical field
The utility model relates to a kind of duplicate gear.
Background technique
Common duplicate gear is made up of gear with holes and integrated type joint shaft gear, and gear with holes is gone up composition duplicate gear structure through the axle that interference fit is connected the integrated type joint shaft gear.On the axle of integrated type joint shaft gear, be connected the position that cooperates and be provided with straight knurling with gear with holes.This kind gear exists the irrational phenomenon of structural design, and difficulty of processing is big, and bulk strength is not high.
The model utility content
The purpose of the utility model provides a kind of duplicate gear, and structural strength is high, and load capacity obviously increases, and it is firmly convenient to cooperate with axis body, has effectively improved gear-driven stability.
The technological scheme of the utility model is following:
A kind of duplicate gear includes coupling band, and an end of coupling band is fixed with the path gear ring, the other end is fixed with big footpath gear ring, has the gap between path gear ring and the big footpath gear ring, has pin shaft hole on the end face of big footpath gear ring.
Have locking hole on the described coupling band sidewall.
The structural strength of the utility model is high, and load capacity obviously increases, and it is firmly convenient to cooperate with axis body, has effectively improved gear-driven stability.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing, a kind of duplicate gear includes coupling band 1; One end of coupling band 1 is fixed with path gear ring 2, the other end is fixed with big footpath gear ring 3; Have the gap between path gear ring 2 and the big footpath gear ring, have pin shaft hole 4 on the end face of big footpath gear ring, have locking hole 5 on the coupling band sidewall.
Claims (2)
1. a duplicate gear includes coupling band, it is characterized in that: an end of coupling band is fixed with the path gear ring, the other end is fixed with big footpath gear ring, has the gap between path gear ring and the big footpath gear ring, has pin shaft hole on the end face of big footpath gear ring.
