Abstract
A kind of seven shelves gears, including gear；Through offering mounting hole at the gear center, gear shaft is inserted in mounting hole, along being above provided with fixed part in the mounting hole；Several through-holes are provided in the gear；Relatively fixed portion is provided with slot on the gear shaft.The utility model passes through the cooperation of fixed part and slot, and in assembly, the fixed part of gear need to be only aligned to the slot of gear shaft, that is, can avoid that circumferential movement occurs between gear and gear shaft.
Description
Technical field
The utility model relates to a kind of gear, specifically a kind of seven shelves gear belongs to automotive transmission field.
Background technique
The assembly of existing speed changer middle gear is not secured enough, and circumferential movement is easy to appear between gear shaft and gear, is caused
It slides between the two.
Therefore, it is further improved.
Utility model content
The purpose of this utility model is: providing and a kind of assembles seven stronger shelves gears.
To realize the above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:
A kind of seven shelves gears, including gear；Run through at the gear center and offers mounting hole, gear shaft
It is inserted in mounting hole, along being above provided with fixed part in the mounting hole；Several through-holes are provided in the gear；Institute
It states relatively fixed portion on gear shaft and is provided with slot.
The through-hole is uniformly distributed on the outside of mounting hole；The through-hole has at least two.
The fixed part is the protrusion towards mounting hole the center point.
The fixed part rectangular and trapezoidal shapes.
The through-hole both ends offer stepped hole.
The utility model passes through the cooperation of fixed part and slot, in assembly, only the fixed part of gear need to be aligned gear
The slot of axis can avoid that circumferential movement occurs between gear and gear shaft.
Detailed description of the invention
The utility model can be further illustrated by the nonlimiting examples that attached drawing provides；
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the sectional view of the utility model.
In figure, 1 is gear, and 2 be mounting hole, and 3 be fixed part, and 4 be through-hole, and 5 be stepped hole.
Specific embodiment
It is right with reference to the accompanying drawings and examples in order to make those skilled in the art that the utility model may be better understood
The technical solution of the utility model further illustrates.
Referring to Fig. 1-Fig. 2, a kind of seven shelves gears, including gear 1；Run through at 1 center of gear and offers installation
Hole 2, gear shaft are inserted in mounting hole 2, along being above provided with fixed part 3 in mounting hole 2；It is provided in gear 1 several logical
Hole 4；Relatively fixed portion is provided with slot on gear shaft.
Preferably, through-hole 4 is uniformly distributed in 2 outside of mounting hole；Through-hole has at least two.
Preferably, fixed part 3 is the protrusion towards 2 the center point of mounting hole.
Preferably, 3 rectangular and trapezoidal shapes of fixed part.
Preferably, 4 both ends of through-hole offer stepped hole 5.
Above-described embodiment is merely exemplary to illustrate the principle and effect of the utility model, and not for limitation, this is practical new
Type.Any person skilled in the art can all carry out above-described embodiment under the spirit and scope without prejudice to the utility model
Modifications and changes.Therefore, all those of ordinary skill in the art are without departing from the revealed spirit of the utility model
With all equivalent modifications completed under technical idea or change, should be covered by the claim of the utility model.
