Further, the stepped hole is macropore in big cylindrical section, is aperture in roundlet shell of column.
It further, further include protection bushing, the aperture interference fit of the protection bushing and stepped hole.
Further, the center line of the excessive cylinder of extended line a, b of two sections of the opening；In the big cylinder
Heart line makees the axis that straight line c connects the location hole.
Further, the angle of the straight line c and extended line a is 0~± 15 °.
Further, the angle of the straight line c and extended line b is 0~± 15 °.
Further, the arc-shaped sheet of the balance weight, radius are matched with the radius of the annular groove.
Further, the outer peripheral surface of the small column is equipped with annular knurl.
The beneficial effect that the utility model is compared with the prior art includes:
(1) using crankshaft as bearing, the design and use of supporting element are reduced, saves operating space；
(2) region of engagement of timing gears and idle gear is stuck in by the opening section of cutting ferrule, thus clamping gear, the clamping
Mode is versatile, regardless of idle gear size, the present apparatus can be used to carry out clamping, be suitable for promoting the use of；
(3) add protection bushing, scratch crankshaft diameter when preventing from being fastened in compression；
(4) deflecting force being fastened in crankshaft diameter is adjusted, using balance weight so as to adjust the steering of cutting ferrule under normal conditions
Trend, i.e., when balance weight is routed up, cutting ferrule is because of the gravity by balance weight, the direction rotation that oriented balance weight is routed up, when
When balance weight withdraws annular groove, turn to opposite with the steering routed up；
(5) in actual operation, the central junction line of timing gears and idle gear is parallax, and the position of balance weight is necessary
In a certain range, can just play the role of adjusting cutting ferrule steering；
(6) when balance weight progress gear clamping operation is not arranged, cutting ferrule is easy bounce pop-up region of engagement, it is seen then that balances
Block also acts as quick detent, improves the stability of clamping process.
Detailed description of the invention
Fig. 1 is the utility model top view；
Fig. 2 is the utility model main view；
Fig. 3 is cutting ferrule cross-sectional view；
Fig. 4, Fig. 5 are the utility model using renderings.
Specific embodiment
With reference to embodiment and compares attached drawing the utility model is described in further detail.It should be emphasized that
It is that following the description is only exemplary, rather than in order to limit the scope of the utility model and its application.
Referring to the following drawings, non-limiting and nonexcludability embodiment will be described, wherein identical appended drawing reference indicates
Identical component, unless stated otherwise.
A kind of gear rotation stop card cover device as shown in Figs. 1-5, applies the clamping in engine gear system, including cutting ferrule
2, by the coaxial boss of small one and large one two cylinder organization centers, and the stepped hole through its upper and lower end face is offered, it is described
Stepped hole is macropore 22 in big cylindrical section, is aperture 23 in roundlet shell of column.The junction of two cylinders offers annular groove 6, greatly
The joint surface of small two cylinders offers axially position hole 41, and the outer peripheral surface of small column is equipped with annular knurl 5, and the side wall of big cylinder opens up
Have opening 21, be open 21 width be greater than region of engagement width.
Referring again to Fig. 1, the center line of the excessive cylinder of extended line a, b of two sections of the opening 21.According to starting
The rigging position of machine timing gears 71 and idle gear 8, idle gear 8 is in the upper right side of timing gears 71, location hole in the present embodiment
41 are provided with the left side of timing gears 71, guarantee balance weight 3 when routing up annular groove 6, with idle gear 8 not in timing gears 71
The same side, preferably to play the adjustment effect of balance weight 3.Using the center line of big cylinder as starting point, make auxiliary straight line c connection
The angle of the central axis of the location hole 41, the straight line c and extended line a are 0~± 5 °.The arc-shaped sheet of balance weight 3 is simultaneously
It is arranged in the annular groove 6, thickness is less than the width of annular groove 6, and radius is matched with the radius of the annular groove 6.It is flat
The end of weighing apparatus block 3 offers connecting hole, and positioning pin 4 passes through the connecting hole and close-fitting in location hole 41, and balance weight 3 is around positioning pin
4 rotations, to realize that balance weight 3 is routed up in cutting ferrule 2 and withdrawal annular groove 6, to control the rotation trend of cutting ferrule 2 under normal conditions.
It protects the stepped hole of bushing 1 and roundlet shell of column to be interference fitted, prevents cutting ferrule 2 from scratching 7 diameter of axle of crankshaft when being pressurized.
