Bearing 16 or slipper push internal tooth casing 13 slide.When rocking arm rotates, drivening rod is swung so as to by deep groove ball bearing 16 or sliding
Block promotion internal tooth casing 10 horizontally slips to reach the purpose of change gear-box speed ratio.
In the shifting fork structure shown in Fig. 5, because the linear velocity along the outer ring width of deep groove ball bearing 16 is different, make
Bearing fragmentation is frequently resulted in during, even if deep groove ball bearing 16 has been changed into sliding block made of copper, although before solving
Fragmentation problem, but due to sliding block and the chute of internal tooth casing 10 to be frequently slidably connected and linear velocity is higher, for a long time using rear slider
Abrasion is more serious, it is necessary to regularly replace sliding block.
Utility model content
The purpose of this utility model is：It is easy for the deep groove ball bearing that is used in traditional power shift gear case shifting fork mechanism
Fragmentation, and sliding block rear slider and internal tooth casing chute are used instead to be frequently slidably connected and linear velocity is higher, it is sliding after long-time use
Block abrasion is more serious, it is necessary to regularly replace the practical problem of sliding block, there is provided a kind of shifting fork mechanism of new power shift gear case.
What the purpose of this utility model was realized in：A kind of shifting fork mechanism of power shift gear case, including it is rocking arm, axle, fixed
Away from ring, symmetrical connecting rod and pulling axis, it is characterised in that the top of described a pair of links is provided with corresponding bearing block, and pulling axis leads to
Copper sheathing to be crossed to be positioned in bearing block, copper sheathing is pressed in the bearing block of connecting rod by gland, is fixed gland and connecting rod by two bolts,
There is an oil trap at the top of gland, an oil duct is provided with gland, copper sheathing is provided with oilhole, and the entrance of oil duct is located at oil trap
In, the end of oil duct and the oilhole of copper sheathing are linked up, and the lubricating oil in oil trap is arrived at copper sheathing by described oil duct and oilhole and dialled
The movable joint of axle.
In the utility model, described axle is fixed on axle by bearings and casing, a pair of links, two connecting rods it
Between positioned by distance collar on axle；Internal tooth casing outer wall is provided with corresponding allocating slot, is positioned at the pulling axis at the top of connecting rod and is placed in pair
In the allocating slot answered, internal tooth casing slides under the driving of pulling axis on the external tooth cover of power transmission shaft.
In the utility model, one end of axle is passed through casing and is connected with rocking arm.
In the utility model, for the screw cap end by two bolts of fixing gland and connecting rod for square or just
Hexagon, through hole is provided between the relative edge of nut, gland and connecting rod are fixed, two bolts are by passing through through hole
Iron wire is in the anti-loosening locking of the figure of eight.
The utility model has the advantage of：Due to pulling axis to be substituted to traditional deep groove ball bearing or sliding block, its mounting means
The top for being changed to a pair of links is provided with corresponding bearing block, and pulling axis is positioned in bearing block by copper sheathing, and gland is by copper sheathing pressure
In the bearing block of connecting rod, gland and connecting rod are fixed by two bolts, can be rotated automatically in the work of its pulling axis, this rotation
Although similar to the outer ring of deep groove ball bearing, but not breaking up, compared with traditional sliding block, its rotation can reduce surface
Abrasion, extends its service life.Due to there is an oil trap at the top of described gland, an oil duct, copper sheathing are provided with gland
Oilhole is provided with, the entrance of oil duct is located in oil trap, and the end of oil duct and the oilhole of copper sheathing are linked up, the lubricating oil in oil trap
The movable joint of copper sheathing and pulling axis is arrived at by described oil duct and oilhole, lubrication can be provided to movable joint, reduce mill
Damage reduces mechanical loss.Because the screw cap end by two bolts for gland and connecting rod to be fixed is square or positive six side
Shape, through hole is provided between the relative edge of nut, gland and connecting rod are fixed, two bolts are by passing through the iron wire of through hole
In the anti-loosening locking of the figure of eight, superstructure loosening is avoided to influence the normal operation of equipment.The utility model is compact-sized, maintenance side
Just.
