Description
Technical field
The utility model relates to synchronized processing technique field, is specifically related to a kind of synchronized clutch collar gear hobbing clamping device.
Background technology
Because transmission input shaft and engine output shaft rotate with respective speed, during conversion gear, " synchronously " problem can be there is.Two different gears of rotary speed engage by force and impact will inevitably occur, and damage gear.Therefore, the gear shift of old-fashioned speed changer will adopt the mode of " bipod clutch ", upshift neutral position stop a moment (but clutch need lift, object is to allow clutch disc also want and flywheel synchronization, just rotating speed must unanimously can engage a gear smoothly, if it is slow to shift gears, rotating speed falls idling, also cannot hang into), downshift will at neutral position (keep clutch lift) open out simultaneously, to reduce the speed discrepancy of gear.But this operates more complicated, be difficult to grasp accurately.Therefore designer creates " synchronized ", makes to reach consistent rotating speed and engage smoothly by meshed gears by synchronized.
Synchronized, it is primarily of compositions such as clutch collar, synchronous lock rings, and its feature relies on rubbing action to realize synchronously.
The gear ring of clutch collar, synchronous lock ring and gear to be joined all has chamfering (angle of lock), and the inner conical surface of synchronous lock ring contacts to produce with gear-wheel gear-ring male cone (strobilus masculinus) to be joined and rubs.Suitable selection done by angle of lock and the conical surface when designing, conical surface friction makes tooth cover to be engaged synchronous rapidly with gear ring, can produce again a kind of locking effect simultaneously, prevent gear from engaging at advanced in unison row.
After synchronous lock ring inner conical surface contacts with gear-wheel gear-ring male cone (strobilus masculinus) to be joined, (or rising) is reduced rapidly to equal with synchronous lock ring rotating speed at the effect lower gear rotating speed of moment of friction, both synchronous rotaries, gear is zero relative to the rotating speed of synchronous lock ring, thus moment of inertia also disappears simultaneously, at this moment under the promotion of active force, clutch collar engages with synchrolock annular gear in the clear, and engage with the gear ring of gear to be joined further and complete gearshift procedure, at present when clutch collar cylindrical gear hobbing process, inventor encounters a difficult problem, because clutch collar endoporus is provided with spline, existing clutch collar fixture simple and quick fixed engagement effectively cannot overlap main part, cause cylindrical gear hobbing process efficiency low.
