Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below technical solutions of the utility model are described in detail, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, a kind of transmission device for Pressesservo that the utility model provides, comprises power input block 1 and duplex helical gear deceleration device 2.Wherein, power input block 1 comprises servomotor 101 and shaft coupling 102, and shaft coupling 102 is diaphragm type shaft coupling.Duplex helical gear deceleration device 2 comprises gear housing 201, gear housing 201 is provided with driving gear shaft 202 and driven gear shaft 203, wherein, single-groove grooved ball bearing 204 is inserted in one end of driving gear shaft 202, the other end is inserted in Biserial cylindrical roller bearing 205, single-groove grooved ball bearing 24 and Biserial cylindrical roller bearing 205 are all arranged on gear housing 201 by bearing block, gland is provided with after the bearing block that Biserial cylindrical roller bearing 205 is inserted in, outside framework oil seal is equipped with in the place that gland contacts with driving gear shaft 202, the axis of driving gear shaft 202 can move.Driven gear shaft 203 be arranged on gear housing 201 by two single-groove grooved ball bearings 204, wherein the front portion of the single-groove grooved ball bearing 204 of one end is provided with baffle ring 206 and positions, one group of back-to-back outside framework oil seal is provided with outside baffle ring 206 and between gear housing 201, thus prevent the lubricating oil string of the lubricating oil in gear housing 201 and punch press oily, the single-groove grooved ball bearing 204 of the other end is arranged in bearing block, the pressured lid of bearing block positions, and outside framework oil seal is equipped with in the place that gland contacts with driven gear shaft 203.Driving gear shaft 202 is provided with driving tooth wheels, and driving tooth wheels are fixedly formed side by side by a left-handed gear 207 of active and an active dextrorotation gear 208; Initiatively left-handed gear 207 and active dextrorotation gear 208 are fixed by pretension bolt, simultaneously by connecting pin location also transmitting torque; The gear teeth composition of two gears " people " the font gear teeth, the helical angle of the left-handed gear 207 of active and initiatively dextrorotation gear 208 is 15 ° wherein, and driving gear shaft 202 is preferably made of one with the left-handed gear 207 of active.Driven gear shaft 203 is provided with driven tooth wheels, and driven tooth wheels are arranged on driven gear shaft 203 by moment of torsion set of books; Driven tooth wheels are fixedly formed side by side by a driven left-handed gear 209 and a driven dextrorotation gear 210; Driven left-handed gear 209 and driven dextrorotation gear 210 are fixed by pretension bolt, simultaneously by connecting pin location also transmitting torque; The gear teeth composition of two gears " people " the font gear teeth, the helical angle of driven left-handed gear 209 and driven dextrorotation gear 210 is 15 °.In the rear end of driven gear shaft 203, brake gear 211 is housed, wherein, brake gear is connected with driven gear shaft by key.Wherein, driving tooth wheels position by driven tooth wheels, and driving tooth wheels drive the work of driven tooth wheels.Servomotor 101 is connected with driving gear shaft 202 by shaft coupling 102.
When servomotor 101 works, servomotor 101 drives driving gear shaft 202 to rotate by shaft coupling 102, driving tooth wheels drive driven tooth wheels to rotate, radius due to driven tooth wheels middle gear is greater than the radius of driving tooth wheels middle gear, so the rotating speed that the rotating speed that driven gear shaft 203 exports produces lower than servomotor, thus play the effect of deceleration.The utility model adopts the deceleration device of duplex helical gear structure in transmission device, not only make overall structure compacter, more reasonable, and the axial force that transmission is produced is cancelled out each other, and reduces bearing axial load, registration is large, transmission is comparatively steady, is suitable for the occasion that load is larger, and transmission accuracy is high simultaneously, noise is low, and rotating speed is well controlled.Adopt high pulling torque without the non-maintaining all steel diaphragm type coupler of backlash, intensity is high, turns round to good rigidly, and compensate ability is strong; Diaphragm group preloading power, thus improve and turn round to rigidity, solve axial vibration problem, ensure the steady running of system; Adopt high pulling torque cover, gear and gear shaft are more easily processed, and assembling is simple, is easy to operation and maintenance.The application of pneumatic spring formula brake gear, both can avoid unsafe event to occur, can reduce again the load of servomotor, extended the service life of machine.Owing to being equipped with outside framework oil seal in the junction of gear housing and miscellaneous part, so a large amount of gear oil can be contained in gear housing, thus ensure that gear has sufficient lubrication property, decrease gear teeth face wearing and tearing, rippling and tooth face agglutination, improve mechanical drive gear quality, have very important realistic meaning to the service life of prolonged mechanical equipment.
