Abstract
The utility model relates to a zero side gap planetary gear transmission mechanism, which is equipment to be applied in a packaging machinery industry. The utility model is characterized in that 1 to (n-1) planetary gears are firstly connected with a threaded bolt of a flanged disc which is provided with an arc-shaped slot among the planetary gears which are arranged on a drive roll axis and are engaged with a sun gear; secondly, the flanged disc is connected with shaft keys of the planetary gears; the other planetary gears are directly connected with the shaft keys of the other planetary gears. The utility model has the advantage that errors of printing, slotting and die cutting are reduced from the original error which is more than 3 millimeters to the existing error which is less than 0.5 millimeter in order to enhance more than 6 times of accuracy.
Description
The utility model relates to a kind of gear drive of mechanical industry, and the suffered load of active roll in the equipment such as particularly a kind of printing that is applicable to package packing machine, fluting, cross cutting is the planetary gear mechanism under the situation of being interrupted load.
The suffered load of its initiative roll shaft is interruption load in the equipment work processes such as the printing of package packing machine, fluting, cross cutting at present, and this just makes traditional gear backlash bring bigger error for printing, fluting, cross cutting.And print, the precision of fluting, cross cutting just is to weigh the major technique quality index of these equipment, therefore, reduces and eliminates the transmission sideshake of initiative roll shaft gear, the precision of raising printing, fluting, cross cutting has just become a key issue in these equipment.
The purpose of this utility model is to provide a kind of zero sideshake planetary gear mechanism.
The purpose of this utility model is achieved in that a kind of zero sideshake planetary gear mechanism, with the I sun gear is input end, through the I planetary pinion, the II planetary pinion, the n planetary pinion passes tie-rod by its axle respectively and connects I ' number planetary pinion, II ' number planetary pinion, n ' number planetary pinion, be transferred to the II sun gear again and connect initiative roll shaft by it, it is characterized in that: I ' number planetary pinion, II ' number planetary pinion, have 1 at first to be connected to (n-1) individual planetary pinion in n ' number planetary pinion with a flange plate bolt that has arc slot, be connected with this planetary pinion axle key by flange plate, remaining planetary pinion directly is connected with its axle key again.
The utility model has been broken through traditional gear backlash transmission, has realized zero sideshake planetary pinion transmission, under equal conditions, the error of printing, fluting, cross cutting by being reduced to below the 0.5mm more than the original 3mm, is improved precision more than 6 times.
Elaborate below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation
Fig. 2 is the right elevation of Fig. 1
Fig. 3 is the I portion enlarged view of Fig. 2
Fig. 4 is the II portion enlarged view of Fig. 2
As shown in the figure, be that 2 planetary pinion is an example with the planet number of teeth, setting tie-rod 4 rotating speeds is zero (being that tie-rod 4 is fixing), then this planetary pinion transmission has only an input, an output.With I sun gear 1 is input end, also pass tie-rod 4 by its axle respectively through I planetary pinion 2, II planetary pinion 3 and connect I ' number planetary pinions 5, II ' number planetary pinion 6, be transferred to II sun gear 8 again, and be connected with the active roll axle key by it.I ' number planetary pinion 5, II ' number planetary pinion 6 one of them (being illustrated as planetary pinion 6) are connected with flange plate 7 bolts of a band arc slot, are connected with this planetary pinion axle key by flange plate 7 again, and another then directly is connected with its axle key.During installation, along flange plate 7 circumferencial direction turns fine setting, make its tooth and II sun gear 8 teeth II ' number planetary pinion 6, use bolt then in reverse no gap (as shown in Figure 4).Like this II sun gear 8 (initiative roll shaft gear) is clamped between the engaging tooth of I ' number planetary pinion 5, II ' number planetary pinion 6, the actual sideshake of II sun gear 8 is zero, has realized zero sideshake planetary pinion transmission.(n 〉=2 when the planetary pinion number is n, n is a positive integer) can design 1 and at first be connected to (n-1) individual planetary pinion with flange plate 7 bolts that have arc slot, be connected with this planetary pinion axle key by flange plate 7, the direct connection with its axle key of remaining planetary pinion gets final product again.
