The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer; To combine the accompanying drawing among the utility model embodiment below; Technical scheme among the utility model embodiment is carried out clear, intactly description; Obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Referring to figs. 1 through shown in Figure 4; The flywheel gear 1 of present embodiment electric screw press and the electric screw press of this flywheel gear 1 is installed; Flywheel gear 1 comprises gear wheel 11, screw rod 12, back tightening nut 13, bearing 14, bearing block 15, and gear wheel axle sleeve part 111 is fixedly connected by a plurality of bearing pins 16 with the screw shaft 121 of screw rod 12.
The flywheel gear of present embodiment electric screw press is through being fixedly connected with screw rod gear wheel by a plurality of bearing pins; Guaranteed the axiality of gear wheel and screw rod, it is good that moment is transmitted performance, and the gap is little; Eliminate radially wobbling of gear wheel, greatly improved the service life of equipment.
Gear wheel axle sleeve part 111 with screw shaft 121 by the concrete implementation that a plurality of bearing pins 16 are fixedly connected is: a plurality of bearing pins 16 are fixedly connected on the circumferential contact face place 17 of gear wheel axle sleeve part 111 and screw shaft 121; Be to be distributed on the circumferential contact face of gear wheel axle sleeve part 111 to be provided with a plurality of bearing pins half hole; Correspondingly; Correspondence is offered a plurality of bearing pins half hole on the circumferential contact face of screw shaft 121, forms a plurality of unitary pin axis holes thereby cooperate, each bearing pin 16 and each pin shaft hole interference fits.
For for convenience detach; Bearing pin 16 adopts cylindrical pin with internal thread; Only need adopt finger device and bearing pin top screw-internal thread fit that bearing pin 16 is extracted during dismounting gets final product; The number of bearing pin 16 is 3～8, is distributed on the circumferential contact face 17 of gear wheel axle sleeve part 111 and screw shaft 121, and the number of bearing pin 16 is 6 in the present embodiment.The diameter of bearing pin 16 is 30～100mm, and different, its diameter is 40mm in the present embodiment according to concrete type.
Casting for ease of gear wheel 11 blanks; The processing of part, installation and later period maintenance and replacing, gear wheel 11 adopts split-type structural, comprises gear wheel axle sleeve part 111 and motivation transfer motion part 112 two parts; The two is fixed as one through fastening bolt 2, and split faying face 18 is stepped.So, process respectively with motivation transfer motion part 112 two parts, thereby reduced the processing technology of gear wheel 11, improved working (machining) efficiency through gear wheel 11 being divided into gear wheel axle sleeve part 111; Stepped split faying face 18 is convenient to the assembling of gear wheel axle sleeve part 111 and motivation transfer motion part 112 simultaneously, has strengthened linking steady character.
Because gear wheel 11 integral diameters are bigger; In rotary course, be easy to cause gear wheel 11 to swing up and down; Thereby the stationarity of influence running; Also can lose more kinetic energy; For avoiding this situation to take place, on the gear wheel axle sleeve part lower surface 113 its with anchor ring 114 that bearing upper surface 141 cooperates on along the circumferential direction form a plurality of installation slotted eyes 115, in each installation slotted eye 115 dish spring levitation device 19 is installed; Dish spring levitation device 19 comprises dish spring 191, be positioned at the notch gripper shoe 192 at notch place and be positioned at the bottom land pressure-resistant plate 193 at bottom land place; Dish spring levitation device 19 is through the fastening installation of screw, and screw 6 passes notch gripper shoe 192, dish spring 191 and bottom land pressure-resistant plate 193 successively dish spring levitation device 19 is installed in the installation slotted eye 115, and each notch gripper shoe 192 lower surface is against on the bearing upper surface 141 under the elastic force effect of dish spring 191 on the circumferencial direction; And anchor ring 114 is 1～1.5mm with the vertical range h of bearing upper surface 141, for the suspension effect of dish spring levitation device 19 provides the space.Wherein, notch gripper shoe 192 must have certain rigidity with bottom land pressure-resistant plate 193, makes it play supporting screw 2 respectively and prevents the effect that dish spring 191 damages by pressure.So, in the rotary course of gear wheel 11,, make its running steadily, reduced energy loss because the existence of dish spring 191 has cushioned swinging up and down of gear wheel 11.
For fully playing the seal oil effect; Offer labyrinth type groove 152 on the bearing block upper surface 151; Correspondence is provided with labyrinth type protruding 116 on the gear wheel axle sleeve part lower surface 113; Contact thereby make bearing upper surface 151 cooperate with labyrinth type protruding 116 through labyrinth type groove 152, prevented that effectively lubricating oil from exposing, sealing, high lubricating effect convenient processing and installation with gear wheel axle sleeve part lower surface 113.Its circumferencial direction of 154 upper edges, the face of cylinder, outer ring of bearing block 15 is provided with installs wing limit 153 so that adopt the fastening installation shaft bearing 15 of screw on the wing limit 153 installing, install wing limit 153 can with this body by integral forming of bearing block 15; Simultaneously, for ease of bearing block 15 installing/dismountings, except that part employing and bearing 14 fit dimensions that bearing block 15 contacts with bearing 14, about the external diameter value big 1mm of other discontiguous split bearing seat 15, greatly facilitate the dismounting of bearing block 15 than bearing 14.
Back tightening nut 13 and screw rod 12 threaded engagement, and be fixed with one with gear wheel axle sleeve part 111, play the effect that prevents screw rod 12 random axially-movables; Whether back tightening nut 13 is fastening; Be the key point that guarantees screw rod and electric screw press thrust bearing gap, for guaranteeing the locking of back tightening nut 13, back tightening nut upper surface 131 is provided with the keyway that extends to screw rod upper surface 122; Be provided with locking key 3 in the keyway, and locking key 3 adopts, and screw is fastening to be fixed on the screw rod upper surface 122; In addition; Back tightening nut external cylindrical surface 132 is provided with backstop gap 133; Backstop gap 133 places are fixed with locking block 4, and locking block 4 is fixed on to adjusting screw rod 12 and electric screw press thrust bearing gap through the fastening mode of screw and is arranged on the adjustment gland 5 between back tightening nut 13 and the gear wheel axle sleeve part 111.It is any loosening that these two kinds of anti-loose structure actings in conjunction can guarantee that back tightening nut 13 can not produce.
The above; It only is the preferred embodiment of the utility model; Be not to be the restriction of the utility model being made other form, any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified as the equivalent embodiment of equivalent variations.But every the utility model technical scheme content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of the utility model technical scheme according to the technical spirit of the utility model.
