Housing lid arranges the opening being used for enclosing housing upper-part 1, and this opening is surrounded by frame-like carrying section, surrounds especially spaced at a distance.This means, the carrying section of frame-like is not directly contact described opening, but separated by a distance with opening.
As shown in Figure 10, gear 100 and axle 101 are can not mode be connected in relative rotation, and described axle 101 is bearing in housing by bearing.At this, this bearing is received in the bearing receiving portion of housing, and wherein, the first portion of bearing receiving portion is arranged in upper case part 1, and the second portion of bearing receiving portion is arranged in lower case part 2.
Lower space region around gear 100 is surrounded by food tray, and described food tray has sidewall 102 and base plate 103.Therefore this food tray can be made up of three workpiece.
At this, the sidewall 102 of food tray is fixed on base plate 103.Base plate 103 has the valgus 130 pointed to downwards in its darkest region.Described valgus 130 is radially pointed to away from gear and is designed at the end regions place that it is positioned at radial outside to open wide.Therefore, the lubricant oil of retarder arrives gear 100 from the oil sump of retarder by valgus 130.The corresponding connecting sheet section 120 of valgus in side, namely in axial both sides by sidewall 102 is closed, thus is formed radially one through to the passage of gear 100.
As shown in figure 12, sidewall 102 respectively punching be plate and axially outside there is mark, shown mark represents the position needing to offer perforation, and this especially depends on the velocity ratio of retarder and/or the engagement data of gear 100.
The threaded piece that can realize being threaded between base plate 103 and each sidewall 102 is guided through perforation.
Therefore, can according to size or other engagement data by backplane on the radial distance from gear medial axis the best.
Base plate 103 is fabricated to equally and rushes comer pieces and have U-shaped cross-section.Be designed to arc like this at this base plate, make the engaging piece of engaging piece, especially gear 100 and base plate 103 spacing be between the top of the tooth in same circumference angle and base plate be constant.Namely between these tooth tops and base plate 103, be provided with narrow slit.
Therefore, pump action is produced when gear 100 rotates, this is because the lubricant oil be in slot is faster than the speed of the lubricant movement in passage.Lubricant oil is made to be delivered to gear 100 by described passage from oil sump and to be moved by this gear driven in this way.
Food tray also reduces the splash loss when gear 100 moves.Because carry out in the area of space that being immersed in of the tooth of the engaging piece of gear 100 is surrounded by food tray.
Except connecting sheet section 120 and valgus 130, the base plate 103 of U-bend song circle (arc) shape ground circumferentially bends, and the spacing between the base plate 103 therefore within the scope of the tooth of the engaging piece of gear 100 and corresponding angle of circumference is constant substantially.
Connecting sheet section 120 points to radially outwardly, and therefore each sidewall 102 can compress vertically or be threaded on base plate 103, especially compresses at its connecting sheet section 120 place or is threaded on base plate 103.
By the pump action that gear 100 and food tray acting in conjunction are formed, oil pump to be delivered on the position higher than the oil level of oil sump and from this by intermediate store or directly guide to position to be lubricated, as bearing or the engaging piece that is in jointing state.Be provided with corresponding pipeline or pipeline for this reason.
Valgus 130 out can manufacture by the bent outward from base plate 103 prototype.For this reason, a bending like this punching plate, makes the region of two bow actions be spaced from each other by the region that a substantial rectangular is bending.After this region of bow action compressed mutually and form circle (arc) the shape region of base plate 103 thus.At this, the region of these two bow actions surrounds a recess.The region of rectangular bend has a recess arranged between two parties equally and therefore forms valgus 130.
