Accompanying drawing explanation
Fig. 1 is the structural representation of existing gear axial positioning structure;
Fig. 2 is structural representation of the present utility model.
Wherein, 1 is that the first gear, 2 is that spline pad, 3 is that the second gear, 4 is that spacer, 5 is that two axles, 6 are that hex key, 7 is that snap ring, 8 is that the first synchronizer, 9 is the second synchronizer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to figure 2, gear axial positioning structure described in the utility model comprises two axles 5, the first gear 1, the second gear 3, is socketed on spacer 4 and the spline pad 2 on two axles 5 and is arranged on respectively the first synchronizer 8 and second synchronizer 9 at two axle 5 two ends; The first gear 1 is placed in a side of two axles 5, the opposite side of two axles 5 is provided with step, one side of spacer 4 is by described step axially locating, the opposite side of spacer 4 is that a side of spline pad 2 is carried out axially locating, the opposite side of spline pad 2 carries out axially locating by the snap ring 7 being socketed on two axles 5, the second gear 3 is placed on spacer 4, and axially locating is carried out by spline pad 2 and spacer 4 respectively in the both sides of the second gear 3; Spline pad 2 is provided with internal spline, two axles 5 are provided with external splines, spline pad 2 is meshed and circumferentially locates with the external splines of two axles 5 by internal spline, is connected between spline pad 2 and two axles 5 by hex key 6 simultaneously, and spacer 4 is provided with the internal spline matching with the external splines on two axles 5.The internal spline of spline pad 2 lacks a tooth, Spielpassung between the second gear 3 and spacer 4.On two axles 5, offer circular groove, described snap ring 7 is embedded in described circular groove.
Described the first synchronizer 8 and the first gear 1 are positioned at a side of spline pad 2, and the second synchronizer 9 and the second gear 3 are positioned at the opposite side of spline pad 2.When described spline pad 2 is subject to the axial force to the second synchronizer 9 one sides, spline pad 2 compresses spacer 4, gapped between spline pad 2 and the second gear 3; When spline pad 2 is subject to the axial force to the first synchronizer 8 one sides, spline pad 2 compresses snap ring 7, gapped between spline pad 2 and the first gear 1.
When the first synchronizer 8 is put into gear to the right, the first gear 1 works, take left-handed as example explanation, the first gear 1 is subject to axial force to the right, the first gear 1 is pushed down spline pad 2, spline pad 2 is pressed on the step of spacer 4, guarantee the design gaps of the second gear 3 between spline pad 2 and spacer 4, thereby make the first gear 1, spline pad 2, spacer 4 and two axle 5 rotating speeds identical, between the first gear 1 and spline pad 2 and relative static between spline pad 2 and spacer 4, not friction, spline pad 2 lifting surface areas are the area of the right side of spacer 4; When states such as vehicle descendings, when engine braking forms counter dragging, the second gear 3 is left stressed, and when now synchronous the second device is hung left, the second gear 3 compresses spline pad 2, and spline pad 2 compresses snap ring 7, guarantees the design gaps between spline pad 2 and gear.If the first gear 1 and the second gear 3 are dextrorotation, stressed opposite direction, can guarantee the design gaps between inoperative gear and spline pad 2 under several working staties equally, guarantees that speed changer normally works.
