Reference character: idle gear body (1), lightening hole (2), circular groove (3), trapezoidal drain pan (4), gear hub (5), idle gear axis hole (6), idle gear baffle plate (7), idle gear lining (8), idle gear shaft (9), draft angle (Q1), installation angle of deflection (Q2), trapezoidal drain pan angle (Q3), the trapezoidal drain pan degree of depth (h).
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Embodiment 1, and because idle gear adopts overall structure, profile is heavy, and consumptive material is more, and due to weight comparatively large, the power loss of train of gearings can be increased.Gear hub both ends of the surface keep certain axial clearance with idle gear baffle plate and idle gear shaft, for avoid idle gear stuck and formed oil circuit, ensure lubricating end surface.Face yellowing phenomenon is often come in contact in actual use, analysis reason is surface of contact is the kinematic pair run up, very easily produce high temperature, as fuel feeding is not smooth, just cause the yellowing phenomenon that insufficient lubrication causes, even cause kinematic pair inordinate wear, idle gear axial float strengthens or end face injustice causes idle gear unbalance stress, finally causes the catastrophe failures such as gear avalanche.Therefore, devise idle gear body (1) web two ends and arrange circular groove (3), be arranged on idle gear body circumferencial direction, web is connected with the transition of tooth root orthodrome.Idle gear body (1) web arranges lightening hole (2), for asymmetrical design and quantity is odd number.Trapezoidal drain pan (4) is offered at gear hub (5) two ends, each end face has the 4 mutually perpendicular trapezoidal drain pans (4) in road, the trapezoidal drain pan degree of depth (h) is 0.5 ~ 1mm, and trapezoidal drain pan angle (Q3) is 90 ° ~ 120 °.
Embodiment 2, and idle gear body (1) web two ends arrange circular groove (3), and web is connected with the transition of tooth root orthodrome; Trapezoidal drain pan (4) is offered at gear hub (5) two ends, and the trapezoidal drain pan degree of depth (h) is 0.5 ~ 1mm, and trapezoidal drain pan angle (Q3) is 90 ° ~ 120 °; Gear hub (5) and gear web joint have draft angle (Q1) to be 3 ° ~ 5 °; Idle gear axis hole (6) two ends have installation angle of deflection (Q2) to be 15 ° ~ 30 °.
Described circular groove (3), is arranged on idle gear body circumferencial direction, and web is connected with the transition of tooth root orthodrome, greatly reduces idle gear weight, ensures the stability of idle gear at transmission process simultaneously.
Described lightening hole (2), for asymmetrical design and quantity is odd number, effectively weakens the noise that gear produces because of resonance.Lightening hole diameter is large as far as possible under guarantee dedendum strength prerequisite, and gear weight is reduced, and ensures that gear loading is little, smooth running.
Described trapezoidal drain pan (4), be opened in gear hub both ends of the surface, each end face has the 4 mutually perpendicular trapezoidal drain pans (4) in road, the trapezoidal drain pan degree of depth (h) is 0.5 ~ 1mm, trapezoidal drain pan angle (Q3) is 90 ° ~ 120 °, form effective lubricating loop together with idle gear axial clearance, ensure the lubrication that gear face is good.
It is 3 ° ~ 5 ° that described gear hub (5) and gear web joint are provided with draft angle (Q1), improves gear hub rigidity, because strength deficiency easily produces distortion when avoiding processing idle gear axis hole.Arrange draft angle (Q1) can conveniently forge simultaneously.
Described idle gear axis hole (6) two ends have installation angle of deflection (Q2) to be 15 ° ~ 30 °, effectively lead, avoid the trimming of idle gear lining, scrape burr etc. when conveniently press-fiting idle gear lining.
