Abstract
The utility model relates to a sealed locomotive gearbox with head face, a radial static sealing ring and a radial dynamic sealing ring are fixed at the static sealed neckline hole wall and dynamic sealed neckline hole wall of a gearbox respectively, and an axial sealing edge of head face are arranged on the radial static sealing ring and the radial dynamic sealing ring. From the beginning of the seal for the head face of the gearbox, and the axial direction of head face of the gear is considered only, so that the difficulty on assembly can be reduced, thereby the constancy of the sealing face of the entire head face can be ensured, and which is helpful to improve the sealing effect of the gearbox, so the cost of fuel can be reduced; the environmental pollution can be lowered; and the maintenance for the locomotive gearbox can be avoided. A seal is arranged on the head face so as to make the seal become a first checkpoint for solving the oil leakage problem, thereby a small environment with less oil leakage is formed between the seal of head face and the radial seal, the small environment not only can ensure reasonable lubrication of radial seal, but also can avoid the leakage to the outside of the gearbox; furthermore, the structure is reasonable; the utility model can ensure the locomotive to be operated reliably and normally.
Description
Technical field
The utility model relates to a kind of installing locomotive gear cases, belongs to field of mechanical technique.
Background technology
The leakage of oil problem of internal combustion, electric locomotive gear case is the difficult problem that railway locomotive can't fine solution always.The radial seal at the dynamic and static sealing neckline of installing locomotive gear cases place has all only been considered in the sealing of existing installing locomotive gear cases, and starting with from radial seal solves the leakage of oil problem.There is following defective in this means.At first, because the desaxe of gear wheel shaft and gear case sealing eckband, installing locomotive gear cases is to use under high-speed travel state in addition, causes radial seal to be difficult to satisfactorily finish the sealing task.Secondly, gear wheel shaft is adding man-hour, even there is very little screw thread trace on the axial plane, under high-speed condition, also can produces and significantly push away the oil effect, thereby strengthen the leakage of oil problem.Thereby, rely on the leakage of oil problem that radial seal can not solve gear case well merely.
The utility model content
The purpose of this utility model is to provide a kind of installing locomotive gear cases of band edge face sealing, to improve the sealing property of installing locomotive gear cases.
For achieving the above object, the technical solution of the utility model has been to adopt a kind of installing locomotive gear cases of band edge face sealing, is provided with axial end face dynamic seal edge on radially static seal circle fixing respectively on the static seal eckband hole wall of casing and the dynamic seal eckband hole wall and dynamic radial seal circle.
The axial end face dynamic seal that is provided with on the radially static seal circle of fixing on the static seal eckband hole wall of described casing is along being axial straight tube-like edge.
The axial end face dynamic seal that is provided with on the dynamic radial seal circle of fixing on the dynamic seal eckband hole wall of described casing is along the horn-like edge of outwards sticking up for the band footpath.
Owing on radially static seal circle fixing respectively on the static seal eckband hole wall of casing and the dynamic seal eckband hole wall and dynamic radial seal circle, be provided with axial end face dynamic seal edge, make the utility model start with from side seal, only can with the axial location of considering gear face, reduced assembly difficulty, guaranteed the constant character of whole side seal face, help to improve the sealing effectiveness of gear case, both reduced the amount of expending of oil plant, reduced pollution again, also avoided the maintenance capacity of installing locomotive gear cases environment.In addition, after end face is provided with sealing, make side seal become the outpost of the tax office, first road that solves the leakage of oil problem, make and formed a microenvironment that a small amount of oil leak is only arranged between side seal and the radial seal, this microenvironment had both guaranteed leak free reasonable lubrication radially, avoid the seepage outside gear case again, relatively rationally, guaranteed reliable, the normal operation of locomotive on the structure.
Description of drawings
Fig. 1 is the structural representation of the utility model installing locomotive gear cases;
Fig. 2 is the A-A section-drawing among Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, gear case of the present utility model is fastened by upper box 1 and lower box 2 and forms.From outside to inside being provided with three cannelures, setting-in two ring cross-sections are the felt sealing band 4 of rectangle in two outer circular grooves on the hole wall of the dynamic seal eckband 3 of casing; Have stretch to that inboard axial band footpath outwards sticks up horn-like by being embedded with a circle in the belt groove of lining along 6 rubber seal 5.Outwards stick up in the band of rubber seal 5 footpath horn-like upwarp along 6 after, gear 12 outer faces are had elasticity compress and scrape functional oil.In addition, the hole wall of the static seal eckband 8 of casing is provided with two belt grooves, be embedded with a pair of connection rubber seal 9 in two belt grooves, the top of this duplex seal ring 9 is the half-cylindrical sealings of two circles, the bottom is a rectangle setting-in portion, stretch out an axial straight tube-like on the medial surface of this duplex seal ring 9 along 10 hermetically-sealed constructions, straight tube-like presses on gear 12 inner side ends 11 along the direct elasticity of 10 hermetically-sealed constructions, reaches sealing function.
