Description
Technical field
The utility model relates to the technical field of high-speed railway device, especially a kind of Novel gearbox used for high-speed railway.
Background technique
In recent years, along with socioeconomic fast development, high-speed railway traffic being had higher requirement, in order to adapt to the continuous speed-raising of high-speed railway under the new situation, also the device on high-speed railway being had higher requirement in technical requirements.
Gear-box is the important device for lifting speed in high-speed railway, the requirement of its property indices is all very strict, existing most electric motor end cap comes with some shortcomings part in structural design: as, gear-box is made of cast iron usually, and its tensile strength and shock strength all not easily reach the technical requirements of high-speed railway to device; In order to meet working strength, therefore gear-box lacking a large amount of radiation holes, after gear-box long-time running, gear-box can produce a large amount of heats and can not distribute timely, easily causing gear-box to occur phenomenon of rupture; Meanwhile, in order to meet working strength, the tank wall of gear-box is usually thicker, and entirety is comparatively heavy; Above-mentioned defect makes these gear-boxes all can not meet light, fast, the steady requirement of high-speed railway.
Model utility content
The technical problems to be solved in the utility model is: in order to solve the problem proposed in above-mentioned background technology, and the utility model provides the Novel gearbox used for high-speed railway that a kind of thermal diffusivity is good, quality light, tension shock strength is high.
The utility model solves the technological scheme that its technical problem adopts: a kind of Novel gearbox used for high-speed railway, have and to be made up of aluminum alloy and casing in spiral case thin wall shape, the upper box lid that described casing comprises lower block and matches with it, the upper mating face of described lower block and the inclined-plane of lower mating face all in right low left high of upper box lid; The middle position of lower block and upper box lid is processed with the spindle mounting hole for installing main shaft jointly, upper box lid offers and to be positioned on the right side of spindle mounting hole and transmission shaft mounting hole for installing transmission shaft, casing is evenly provided with some stiffening ribs radially.
Upper box lid described in technique scheme offers the oil hole for injecting lubricant oil in transmission shaft mounting hole.
Circumferentially several positioning holes are evenly offered along transmission shaft mounting hole on upper box lid described in technique scheme.
The joint of lower block and upper box lid described in technique scheme is evenly provided with several and strengthens contiguous block.
The beneficial effects of the utility model are: Novel gearbox used for high-speed railway of the present utility model has following positive advantage:
(1) whole casing is made up of aluminum alloy, and quality is light, and plasticity is good, and be easy to processing, tensile strength and shock strength all can meet the technical requirements of high-speed railway to device;
(2) wall thickness of whole casing is thinner, causes its radiating effect better; Meanwhile, it is also made to have good contractive effect;
(3) whole casing is arranged some stiffening ribs radially, ensure that its working strength;
(4) whole casing is assembled by lower block and upper box lid, and the inclined-plane of lower mating face all in right low left high of the upper mating face of lower block and upper box lid, cause the easier for installation of whole casing, make the floor space of whole casing less simultaneously;
(5) structural design of whole casing is very reasonable, meets the requirement that high-speed railway is light, fast, steady completely, can be widely used on high-speed railway.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is front view of the present utility model;
