Abstract
The utility model relates to a gearbox, particularly a geared box which is mainly formed by that a circulating hole which is communicated with a containing chamber and an empty slot is arranged on the wall of an upper bearing base; a machine cover is provided with an air leaking hole; the circulating hole is a sloped passage, consequently extending the service life of workpieces in the box body, and engine oil is not easy to be leaked.
Description
The utility model relates to a kind of fast case, especially refers to speed-changing gear box.
At present, the gearbox of weight industrial machine or speed reducer, its casing all forms confined space, and do not have ventilation space, as shown in Figure 1, by cabinet A by having a dead slot D in conjunction with forming behind upper bearing (metal) B and the footstock C, and make cabinet A cause the trough E of confined space, though therefore cause the lubricated cooling of the parts F organic oil (gear oil) in the cabinet A, but,, and make parts when permanent transmission because to be the full closed space airtight, make the cabinet inner engine oil produce high temperature, and not only easily make machine oil rotten under the high temperature, easier each parts that cause destroy material morphological element because of being in for a long time under the high temperature, shorten the life-span of parts, moreover the gap F2 of machine oil The book of Changes screw rod F1 of high temperature and dead slot D leaks the destruction drive motor.
In view of this, the purpose of this utility model provides a kind of gearbox of improvement, but the machine oil automatic cycle in cabinet, and be to flow into again in the machine trough after entering dead slot, motor-driven temperature is descended.
The purpose of this utility model is achieved in that a kind of gearbox of improvement comprises cabinet, driven member, driving link, upper and lower bearing, lid, upper bearing bracket, dead slot, room, space, trough and cover, it is characterized in that: on the upper bearing bracket wall, be provided with the circulation port that is communicated with room and dead slot, also offer bleeder port on the cover.
Described circulation port is into oblique passage.
Owing to adopt such scheme: prolong the working life of parts in the casing, and machine oil is difficult for also leaking.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the cross-sectional schematic of the utility model exemplary embodiments;
Fig. 2 is the part section stereogram of the utility model exemplary embodiments;
Among the figure: 1. cabinet 2. driven members 3. driving links 4. upper bearing (metal)s 5. lower bearings 6. lids 7. upper bearing brackets 8. circulation ports 9. dead slots 10. rooms 11. spaces 12. altitude lines, 13. troughs, 14. covers, 140. bleeder ports
As shown in Figure 2, the roughly the same compositions such as cabinet 1, driven member 2, driving link 3, upper and lower bearing 4,5 and lid 6 that comprise of present embodiment with known techniques, wherein the wall of the appropriate location, upper bearing bracket 7 top of the driving link 3 of cabinet 1 is provided with the circulation port 8 of machine oil, for the machine oil in the dead slot 9 that circulation port 8 is had release, be into oblique be set to good, the room 10 that the circulation port 8 that makes machine oil of taking second place can be from the dead slots 9 that produced in conjunction with upper bearing (metal) 4 back through cabinet 1; The aperture of this circulation port 8 system can decide according to different type of machines again, and it is with one or more circulation port 8 that its number is, therefore, after being injected into suitable machine oil in the room 10 of cabinet 1, when driven member 2 produces running with driving link 3, machine oil in the room 10 both can produce lubricated cooling to driven member 2 at once, and the general altitude line 12 that all injects of the machine oil in trough 13, so far, when driving link 3 and driven member 2 drive running by motor, oil can enter in the dead slot 9 through upper bearing (metal) 4, and the machine oil in the dead slot 9 flows in the room 10 through circulation port 8 again, to form circulation, and can be 11 do not leak from the space, can avoid befouling environment and lower motor life, and machine oil also can be because of driven member 2, the exhaust gas temperature that the running of driving link 3 grades produces, the air that utilizes the bleeder port 140 of cover 14 to introduce in the outside normal temperature because of the circulation of machine oil, make cabinet 1 interior hot gas at once behind dead slot 9, discharge in space 11 by driving link 3 axles and lid 6, the room 10 interior air-flows that reach cabinet 1 can produce convection current rapidly, reach Rapid Cycle, make that temperature can be too not high in the cabinet 1, keep the low temperature of machine oil and never degenerate, the parts in the cabinet can prolong working life greatly simultaneously.
Claims (2)
1, a kind of gearbox of improvement comprises cabinet (1), driven member (2), driving link (3), upper and lower bearing (4), (5), lid (6), upper bearing bracket (7), dead slot (9), room (10), space (11), trough (13) and cover (14), it is characterized in that: on upper bearing bracket (7) wall, be provided with the circulation port (8) that is communicated with room (10) and dead slot (9), also offer bleeder port (140) on the cover (14).
2, by the described gearbox of claim 1, it is characterized in that: described circulation port (8) is into oblique passage.
