The Self-lubricating gear speed change gear
The utility model belongs to machinery manufacturing technology field, relates in particular to a kind of Self-lubricating gear speed change gear.
Be provided with at least two transmission shafts in the gearbox, the transmission shaft two ends are automatically connected on the gearbox by bearing rotary, gear is installed on the transmission shaft, the bottom of gearbox is loaded with lubricant oil, the gear bottom is immersed in the lubricant oil, and along with the rotation of gear, gear upwards is thrown to lubricant oil on the inwall of gearbox, lubricant oil flows down along the gearbox inwall, thereby is lubricated for bearing.This lubricating system is applicable to the gear of High Rotation Speed, for the gear of low speed rotation, because gear rotational speed is lower, and high the throwing away that lubricant oil can not be made progress, this just greatly has influence on the lubricated of bearing, and in the course of time, bearing just is easy to damage.
The model utility content
The utility model is in order to solve deficiency of the prior art, a kind of high lubricating effect is provided, is specially adapted to the Self-lubricating gear speed change gear of gear low speed rotation.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: the Self-lubricating gear speed change gear, comprise casing, be rotatably connected at least two transmission shaft in the casing, transmission shaft is automatically connected on the casing by bearing rotary, and transmission shaft is provided with gear, bottom half is loaded with lubricant oil, described gear sidepiece is provided with at least one and ladles out oil skipper, when ladle out oil skipper along with gear turn to bottom the time, ladle out oil skipper and be immersed in the lubricant oil.
The described oil skipper of ladling out is evenly arranged 3-6 along Gear center.
Described cabinet wall is provided with the oil guide slot for lubricating bearings.
Adopt technique scheme, transmission shaft driven gear and ladle out oil skipper and rotate turns to lubricant oil liquid level lower time when ladling out oil skipper, ladles out oil skipper lubricant oil has been ladled out, when upwards rotating lubricant oil is thrown away or fall down, lubricant oil just can flow down by the oil guide slot lubricating bearings along cabinet wall.
The utility model is reasonable in design, simple in structure, high lubricating effect, and all parts in the casing is played good lubrication, is specially adapted to the speed change gear of gear low speed rotation, fully prolongs the working life of the parts such as bearing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
As shown in Figure 1, Self-lubricating gear speed change gear of the present utility model, comprise casing 1, be rotatably connected in the casing 1 among at least two the transmission shaft 2(figure and only illustrate a transmission shaft 2), transmission shaft 2 is rotatably connected on the casing 1 by bearing 3, and transmission shaft 2 is provided with gear 4, casing 1 bottom is loaded with lubricant oil 7, gear 4 sidepieces are provided with at least one and ladle out oil skipper 5, when ladle out oil skipper 5 along with gear 4 turn to bottom the time, ladle out oil skipper 5 and be immersed in the lubricant oil 7.Ladle out oil skipper 5 and be evenly arranged 3-6 along gear 4 centers.Casing 1 inwall is provided with the oil guide slot 6 for lubricating bearings 3.
When the utility model uses in work, transmission shaft 2 driven gears 4 and ladle out oil skipper 5 and rotate, turn to 7 liquid level lower times of lubricant oil when ladling out oil skipper 5, ladling out oil skipper 5 has ladled out lubricant oil 7, when upwards rotating lubricant oil 7 is thrown away or fall down, lubricant oil 7 just can flow down by oil guide slot 6 lubricating bearings 3 along casing 1 inwall.
