Abstract
The utility model discloses a splash system lubrication reducing gear box, including box (2) and case lid (1) be provided with drive tooth (5), intermediate tooth (4) and differential tooth (3) of meshing in proper order in box (2), its characterized in that: intermediate tooth (4) and lower part between differential tooth (3) is provided with oil baffle (6). Adopt the utility model discloses a splash system lubrication reducing gear box can improve lubricated effect, and reduce cost improves the life -span.
Description
Technical field:
This utility model relates to splash system lubrication reduction box.
Background technology:
Splash system lubrication reduction box in the market, reduction box differential mechanism end die cavity is relatively big, causes fuel consumption big；Its internal each layer gear position is the most wrong, can only lean on due to other axle teeth of differential gear splash lubrication.If injection flow is not enough, will cause countershaft-gear lubrication poor, noise is big, the life-span is short；Particularly shift motor, owing to axle tooth exists relative motion, axle tooth frictional heating in the case of unlubricated expands, it may appear that the phenomenons such as locking, and sends and utter long and high-pitched sounds.If increasing injection flow lubrication countershaft-gear, cost will be caused again to increase, current of electric is big, efficiency is low.
Such as the existing splash system lubrication reduction box in Fig. 1, inject enough lubricating oil, but owing to differential gear is excessive, can only use differential gear splashing to idler gear or start tooth be lubricated, but such mode cannot ensure center tooth or startup tooth are carried out enough lubrications, arises that the defect of above-mentioned poor lubrication when lubricating inadequate；In order to improve lubricant effect can only charging-up lubricant oil, the most also there will be the problems such as above-mentioned middle cost increases and efficiency is low.
Utility model content:
The purpose of this utility model is to provide high lubricating effect and the splash system lubrication reduction box of low cost.
In order to achieve the above object, this utility model is achieved in that a kind of splash system lubrication reduction box, including casing and case lid, driving tooth, center tooth and the differential tooth engaged successively it is provided with in described casing, it is characterised in that: the bottom between described center tooth and described differential tooth is provided with oil baffle.Use above-mentioned set-up mode, bottom between described center tooth and described differential tooth is provided with oil baffle, when motor drives tooth, and then drive center tooth and the work of differential tooth, differential tooth spiral turns, make the lubricating oil splash below differential tooth under the influence of centrifugal force, be expressed to the opposite side of oil baffle, lubricating oil is made to be divided into two-layer, it also is able to be lubricated to center tooth, and idler gear rotates, it also is able to the lubricating oil splash made under the influence of centrifugal force below center tooth, and then to driving tooth to be lubricated, reaches good lubricant effect.And such set-up mode is without increasing charging-up lubricant oil amount so that the cost of lubrication lowers, efficiency is high.
In order to improve lubricant effect further, described center tooth is two or more, and the bottom between adjacent two center tooth is provided with oil baffle.So enable to lubricating oil and be divided into multilamellar, it is possible to each center tooth is the most sufficiently lubricated.
In order to improve lubricant effect further, the bottom between described center tooth and described driving tooth is provided with oil baffle.So enable to lubricating oil and be divided into multilamellar, and sufficiently can lubricate driving tooth,
Preferably, described oil baffle is made up of the baffle plate A being arranged on described case lid and the baffle plate B being arranged on described casing.So make to manufacture and easier for installation.
In order to further facilitate lubricating oil return, between described baffle plate A and described baffle plate B, there is gap.
Preferably, described gap is formed by the paper washer being arranged between described case lid and described casing.Such setting makes processing and manufacturing be more prone to.
Use splash system lubrication reduction box of the present utility model, the beneficial effect that can bring has: 1. enable to lubricating oil and be divided into multilamellar, center tooth and driving tooth are carried out enough lubrications, the problem such as avoid the noise that produces because of lack of lubrication big and the axle tooth life-span is short, it also avoid the phenomenon that the frictional heating between axle tooth expands and locking occurs so that reduction box ensure that normal operating.2. can reduce cost, improve efficiency, it is to avoid the problems such as current of electric is big.
Accompanying drawing illustrates:
Fig. 1 is splash system lubrication reduction box in prior art；
Fig. 2 is the splash system lubrication reduction box in this utility model embodiment；
Fig. 3 is the left view of Fig. 2.
Detailed description of the invention:
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in further detail; but this utility model is not limited to these embodiments; any improvement on the present embodiment essence spirit or replacement, still fall within this utility model claim scope required for protection.
Embodiment:As shown in Figures 2 and 3, a kind of splash system lubrication reduction box, including casing 2 and case lid 1, in described casing, it is provided with driving tooth 5, center tooth 4 and the differential tooth 3 engaged successively, the bottom between described center tooth 5 and described differential tooth 3 is provided with oil baffle 6.
Described oil baffle 6 is made up of the baffle plate A61 being arranged on described case lid 1 and the baffle plate B62 being arranged on described casing 2.Wherein said baffle plate A61 and described case lid 1 can be set to one in casting process, and described casing 2 and described baffle plate B62 can also be set to one in casting process.
It is provided with paper washer 7 between described case lid 1 and the mould assembling face of described casing 2, paper washer 7 can play the effect to seal oil, and owing to there is paper washer 7, make to there is gap 8 between baffle plate A61 and described baffle plate B62, the size in this gap 8 is the thickness of paper washer 7, (about about 0.4mm).
Work when, lubricating oil is injected in described reduction box, described lubricating oil level is in differential tooth 3 bottom, consistent with in Fig. 1 by the amount of lubricating oil in Fig. 2, then driven by motor is driven to drive tooth 5, tooth 5 is driven to drive center tooth 4, center tooth 4 drives differential tooth 3 again, differential tooth 3 rotates, lubricating oil below differential tooth 3 is splashed, it is expressed to the opposite side of described oil baffle 6, owing to the gap 7 between baffle plate A and baffle plate B is the least, so oil film can be formed between baffle plate A61 and baffle plate B62, lubricating oil can not reflux immediately, and will store, now center tooth 4 will be dipped in fluid, other axle teeth are being lubricated by effects such as splashings.Thus reach not only to save lubricating oil but also can the purpose of extending shaft tooth physical life.
If it addition, center tooth 4 is multiple, it is also possible to the bottom between adjacent two center tooth 4 is provided with oil baffle 6, and/or the bottom between described center tooth 4 and described driving tooth 5 is provided with oil baffle 6.So enable to lubricating oil and be divided into multilamellar, the axle tooth of every one-level can be carried out effect and preferably lubricate.
Finally, idle time, lubricating oil can be refluxed by the gap 8 between oil baffle, it is possible to convenient needs more oil change when.
Use the splash system lubrication reduction box of the present embodiment, first can improve lubricant effect, it is ensured that every primary axis tooth can sufficiently be lubricated, it is to avoid the noise big life-span occurred because lubricant effect is bad is short or the problem such as locking；And the reduction box of the present embodiment also has the advantages such as saving lubricating oil, low cost, efficiency height.
