Abstract
The utility model discloses a box of a speed reducer. The box of the speed reducer comprises a shell of the speed reducer and a bearing which is arranged in the shell, wherein an oil guide groove is formed between the inner side of the shell of the speed reducer and the bearing; and one end of the oil guide groove is fixed on the inner wall of the shell of the speed reducer, and the other end of the oil guide groove extends to an end face of the bearing. The box of the speed reducer has the characteristics of ideal lubricating effect of the bearing, low consumption of lubricating oil, reasonable structure, low manufacturing cost, and the like.
Description
Technical field
The utility model relates to retarder, is specifically related to a kind of bearing lubrication reduction case satisfactory for result.
Background technique
As everyone knows; Bearing lubrication above being positioned in the reducer gear transmission device; Generally be to lean on splash lubrication, but because the particularity of structure, often rely on the high-speed gear rotation and got rid of to the lubricant oil of cabinet wall and be difficult to flow to or drip bearing; The intensification of bearing can be caused like this, the damage of bearing can be caused behind the long-play.
The model utility content
That the purpose of the utility model is is big to undesirable, the lubricant oil consumption of existing in prior technology bearing lubrication effect, the technical problem of complex structure etc., provides that a kind of bearing lubrication is satisfactory for result, the lubricant oil consumption is saved, the deceleration box that is provided with the Oil Guide ditch rational in infrastructure.
For realizing above-mentioned purpose; The technological scheme of the utility model is a kind of reduction case of design; The bearing that comprises reducer shell and be arranged on enclosure interior is characterized in that, between said reducer shell inboard and bearing, has set up the Oil Guide ditch; Said Oil Guide ditch one end is fixed on the speed reducer inner walls, and the Oil Guide ditch the other end ends at the end face of bearing.Set up between speed reducer housing inboard and the bearing as if bar Oil Guide ditch, it promptly can put together the lubricant oil that takes up along the circumference of gear velocity attitude, and also can import lubricant oil needs lubricated bearing: can play good lubricating effect.
Wherein optimized technical scheme is, described Oil Guide ditch is at least one, and described Oil Guide ditch is by level or be obliquely installed on the inwall of housing.
Further optimized technical scheme is, described Oil Guide ditch is a groove shape structure, and its cross section is " recessed " font.Can dispose difform Oil Guide ditch according to the different size and the needs of gearbox casing.
Further optimized technical scheme also has, and described Oil Guide ditch and casing cast inblock form.It is rational in infrastructure, and manufacture cost is cheap relatively.
Further optimized technical scheme also has, and described Oil Guide ditch is embedded on the inwall of housing.
The advantage and the beneficial effect of the utility model are: this reduction case has that bearing lubrication is satisfactory for result, the lubricant oil consumption is saved, rational in infrastructure, characteristics such as manufacture cost is cheap relatively.
Description of drawings
Fig. 1 is the structure sectional view of the utility model reduction case.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technological scheme of the utility model, and can not limit the protection domain of the utility model with this.
As shown in Figure 1; The utility model is a kind of reduction case, and the bearing 2 that comprises reducer shell 1 and be arranged on enclosure interior has set up two Oil Guide ditches 3 between reducer shell inboard and the bearing; Oil Guide ditch and casing are an integral body, and an end ends near bearing face.The Oil Guide ditch is a groove shape structure, and its cross section is " recessed " font.Oil Guide ditch and casing cast inblock form.
When installing and using, rely on and be located at the Oil Guide ditch between speed reducer housing inboard and the bearing, promptly can put together the lubricant oil that takes up along the circumference of gear velocity attitude, and import the bearing that need lubricate to lubricant oil, can play good lubricating effect.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
Claims (5)
1. reduction case; The bearing that comprises reducer shell and be arranged on enclosure interior is characterized in that, between said reducer shell inboard and bearing, has set up the Oil Guide ditch; Said Oil Guide ditch one end is fixed on the speed reducer inner walls, and the Oil Guide ditch the other end ends at the end face of bearing.
2. reduction case as claimed in claim 1 is characterized in that, described Oil Guide ditch is at least one, and described Oil Guide ditch is by level or be obliquely installed on the inwall of housing.
