Abstract
The utility model discloses a cooling drum shaft for a working machine main shaft, wherein bearings are sleeved on the upper and the lower ends of the working machine main shaft, a cooling cylinder shaft which is used to fix a bearing outer ring is arranged between the two bearings, the cooling cylinder shaft comprises a hollow shaft body, ring-shaped grooves which are used to install sealing rings are arranged on the two ends of the outer surface of the hollow shaft body, cooling grooves are spirally arranged on a middle segment of the outer surface of the hollow shaft body, and the sections of the cooling grooves are half spherical shapes. The cooling drum shaft for the working machine main shaft brings away heat which is produced when the bearings work by arranging a spiral groove, and prevents impurities in the air from entering the bearings by arranging the sealing rings on the two ends.
Description
Technical field
The utility model relates to a kind of process equipment, is specifically related to the heat-dissipating cylinder axle that a kind of working machine main shaft is used.
Background technique
The up and down two ends of existing working machine main shaft are set with bearing, be provided with the cylinder axle of fixing described two bearing outer rings between the described upper and lower bearing, this axle is the hollow circuit cylinder axis body, and working machine is when work, the bearing heat dissipating capacity is maximum, and does not have good sink.
The model utility content
The technical problem that (one) will solve
The technical problems to be solved in the utility model provides a kind of radiating structure that has, and guarantees the heat-dissipating cylinder axle that the working machine main shaft in bearing working life is used.
(2) technological scheme
For solving the problems of the technologies described above, the heat-dissipating cylinder axle that the utility model provides a kind of working machine main shaft to use, the upper/lower terminal of working machine main shaft all is set with bearing, heat-dissipating cylinder axle for the rigid bearing outer ring is installed between two bearings, this heat-dissipating cylinder axle comprises hollow shaft, the two ends of hollow shaft outer surface are provided with for the annular groove that seal ring is installed, and the intermediate section spiral of this hollow shaft outer surface is provided with the heat radiation groove.
Wherein, the cross section of this heat radiation groove is semicircle.
(3) beneficial effect
Compared with prior art, the heat that the utility model produces when helical groove is set bearing working is taken away, and is provided with seal ring at two ends, prevents that airborne impurity from entering bearing.
Description of drawings
Fig. 1 is the perspective view of the heat-dissipating cylinder axle used of the utility model working machine main shaft.
Fig. 2 is the Facad structure schematic diagram of the heat-dissipating cylinder axle used of the utility model working machine main shaft.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but can not be used for limiting scope of the present utility model.
The upper/lower terminal of working machine main shaft all is set with bearing, heat-dissipating cylinder axle for the rigid bearing outer ring is installed between two bearings, as shown in Figure 1, this heat-dissipating cylinder axle comprises hollow shaft 1, the two ends of hollow shaft 1 outer surface are provided with for the annular groove 11 that seal ring is installed, the intermediate section spiral of this hollow shaft 1 outer surface is provided with heat radiation groove 12, and the cross section of this heat radiation groove is semicircle, as shown in Figure 2.
During work, air is taken away the heat that bearing working produces by the heat radiation groove, avoids bearing running hot and affects the normal use of bearing, has prolonged the working life of bearing; And the two ends of axis body are provided with the annular groove that seal ring is installed, and avoid airborne impurity to enter bearing and affect the use of bearing.
It below only is preferred implementation of the present utility model; should be pointed out 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 improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
1. heat-dissipating cylinder axle that the working machine main shaft is used, it is characterized in that: the upper/lower terminal of this working machine main shaft all is set with bearing, heat-dissipating cylinder axle for fixing described bearing outer ring is installed between described two bearings, this heat-dissipating cylinder axle comprises hollow shaft (1), the two ends of described hollow shaft (1) outer surface are provided with for the annular groove (11) that seal ring is installed, and the intermediate section spiral of this hollow shaft (1) outer surface is provided with heat radiation groove (12).
