Abstract
The utility model provides a motor output shaft structure of a shield machine, which is capable to overcoming the defects of installation interference and insufficient guarantee of positioning caused by the factor that manufacturers of a motor output shaft and a reduction gearbox input shaft are different, and avoiding hidden danger to the performance and quality of equipment. The motor output shaft structure of the shield machine comprises a motor output shaft the shaft end of which is provided with a spline shaft. The motor output shaft structure of the shield machine is characterized in that the shaft end of the spline shaft is equipped with a counterbore.
Description
Technical field
The utility model relates to the shield machine motor shaft, is specially a kind of shield machine motor output shaft structure.
Background technique
Shield machine is as a kind of large tunnel development machine of special use, and its assembly structure that comprises is very many, and is for guaranteeing the overall performance of equipment, very high to assembly technical requirement.At present, just wherein there is such present situation in the assembling of shield machine motor and speed reducer: existing assembling is that the shaft hole inner wall spline of motor output shaft and the keyway of reduction box input shaft outer wall are assembled together by closely cooperating of key, groove, but, often to enter the manufacturer of axle different due to motor output shaft and speed reduction box shaft, interfere in the time of can causing installing, assembling and positioning can not get abundant assurance, and this Performance and quality to equipment brings hidden danger.
Summary of the invention
For above-mentioned situation, the utility model provides a kind of shield machine motor output shaft structure, can overcome that to enter the manufacturer of axle different because of motor output shaft and speed reduction box shaft, interfere during the installation that causes, assembling and positioning can not get the defective that fully guarantees, has avoided the hidden danger that equipment performance and quality are brought.
Its technological scheme is such, and it comprises motor output shaft, and the axle head of described motor output shaft is splined shaft, it is characterized in that: the axle head of described splined shaft is provided with counterbore.
It is further characterized in that: the outlet port of described counterbore is provided with chamfering.
After the utility model adopts said structure, when shield machine motor output shaft and reduction box input shaft assembling, reduction box input shaft first passes through counterbore, follow again the spline fitted with motor output shaft, counterbore has just played the effect of transition, adjustment and an axially locating like this, if motor output shaft comes from different manufacturers from reduction box input shaft, shield machine motor output shaft structure so of the present utility model, interference and the assembling and positioning that just can solve well when installing can not get the fully technical problem of assurance.
Description of drawings
Fig. 1, existing shield machine motor output shaft structural representation;
Fig. 2, structural representation of the present utility model.
Embodiment
See Fig. 2, the utility model motor output shaft 1, the axle head of motor output shaft 1 are splined shaft 2, and the axle head of splined shaft 2 is provided with counterbore 3, and the outlet port of counterbore 3 is provided with chamfering 4.When shield machine motor output shaft and reduction box input shaft assembling, the reduction box input shaft end is first stretched in counterbore 3, then coordinate with splined shaft 2 again, counterbore 3 has played good transition, adjustment and axially locating effect in assembly process, the design of the outlet port chamfering 4 of counterbore 3 makes the diaxon assembling convenient.
Claims (2)
