Abstract
The utility model relates to a matching structure of a motor output shaft gear and a tower type gear box central output shaft gear, which comprises the motor output shaft gear and the tower type gear box central output shaft gear which is coaxial with the motor output shaft gear. The tower type gear box central output shaft gear is provided with a bearing chamber which is coaxial with the tower type gear box central output shaft gear, the bearing chamber is provided with a bearing in matched mode, an extending end which is coaxial with the motor output shaft gear is arranged at the end of the motor output shaft gear, and the extending end is matched with a bearing inner ring. The matching structure solves the problems in the prior art that a motor and a tower type gear box are too large in mechanical vibration, easy to damage and the like.
Description
Technical field
The utility model relates to the fit structure that a kind of Motor Shaft gear and cluster gear case center go out shaft gear, belongs to the technical field of gearing.
Background technology
Motor can be converted into mechanical energy to electric energy, but in the process of motor operation, rotating speed of motor, transmission direction is fixed.In order to regulate rotating speed of motor, transmission direction, can use the cluster gear case to come to cooperate to reach adjusting rotating speed and transmission direction with motor.In the prior art, the end that Motor Shaft gear and cluster gear case center go out shaft gear all is unsettled, does not have supporter support.Two gears that do not support setting make machinery in running, become very unstable, have increased the mechanical failure and the excessive possibility of Oscillation Amplitude of motor and cluster gear case.
Summary of the invention
The utility model purpose is to provide a kind of Motor Shaft gear and cluster gear case center to go out the fit structure of shaft gear, and the motor and the vibration of cluster gear punch-out equipment tool that have solved the prior art existence are excessive, problems such as easy damage.
The above-mentioned technical purpose of the utility model mainly solves through following technical scheme: it comprises the Motor Shaft gear and goes out shaft gear with the coaxial cluster gear case center of Motor Shaft gear; Cluster gear case center goes out shaft gear and is provided with a bearing chamber; It is coaxial that bearing chamber and cluster gear case center go out shaft gear; Bearing chamber is equipped with a bearing, and the end of Motor Shaft gear is provided with an elongated end coaxial with the Motor Shaft gear, and elongated end and bearing inner race match.
Through the improvement of utility model, the end of Motor Shaft gear has been inserted into and has been fixed on cluster gear case center and goes out in the bearing in the shaft gear.When opening motor, because the effect of bearing is arranged, Motor Shaft gear and cluster gear case center go out shaft gear can carry out rotation separately, between the two not influence.The while bearing goes out shaft gear by the Motor Shaft gear with cluster gear case center and is connected, and makes both all not unsettled.Do not have unsettled structure, reduced the offset that in rotation process, brings at both, thereby it is excessive to have solved when motor and cluster gear case cooperate in the prior art mechanical oscillation, the problem that parts damage easily.
As preferably, the bearing chamber bottom is provided with one and supports annulus, supports annulus and offsets with the bearing outer ring end face, and the internal diameter of support annulus is more than or equal to the internal diameter of bearing outer ring.Through the setting of preferred structure, bearing has only the outer ring to contact with the bearing chamber bottom, makes friction when whole bearing has reduced the inner ring rotation in rotation process.
As preferably, bearing is positioned at cluster gear case center shaft gear shaft to the middle position.Bearing is positioned at cluster gear case center shaft gear shaft and can rotates more steady so that cluster gear case center shaft gear when rotating, is centered close to geometric center to the center.
As preferably, bearing chamber import department is provided with a tapered opening.A tapered opening is set, can be so that after Motor Shaft gear elongated end be inserted into bearing, the Motor Shaft gear is not easy in rotation process and bearing chamber produces collision.
Therefore, the utlity model has simple in structurely, effectively solve motor and cooperate the too much vibration that produces with gear box, machinery is characteristics such as damage easily.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment 1: like Fig. 1, rotor axis of electric 7 drives Motor Shaft gear 5 and rotates through shaft coupling 9, shaft coupling axle sleeve 10.Comprise Motor Shaft gear 5 and go out shaft gear 4 from the utility model with Motor Shaft gear 5 coaxial cluster gear case centers; Being positioned at the gear box center goes out bearing chamber 8 and cluster gear case center on the shaft gear to go out shaft gear 4 coaxial and axially placed in the middle; Bearing chamber 8 is fitted with bearing 1, and the support annulus 3 and the bearing outer ring end face of bearing chamber 8 bottoms offsets and support the internal diameter of the internal diameter of annulus 3 more than or equal to bearing 1 outer ring.The elongated end 2 and bearing 1 inner ring of the end of Motor Shaft gear 5 matches and is inserted in the inner ring.Bearing chamber 8 import departments go out shaft gear 4 generation frictions and are provided with a tapered opening 6 for fear of Motor Shaft gear 5 and cluster gear case center.
In the running of reality, through the design of the utility model, the Motor Shaft gear need not unsettledly be provided with.It and cluster gear case center go out shaft gear and have obtained support mutually, have guaranteed motor and gear box stablizing in transmission process.
