The output shaft assembling structure comprises an output shaft and a gear which is connected on the shaft neck of an output shaft by keys; bearing are respectively sheathed at both ends of the output shaft; the end surface of one end of the bearing at one end is in contact with the end surface of one end of the gear; the other end surface of the gear at one end is in contact with the shaft shoulder of the output shaft; the end surface of one side of the bearing at the other end close to the shaft body of the output shaft is in contact with the shaft shoulder of the output shaft; transparent covers are respectively pressed on the end surfaces of the other sides of the bearings at both ends; and the transparent covers are respectively connected with a tank body. The output shaft assembling structure is characterized in that double sealing rings are arranged at coordinating parts of the transparent covers and the output shaft.
Description
Technical field
the present invention relates to the speed reducer field, especially a kind of straightening machine speed reducer output shaft assembly structure.
Background technique
speed reducer is that a kind of power is passed on mechanism, utilizes the velocity transducer of gear, the winding number of power source is decelerated to desired winding number, and obtain the mechanism of big torque.Be used for the mechanism of transferring power and motion at present, the application area of speed reducer is quite extensive.Almost in the transmission system of various machinery, can see its trace, from boats and ships, automobile, the locomotive of the traffic tool, heavy facility for building; Machining machine and tool that mechanical industry is used and automated production equipment, common household electrical appliances in the daily life, clock and watch or the like. it uses the transmission work from big power; To little load; Accurate angle transmission can be seen the application of speed reducer, and on commercial Application, speed reducer has deceleration and increases the torque function.Therefore be widely used in the conversion equipment of speed and moment of torsion.
The lubricating system of
existing speed reducer output shaft assembly structure is to adopt centralized lubrication; Inject oil level to input shaft gear; Oil level is high, and just there is gravity pressure in lubricant oil itself, brings difficulty to box sealing; The leakage of lubricant oil, thus have influence on working life of output shaft assembly structure.
Summary of the invention
the invention provides a kind of straightening machine speed reducer output shaft assembly structure to the problems referred to above, when it can satisfy the performance requirement of high tenacity, big torque, guarantee the sealing of output shaft assembly structure.
It adopts following technical proposals:
It comprises
output shaft and is connected the gear on the output shaft neck through key, and the two ends of said output shaft are respectively installed with bearing, the bearing of an end; One end end face of the end face of one of which end and said gear contacts; The other end end face of said gear and the shaft shoulder of said output shaft contact, the bearing of the other end, and it contacts near the end face of a side of output shaft axle body and the shaft shoulder of said output shaft; The bearing at two ends; Its opposite side end face is pressed with lid respectively, and described lid is connected with casing respectively, it is characterized in that: the cooperation place of said lid and said output shaft is provided with the double density seal.
its further characteristic is: said bearing is a tapered roller bearing, is face-to-face layout; Said lid is fastened on the casing through hexagon socket head cap screw; Said bolt and pass through between the lid and be provided with compression spring.
The invention has the beneficial effects as follows:
In
said structure of the present invention, the setting of double density seal can be guaranteed the lid and the cooperation place sealing effect of said output shaft, the working life of guaranteeing total; And bearing to adopt the tapered roller bearing mounting type be to install face-to-face, rational in infrastructure, processing is easy, the proper functioning of assurance output shaft, impact resistance is big, stable and reliable operation has further guaranteed working life of total.
