Abstract
The invention discloses an improved structure of a front end cover of a motor, comprising the front end cover arranged at the front end of a motor casing, wherein an output shaft of the motor extends out of the front end cover; a cylindrical protruded part is arranged on an output shaft of a front end cover ring; and threads are arranged on the outer wall of the protruded wall. External threads are arranged on the cylindrical protrusion arranged on the output shaft of the front end cover ring of the motor; the cylindrical protrusion is in threaded connection with a transmission casing through the external threads in a sealing manner; and the improved structure is simple, convenient for installation and reliable in sealing and prevents oil stain in a transmission and other external sundries from entering the motor.
Description
Technical field
The present invention relates to a kind of motor front end housing structure-improved.
Background technology
Motor is connected with gearbox, and at present motor output shaft all adopts oil enveloping structure, to prevent that greasy dirt and other outside foreign material enter motor in the gearbox.A kind of low noise motor is just disclosed on October 4th, 2006 as Chinese utility model patent 200520015282.9, be provided with stator and rotor in the casing, rear end at rotor is provided with damping sheet, front end at casing is provided with front end housing, on front end housing, be provided with outside framework oil seal and rotor bearing, be provided with rotor bearing in the rearward end of casing.China's utility model patent 02220028.2 discloses a kind of slowspeed machine on February 5th, 2003, it includes self-lubricating plain bearing, front end housing, back-up ring, oil sealing, output shaft, low-speed gear, aluminum casing, self-lubricating plain bearing is loaded in the front end housing, back-up ring is loaded on and plays the axial location effect on the output shaft, and oil sealing is loaded in the front end housing.But the employing oil enveloping structure makes structure seem complicated, and installs inconvenient.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of simple in structure, easy for installation, reliable sealing motor front end housing structure-improved.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of motor front end housing structure-improved, comprise the front end housing of being located at the electric machine casing front end, motor output shaft stretches out front end housing, it is characterized in that: described front end bezel ring, output shaft is provided with the tubular protuberance, and described protuberance outer wall is provided with screw thread.
As preferably, described screw thread is a taper pipe thread.Connect by taper pipe thread, seal more reliably, the interior greasy dirt of gearbox can't enter in the motor.
The tubular that motor front end bezel ring, output shaft of the present invention is established is outstanding to be provided with external screw thread, is connected with the gear box casing thread seal by this external screw thread, and simple in structure, easy for installation, sealing is reliable, prevents that the interior greasy dirt of gearbox and other outside foreign material from entering motor.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is further described:
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, be the structure improved embodiment of a kind of motor front end housing of the present invention, comprise electric machine casing 1, be provided with front end housing 2 at the electric machine casing front end, motor output shaft 4 stretches out front end housing and stretches in the gear box casing 3, described front end bezel ring, output shaft is provided with tubular protuberance 5, and described protuberance 5 is provided with screw thread 6 and is connected with the gear box casing thread seal.Described screw thread 6 is a taper pipe thread.
Claims (2)
1. motor front end housing structure-improved, comprise the front end housing (2) of being located at electric machine casing (1) front end, motor output shaft (4) stretches out front end housing, it is characterized in that: described front end housing (2) ring output shaft (4) is provided with tubular protuberance (5), and described protuberance outer wall is provided with screw thread (6).
