Abstract
The invention relates to an installation process of a large end gear. The installation process includes the following steps that equipment is vertically placed in an installation position through a crane, and the end face of a gear sleeve where the large gear needs to be installed is placed upwards; the large gear is heated at the temperature of 180 DEG C-200 DEG C; the heated large gear is installed on the gear sleeve, and attention is paid to avoiding of collision between the gear sleeve and the gear in the installation process; and after the gear is cooled to the room temperature, a pin hole is drilled in the joint of the gear and the gear sleeve, a threaded hole is drilled and bored on the basis of the pin hole, then a pin is arranged, a screw is screwed in, and the screw is made to abut on the pin in the pin hole. The pin is a cylindrical pin with an internal thread. The screw is a hexagon socket set screw with a flat point. The two end faces of the large gear are provided with auxiliary holes distributed evenly and annularly. The installation process has the advantages that the gear sleeve is used, the load intensity of whole equipment is greatly increased, and a crushing phenomenon is not liable to occur in a high-intensity working state; the gear sleeve is well matched with the gear and is not liable to fall off.
Description
Technical field
The present invention relates to a kind of gear mounting process, be specifically related to a kind of end gear wheel mounting process.
Background technology
A lot of machinery all will rely on driven by motor gear wheel to realize rotating, gear wheel plays very important effect in rotation, the installation of gear wheel is in the past all first on main shaft, install disk, being screwed by gear wheel is connected on disk again, although this method is simply conventional, but also there is a lot of defect, 1. the axial strength of disk is inadequate, easily causes bulk deformation; 2. the thickness low LCL of disk easily causes conquassation.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of intensity high, do not allow flimsy end gear wheel mounting process.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of end gear wheel mounting process, and its innovative point is: its step is as follows:
Step one: utilize crane to be vertically placed on installation site by equipment, the geared sleeve end face need installing gear wheel is upwards placed;
Step 2: the heating temperatures gear wheel adopting 180 DEG C-200 DEG C;
Step 3: be installed on geared sleeve by the gear wheel after heating, notices in installation process that avoiding geared sleeve and gear to produce collides;
Step 4: after gear cool to room temperature, bores boring screwed hole at gear and geared sleeve joint draw-bore, then loads pin, be screwed into screw on the basis of pin-and-hole, makes screw hold out against pin in hole.
Further, described pin is cylindrical pin with internal thread.
Further, described screw is interior hexagonal flush end holding screw.
Further, described gear wheel both ends of the surface have fabrication hole uniform in the form of a ring.
Further, described canine tooth wheel case and gear wheel mating surface have a protruding step, this step is identical with gear wheel width apart from the distance of canine tooth wheel case end face.
The invention has the advantages that:
(1) use geared sleeve instead, considerably increase the load intensity of machinery integral, under large duty work state, also not easily produce conquassation phenomenon; Geared sleeve and gear are worked good difficult drop-off;
(2) adopt cylindrical pin with internal thread, be convenient to dismounting;
(3) adopt interior hexagonal flush end holding screw, ensure axial location, ailhead does not expose end face, and tightening is respond well;
(4) because gear wheel volume is excessive, the fabrication hole on its end face well solves the lifting problem of gear wheel;
(5) gear wheel and canine tooth wheel case end face, not easily generation scraping elegant in appearance does not hinder installation and the operation of miscellaneous part.
