Description
Technical Field
The utility model relates to a stud installation device among wind generating set.
Background
At present, in a wind generating set, in order to ensure the pretightening force requirement of connection between components and improve the accuracy and reliability of the set, main bearing components such as a variable pitch bearing, a main bearing seat and the like are all installed in a way that a stud bolt is pretightened through a hydraulic stretcher. Because the hydraulic stretcher has corresponding requirements on the leakage size of the stud relative to the mounting surface and the number of the studs is large, the mounting efficiency of the whole machine is influenced by the mounting of the studs.
The traditional installation mode is as follows: a workshop assembly worker manually screws the stud into the threaded mounting hole, and the screwing depth of the stud is measured through the ruler, so that the working and using requirements of the hydraulic stretcher are met. In the wind power market, the number of studs required to be installed on a variable pitch bearing of a low-wind-speed large-impeller unit exceeds 300, the assembling efficiency of the whole machine is affected by the hand-screwing assembling process, the screwing size of the studs is difficult to control, and the assembling requirement of the existing wind power unit is difficult to meet.
Therefore, a new device is needed to improve the assembly efficiency of the stud bolt on the premise of ensuring the assembly safety.

Detailed Description
As shown in fig. 1-3, the utility model provides a quick installation device of stud among wind generating set, include:
a rotating shaft 3 having hexagonal socket holes at both ends thereof;
the main bearing 2 is sleeved outside the rotating shaft 3 and is axially positioned by a clamp spring 8;
the bearing end cover 1 is fixedly sleeved with an outer ring of the main bearing 2;
a positioning sleeve 4, one end of which is fixedly connected with the bearing end cover 1 by a fastener 7 (such as a bolt and a nut);
an adjusting sleeve 5 which is connected with the other end of the positioning sleeve 4 through a thread, and the length of the adjusting sleeve 5 extending out of the positioning sleeve 4 can be changed through the thread connection;
a hexagonal connection wrench 9, which passes through the positioning sleeve 4, and one end of which is in transmission connection with the inner hexagonal hole at one end of the rotating shaft 3;
the stud 6 (preferably adopting a GB901-1988 standard part) is provided with a hexagon socket (preferably adopting a hexagon socket of a national standard GB70.2-2008 and a specification M16) on the non-screwed surface, and the hexagon socket is in transmission connection with the other end of the hexagonal connection wrench 9.
The utility model discloses in the time of using, will stud 6's twist face is aimed at the screw on the installation face, then inserts with the allen key on electric spanner or the air wrench in the interior hexagonal hole on the 3 other ends of rotation axis starts electric spanner or air wrench make rotation axis 3 fast revolution to drive hexagon in proper order and connect spanner 9 and stud 6 fast synchronous revolution, can make during the screw on the installation face is twisted fast to stud 6's twist end, until the overhanging end of adjusting sleeve 5 takes place to interfere with the installation face.
