Abstract
The utility model discloses a mounting structure of an input shaft in a large gear box. Both ends of the input shaft (5) are respectively arranged in a box body (1) through cylindrical roller bearings (6 and 13); the cylindrical roller bearing (6) at one end is provided with a regulating ring (2) and an end cover (3) in sequence from inside to outside; an oil slinger (4) is arranged in the end cover (3) and the regulating ring (2); an outer ring of the cylindrical roller bearing (13) at the other end is provided with a regulating ring (7), a bearing block (12) and a gland (11) in sequence from inside to outside; the bearing block (12) is arranged on the box body (1); and an inner ring of the cylindrical roller bearing (13) is provided with a distance ring (9), a bidirectional thrust angular contact ball bearing (8) and two round nuts (10) in sequence from inside to outside. Due to the fact that the required bearings are reasonably selected, the mounting structure has reliable performance and can bear higher load, and the limit speed can meet the operating requirement of 1200 revolutions per minute (rpm) or above.
Description
Technical field
The utility model relates to mechanical field, is specifically related to the mounting structure of input shaft in a kind of large gear case.
Background technique
High speed, heavy-load gear box are used widely both at home and abroad at present, and maximum speed can reach more than the 1200rpm, and the gearbox high-speed axle bearing selects whether rationally directly to influence the normal operation of gear-box.In use, if selected bearing limit speed and limit load do not reach requirement, will have a strong impact on bearing working life, the serious consequence that causes production line to stop production.
Summary of the invention
The purpose of this utility model is: the mounting structure of input shaft in a kind of large gear case is provided, and the required bearing of this mounting structure choose reasonable, reliable performance can be born bigger load, and limit speed can satisfy the above usage requirement of 1200rpm again.
Technical solution of the present utility model is: the two ends of input shaft are installed in the casing by roller bearing respectively, wherein install successively from inside to outside on the end roller bearing and adjust ring, end cap, and disc is installed in end cap and adjusts in the ring;
The other end roller bearing outer ring is installed successively from inside to outside and is adjusted ring, bearing support, gland, and bearing support is installed on the casing, and the roller bearing inner ring is installed distance ring, bidirectional angular contact thrust ball bearing and two round nuts from inside to outside successively.
Advantage of the present utility model is: 1, when the design gear case, take into full account the use rotating speed and the maximum speed of institute's gas-distributing motor, guarantee that when selecting bearing of input shaft for use its limit speed and rated load all can satisfy the usage requirement of gear-box, this gearbox input shaft bearing adopts an end that a roller bearing is installed, the other end is installed a roller bearing and a bidirectional angular contact thrust ball bearing, utilize roller bearing to bear radial load, utilize bidirectional angular contact thrust ball bearing to bear thrust load, guarantee bearing life and the usage requirement of gear-box when running up, guarantee that bearing can bear certain thrust load and radial load, the limit speed of bearing reaches more than the 1200rpm, avoids bearing to select for use improper and the damage bearing; 2, this structure adopts two kinds of bearing stack mountings, has both guaranteed the limit speed of bearing, guarantees the bearing capacity of bearing again, realizes reliable high speed operation, guarantees the normal operation of equipment, and installation, maintenance is convenient, and usability is good.
