The invention discloses an assembling device and method for a double half inner ring angular contact ball bearing. The assembling device for the double half inner ring angular contact ball bearing comprises a base fixedly connected to an assembling vehicle and supported between the assembling vehicle and a front casing of a particle separator to form structural supporting; the middle portion of the base is provided with an up-down through assembling hole; a cylinder part used for expanding a rolling ball on a bearing retainer in the radial direction from the bearing outer ring assembling position of an inner cavity of the front casing of the particle separator so as to make the rolling ball enter a bearing outer ring track, and arranged on a front journal of a first-stage blade disk in aninserted connection sleeving manner to be in butt joint with a bearing front inner half ring on the front journal of the first-stage blade disk so as to make the rolling ball on the bearing retainer fall into the bearing front inner half ring is assembled in the assembling hole of the base in an inserted connection manner; and the inner diameter of the front end of the cylinder part is matched with the outer diameter of the front journal of the first-stage blade disk, and the outer diameter of the front end of the cylinder part is matched with the outer diameter of the corresponding portion ofthe bearing front inner half ring. By means of the assembling device and method for the double half inner ring angular contact ball bearing, the engine assembling difficulty is lowered, and the bearing is protected in the assembling process.
Description
technical field [0001] The invention relates to the technical field of aero-engine structure assembly, in particular to an assembly device for double-half inner-ring angular contact ball bearings. In addition, the present invention also relates to a method for assembling a double-half inner-ring angular contact ball bearing comprising the above-mentioned assembling device for a double-half inner-ring angular contact ball bearing. Background technique [0002] The No. 3 bearing of a certain type of turboshaft engine is a double-half inner ring angular contact ball bearing, which consists of 4 parts: bearing outer ring, bearing cage, front inner half ring of bearing, and rear inner half ring of bearing. During the overall assembly process of the engine, the outer ring of the bearing and the No. 3 bullet are interference fit and are integrally installed in the inner cavity of the front casing of the particle separator assembly, and then the ball cage is installed into the inner...
