"Gazelle" Gas-2705>> Transmission>> The back bridge>> Survey and the control of a technical condition of details of the back bridge
Details of the disassembled back bridge (except for bearings) to take in a washing solution, and then to wash out and attentively to examine.
Details with cracks to replace. At presence on mechanically processed surfaces of details забоин, agnails and other roughnesses to smooth out them for maintenance good прилегания the interfaced details. Thus it is necessary to pay special attention on a condition of landing surfaces under bearings.
To check up, whether is not present on rings of bearings задиров or traces of non-uniform deterioration. To check up a condition of end faces of rollers. Step deterioration of end faces of rollers testifies to an insufficient preliminary inhaling of bearings or about a warp of rollers.
To examine teeths of leading and conducted gear wheels and to check up, whether is not present on them задиров or traces of excessive deterioration. The worn out gear wheels and gear wheels with teases for the further work are unsuitable.
Temporarily to establish covers of bearings of differential and to check up ввертывание nuts. Nuts should be turned freely. The end faces of nuts adjoining to bearings, should be perpendicular carving axes. Palpation of these end faces concerning a carving axis should be no more than 0,02 mm. The surface of end faces should be pure and smooth, should not have step deterioration.
It is necessary to be convinced that covers of bearings are established on that party on which they were processed.
The end face of a flange of the leading gear wheel, adjoining to the bearing, should be smooth, in need of it it is necessary to grind. The second end face of a flange adjoining to a washer, also should be smooth, roughnesses and забоины at flange end faces weaken an inhaling of bearings. The flange neck should not have забоин, scratches, the big deterioration in a zone of work of a cuff, on заходной to a facet should not be sharp edges.
Carter of the bridge should not have damages and residual deformation. Surfaces of nests under bearings should be smooth, the carving under nuts of bearings of differential should not have damages. It is necessary to remove all roughnesses and agnails from landing surfaces картера a reducer. To clean oil channels.
To examine teeths and basic surfaces of gear wheels of semiaxes and satellites, basic and landing surfaces of boxes of satellites. They should be smooth, without dents and задиров and not have non-uniform deterioration or наволакивания metal. Deterioration of a neck of a semiaxial gear wheel can cause the raised noise of the back bridge. Deterioration of basic surfaces or basic washers causes increase in a lateral backlash in gearing of gear wheels of differential and infringement of correct gearing of gear wheels.
To check up density прилегания internal rings of bearings of differential to basic surfaces of boxes of satellites of differential — щуп 0,03 mm should not pass between a ring and a box end face. Internal rings should not rotate freely on necks of boxes.
To pay special attention on that adjoining surfaces of both boxes of satellites of differential and a surface of a flange of fastening of a conducted gear wheel were smooth, without agnails.
It is necessary to check up palpation of "nape" of a conducted gear wheel, as is shown in fig. 5.39 — for the one-piece back bridge (for the back bridge with a type beam банджо — it is similar, at the removed reducer). Admissible palpation — 0,08 mm. If at check it will appear that palpation exceeds the specified size it is possible to assume that deformation of a conducted gear wheel, damage of boxes of differential or excessive deterioration of bearings takes place. Unsuitable details repair or replace.
Carter of the bridge should not have considerable deterioration in a zone of work of a cuff of a nave, the surface under a cuff should be smooth, without scratches and забоин.
