Console mounting axis

 

The invention relates to mechanical engineering and can be used in internal combustion engines. Console mounting axis of the thrust flange is made on the wall of the crankcase of the internal combustion engine, and the end of the axis closes the speed of the oil cavity made in the partition. The preload axle flange to the end face of the crankcase of the internal combustion engine supported by a Central bolt passing through the axis or bolts passing through the flange axis. Bolt passing through the axis, or bolts passing through holes in the flange, screwed into the cover cavity side opposite to the flange axis, the diameter of the cover is larger than the hole closed by the end of the axis. The technical result is increased reliability of the cantilever mounting of the axle to the end face of the crankcase. 2 Il.

The invention relates to mechanical engineering and can be used in internal combustion engines (ice).

Known cantilever mount axis [1] installed on her gear, which is made on the wall of the crankcase of the engine. Flange axis using concentric spaced bolts attached to the end walls. The Central bolt inside the axis, priimetsa oil bearing gear goes into the internal cavity axis, and then on the other axial drilling is supplied to the sliding bearing. Console mounting axis has structural complexity, because has a flange mount and the Central bolt. The oil in the gear cavity, under pressure tends to press the washer from the end of the axis, stretching the Central bolt. This reduces the reliability of the design, especially if the gear has helical teeth, occurs when the axial force from the transmission of torque directed in the direction of thrust washers. The Central bolt can be extended, and its tightening to weaken.

It is also known cantilever mount axis [2] is installed on the gear train, which is made on the wall of the crankcase of the engine. Axis has developed the flange. With the help of spaced apart by the diameter of the axle bolts fastened to the end walls of the crankcase. Thrust washer mounted on the opposite flange end of the axis by means of additional bolts, prevents axial movement of the gear train. For lubrication of the bearing oil drilling in the wall of the crankcase flows into the axial drilling axis and for lateral drilling to the sliding bearing of the gear train. Located in the inner cavity axis under the pressure of the oil tends to press the axle from the end of the plumage is of ergorace Carter.

The present invention is to improve the reliability of the cantilever mounting of the axle to the end face of the crankcase.

The solution of the problem is due to the fact that in a console mount axis thrust flange, which is made on the wall of the crankcase of the internal combustion engine, in which the end of the axis closes the speed of the oil cavity made in the partition, and the preload axle flange to the end face of the crankcase of the internal combustion engine supported by a Central bolt passing through the axis or bolts passing through the flange, the Central bolt passing through the axis, or bolts passing through holes in the flange screwed into the cover cavity side opposite to the flange axis, the diameter of the cover is larger than the hole, closed end of the axis.

New the essential features in the proposed design is that the bolt or bolts screwed into the cover located on the back relative to the axis of the end face of the partition. The oil cavity is closed by an end face axis and a lid made in such a way that its diameter adjacent to the cover, is made larger than the diameter close to the axis.

The proposed design can increase the reliability consuling replayability by the difference in diameters of the oil cavity, close the lid and the end of the axis.

New significant features of the proposed mount cantilever axis is not inherent in other known solutions.

The set of essential features of the claimed invention in sufficient and necessary to achieve provided by the invention technical result of the task.

The essence of the invention is illustrated by drawings, where: Fig.1 shows a console center bolt; Fig.2 - console mounting bolts for the axle flange.

Design cantilever mounting consists of axis 1, is installed on the end walls 2 of the crankcase of the engine. On axis 1 set gear 3. By the inverse of axis 1 on the end walls 2, cover 4 is installed. In the cover 4 is screwed into the Central bolt 5, which is placed in the inner cavity 6 axis 1. The bolt 5 through the thrust washer 7 are pressed for axis 1 to the end walls 2. In the partition 2 has a stepped cavity 8. The diameter D of the cavity 8, closed by a cover 4 made larger than the diameter d of the closed end of axis 1. In the chamber 8 under pressure channel 9 receives the oil from the oil line of the engine (not shown) for lubrication of the sliding bearing 10 gears 3. Oil from the cavity 8 is supplied to vnutrennykh from the ends of the septum end of axis 1 and the end cap 4. On the axis the force of oil pressurewhere p is the pressure oil in the cavity 8.

On the cover force oil pressureBecause the axis 1 and the cover 4 are connected by a Central bolt 5 and D>d, axis 1 will further tighten the end walls 2 with the power ofAdditional force preload axis 1 to the end walls 2 through the oil pressure increases the reliability of the console mounting axis.

In Fig.2 shows a cantilever mount axis using concentric spaced bolts 12 passing through holes in the flange of the axis 1, the wall of partition 2 and screwed into the cap 4. Thrust washer 7 is tightened to the end of axis 1 by bolts 13. Due to the fact that the diameter D is closed by a cover that is larger than the diameter d of the closed end face of the axle 1, axle bolts 12, in addition to the force from their tightened, tightened oil pressure cavity 8 to the end walls 2. This significantly increases the reliability of the console mounting, as by a slight decrease bolts (due to the collapse of the mountaineers, the collapse of the thread) is compensated by the preload axis due to oil pressure. From the cavity 8 to the oil cavity 6, and channel 9 is supplied to the population additionally, while maintaining simplicity of design is used to improve the reliability of the console mounting axis.
