The invention relates to bearings.

Closest to the invention is a bearing containing a liner mounted on the shaft and embracing, a sleeve mounted on the shaft, and the mounting sleeve, and the method of Assembly of the bearing, which consists in the installation of the liner and sleeve in the seat and the securing fasteners assembled bearing the repair technology.

The technical result of the invention is to simplify the construction and repair technology.

This is due to the fact that the bearing containing the liner, mounted on the shaft and embracing, a sleeve mounted on the shaft, and the mounting sleeve, the sleeve is made springy and split, as well as due to the fact that when performing a method of assembling a sliding bearing consisting in the installation of the liner and sleeve in the seat and fastening them by fastening elements with the subsequent Assembly of the bearing unit, the installation sleeve is produced in your seats after its extension.

The sleeve is made of the bent shape of seat. Cut the sleeves are made at an acute angle to the axis of the shaft or in the dovetail. The fastening elements made in the form of antennae, which is made on the sleeve and shaft are made relevant unicam grooves. The mounting sleeve is made in the form of screws, the holes of the sleeve and threaded holes formed on the shaft. The screws are designed with a Central hole corresponding to the hole for supplying oil to the bearings. After the extension sleeve antennae sleeve are aligned with the grooves on the shaft. After the extension sleeve combine ELA.

In Fig. 1 shows a bearing unit of Fig. 2 one alternative mounting sleeve of Fig. 3 the element mounting sleeve of Fig. 4 is another variant of the fastening sleeve.

The sliding bearing includes a sleeve 1, in one embodiment, performed slotted and grooved slit 2 in the form of a dovetail, or sleeve 3, in another embodiment, made split and springy with a slit 4 at an acute angle to the axis. The bearing contains an insert of two halves 5. The sleeve 1 (or 3) is mounted on the shaft 6 and the half 5 of the liner in the cylinder 7 and the cover 8 of the connecting rod.

When carrying sleeve 3 angle cut 4 it is secured by screws 9 having a Central opening 10 and installed in the holes 11 for the oil supply shaft 6. When running sleeve 1 with a slit in the dovetail it is fastened by means of antennae 12 therein and grooves (not shown) on the shaft 6.

The bearing is collected.

First shaft install the sleeve 1 (or 3) and attach the appropriate fastening elements, then in the head 7 and the cover 8 of the rod set half 5 of the liner. Then install the head and the cap on the sleeve and fastened to each other.

Bearing crankshaft and connecting rod operates as education liner 5, mounted rigidly in the cover 8 and the head 7 of the connecting rod. When worn bushings or liners replaced by a new set. The shaft 6 there is no need to handle. In the manufacture of the crankshaft 6 is no need for indigenous and crankpin be hardened by high frequency currents, as they do not wear out.

The implementation of bearings in the form of a sleeve and liner simplifies the design of the bearing unit, simplify their technology implementation, installation and dismantling. The implementation of the sliding bearing of the two rubbing together of parts allows you to choose the best pair of friction in order to achieve the lowest wear and simplification of the device. Performing oblique junction reduces knock on the bearing and reduces its wear, the execution of the sleeve over the cut in the dovetail simplifies the design and execution of antennae and grooves on the neck of the shaft simplifies mounting.

Sliding bearing // 2398141

FIELD: machine building.

SUBSTANCE: sliding bearing consists of half-round upper insertion and half-round lower insertion separated one from another. The upper insertion consists of the first oil-conducting channel for supply of lubricating material (motor oil) from outside into a gap between the bearing and a shaft and the second oil-conducting channel facilitating flow of oil in a circular direction of the bearing. The first channel includes an opening in internal circumference opened into internal circumference of the upper insertion. The upper insertion includes a part without an internal recess without a channel on a back side relative to the opening in internal circumference in the direction of shaft rotation. An auxiliary oil-conducting channel for oil release from the second channel is made in at least one of lower insertions and in a zone on the next side of the opening in circumference in the direction of rotation. The second channel runs to a front side in the direction of shaft rotation from the opening in internal circumference to the auxiliary channel. In the second version the upper insertion of the bearing included a front end part on the front side relative to the opening, while the lower insertion includes the back end part corresponding to the front part. The auxiliary channel is formed with channels of an unloading recess and a face made on the internal circular side of at least one of the front parts of the upper insertions and the back part of the lower insertion. Oil consumption of the face channel is bigger, than oil consumption of material in the channel of the unloading recess. Also there is claimed the facility of torque transfer and the engine containing the sliding bearing.

EFFECT: sliding bearing with decreased amount of lubricating material coming out of oil gap preventing damages caused with foreign impurities.

SUBSTANCE: method involves measurement of diameters of primary supports of case, main journals of crankshaft, their misalignment values, thickness of upper and lower inserts, sorting of parts as per dimensional groups, selection of sets of parts in a batch by simulating the assembly considering all the measurement parameters and calculation of total completing error. At that, inserts are chosen as to their thickness by calculating "working" gaps in the zone of their maximum approximation under load, considering the measurement parameters of each primary support and similar main journal. Parts are sorted, and at the same time, accuracy of radial gap is calculated by comparing it to allowable limit values of radial gaps and by choosing the measured dimensions of contact surface of completing parts, which are the closest as to the value. Simulation is performed by using geometrical plane model of mounting assembly and performing mathematical simulation and computer-aided selection of the required combination of sizes of thicknesses of upper and lower inserts of secondary journals. Then, the required thicknesses of inserts are chosen by deducting from "working gap" value the corresponding values of limit values of radial gaps in each similar pair of main bearing-main journal of crankshaft, by using the data of actual measured sizes of diameters of holes of primary support of diesel engine casing, main journals of crankshaft, thicknesses of upper and lower inserts of main sliding bearings using combinatory relationship of design radial gap.

EFFECT: improving the accuracy of radial gaps and efficiency of assembly process due to automation of completing process of multi-support bearing assembly.
