Description

Изобретение относитс к рудничному транспорту и касаетс конструкции колесной пары рельсового транспортдогр средства, преимущественно шахтной вагонетки.The invention relates to mine transport and relates to the construction of a wheel pair of a rail vehicle, mainly a mine trolley.

Известна колесна пара транспортного средства, содержаща ось и два гкопеса, каждое из которых своей стушщей смонтировано на конце оси посредством двух конических подшипников , зафиксированных на оси торцовой гайкой р J.The known wheelset of the vehicle, containing an axis and two gopesa, each of which is mounted on the end of the axis by means of two tapered bearings fixed on the axis by an end nut p J.

эта колесна пара характеризуетс сложностью монтажа и регулировки осевого зазора подшипников, что снижает их надежность и долговечность . This wheelset is characterized by the difficulty of mounting and adjusting the axial clearance of bearings, which reduces their reliability and durability.

Цель изобретени - повьппение долговечности и облегчение регулировки осевого зазора подшипников.The purpose of the invention is to increase durability and facilitate adjustment of the axial clearance of bearings.

Указанна цель достигаетс тем, что между наружными кольцами каждой пары подшипников установлены параллельно два кольца, смежные поверхности которых выполнены конусообразны- ми, и между ними размещены тела качени , каждое из которых поджато регулировочным винтом, установленным в ступице колеса.This goal is achieved by the fact that between the outer rings of each pair of bearings two rings are installed parallel, the adjacent surfaces are tapered, and rolling bodies are placed between them, each of which is pressed by an adjusting screw installed in the wheel hub.

Кроме того, тела качени могут быть выполнены в виде шариков.In addition, the rolling bodies can be made in the form of balls.

На чертеже изображена часть колесной пары рельсового транспортного средства, частичный разрез.The drawing shows part of the wheelset of a rail vehicle, a partial section.

10ten

Колесна пара содержит колесо 1 ось 2, подшипники 3 и 4, упорное кольцо 5, крышку 6, пружину 7, гайку 8 , детали 9 и 10 лабиринтного The wheel pair contains the wheel 1 axle 2, bearings 3 and 4, the stop ring 5, the cover 6, the spring 7, the nut 8, the details 9 and 10 of the labyrinth

IS уплотнени , кольца 11 и 12с конусообразными поверхност ми и тела 13 качени между ними, которые упираютс в регулировочный винт 14 с гайкой 15 и стопорной шайбой 16. Внутренние IS seals, rings 11 and 12 with tapered surfaces and rolling bodies 13 between them, which abut against the adjusting screw 14 with nut 15 and lock washer 16. Internal

Claims

20 bearing rings are uncovered with a sleeve 17. Rings 11 and 12 with tapered surfaces abut against outer rings of bearings 3 and 4. As the rings and bodies 13 wear out of bearing bearing 3 and 4, axial gaps appear that eliminate the movement of bodies 13 rolling with adjusting screws 14 inside the cavity between the rings 11 and 12, the axial movement of these rings and the outer rings of the subgap pads 3 and 4 is achieved. cone shaped surfaces of rings 11 and 12 are selected from the conditions of self-braking body 13 rolling between the surfaces. Such a pair of wheels is characterized by a greater durability of the bearing assembly due to the regulation of the axial clearance of the bearings, while the adjustment is made available without opening the bearings. Due to the adjusted axial clearance of the bearings, the dynamic loads on the flange of the wheels are reduced and, consequently, the average service life of the wheelset increases. Invention Formula}. A wheel pair of a rail vehicle, predominantly a shaft trolley 04, containing an axle and two wheels, each with its hub mounted at the end of the axle by means of two conical bearings fixed to the axle with a face nut, so that and to facilitate the adjustment of the axial clearance of bearings, between the outer rings of each pair of bearings, two rings are installed parallel, the adjacent surfaces of which are tapered and filled with bodies to laziness, each of which is pressed against the adjusting screw mounted in the wheel hub.

2. A pair of wheel wheels according to claim 1, about which the rolling bodies performed as balls. Sources of information taken into account during the examination 1.
