Description

Technical Field

[0001] The utility model belongs to the field of bearings, and in particular relates to a single-groove blind hole rocker bearing. Background Art

[0002] The primary function of a bearing is to support a rotating mechanical object, reduce friction during its motion, and ensure rotational accuracy. A rocker bearing is a type of bearing used to support a rotating mechanical object and reduce friction during its motion. Its key features include low friction, low power consumption, high mechanical efficiency, and easy starting. It supports the rotating shaft and its components, maintaining the shaft's normal operating position and rotational accuracy.

[0003] Since the bearing shell of the existing rocker arm bearing is tilted, dust easily enters between the upwardly tilted portion of the bearing shell and the ball, and the dust easily causes serious wear of the rocker arm bearing. Utility Model Content

[0004] The purpose of the utility model is to provide a single-groove blind hole rocker bearing, in which a limiting plate is arranged on the upward side of the bearing shell, which can not only block part of the dust but also play a role in limiting the ball.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A single-groove blind hole rocker bearing includes a bearing core, an inclined bearing shell and a ball. The bearing core is provided with a bearing core groove, the bearing shell is provided with a bearing shell groove, the ball is located between the bearing core groove and the bearing shell groove, and a limit plate is provided on the upwardly inclined side of the bearing shell, which presses against the ball.

[0007] The balls roll between the grooves of the bearing core and the bearing shell. The limit plate is located on the upward inclined side of the bearing shell, which can block most of the dust.

[0008] Furthermore, the limiting plate is provided with a limiting groove, the limiting groove matches the ball, and the ball is located in the limiting groove.

[0009] The balls roll in the limiting grooves on the limiting plates, playing the same role as the retainers in common bearing structures.

[0010] Furthermore, the bearing shell is provided with a fixing structure, one end of which presses the outer side of the limiting plate.

[0011] The fixing structure fixes the position of the limit plate in the bearing housing by pressing one side of the limit plate.

[0012] Furthermore, the fixing structure includes a connecting ring, an extension rod and an elastic pressure plate. The connecting ring is evenly distributed with extension rods, and an elastic pressure plate is provided at the end of the extension rod. The connecting ring is installed at the end of the bearing shell where the limit plate is not provided. The extension rod surrounds the outer wall of the bearing shell, and the elastic pressure plate is against the outer side of the limit plate.

[0013] The fixing structure uses an elastic pressure plate to press the limit plate against the ball, and the connecting ring and the extension rod surround the outer wall of the bearing shell, which facilitates the installation and disassembly of the fixing structure.

[0014] Furthermore, the elastic pressure plate includes a horizontal portion, a raised portion and an extrusion portion. The horizontal portion is installed at one end of the bearing shell provided with a limit plate. The horizontal portion is fixed to the bearing shell by screws. The raised portion protrudes outward and the extrusion portion presses against the limit plate.

[0015] The horizontal portion is used to be fixed on one side of the bearing housing. The raised portion and the extrusion portion provide elastic force for the limit plate, which can prevent the limit plate from excessively squeezing the ball and causing excessive friction between the limit groove and the ball.

[0016] Furthermore, the raised portion is trapezoidal.

[0017] Furthermore, the bearing shell is tilted in the vertical direction, and the tilt angles of the bearing core groove and the bearing shell groove are the same as the tilt angle of the bearing shell.

[0018] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0019] The balls roll between the grooves in the bearing core and the bearing housing. A retaining plate, located on the upwardly tilted side of the bearing housing, blocks most dust. The retaining plate has a retaining groove within which the balls roll, acting like a retainer in a common bearing structure.

[0020] The fixing structure uses an elastic pressure plate to hold the limit plate against the ball bearing. A connecting ring and extension rod surround the outer wall of the bearing housing, facilitating installation and removal of the fixing structure. The horizontal portion is fixed to one side of the bearing housing, while the raised portion and extrusion portion provide elastic force for the limit plate, preventing the limit plate from excessively squeezing the ball bearing and causing excessive friction between the limit groove and the ball bearing.

[0025] like Figs. 1-3 The single-groove blind hole rocker bearing shown in the figure comprises a bearing core 1, an inclined bearing shell 2, and a ball 3. A rocker 12 is provided on the top of the bearing shell 2. The bearing core 1 has a bearing core groove 4, and the bearing shell 2 has a bearing shell groove 5. The ball 3 is positioned between the bearing core groove 4 and the bearing shell groove 5. A stop plate 6 is provided on the upwardly inclined side of the bearing shell 2, which abuts against the ball 3. The bearing shell 2 is tilted vertically, with the inclination angles of the bearing core groove 4 and the bearing shell groove 5 being the same as that of the bearing shell 2. The stop plate 6 has a stop groove 7 that matches the ball 3, and the ball 3 is positioned in the stop groove 7.

[0026] Balls 3 roll between bearing core grooves 4 and bearing housing grooves 5. A retaining plate 6, located on the upwardly tilted side of bearing housing 2, blocks most dust. Balls 3 roll within retaining grooves 7 on retaining plate 6, functioning like a retainer in a conventional bearing structure.

[0027] The bearing housing 2 is fitted with a fixing structure 8, one end of which presses against the outside of the limit plate 6. The fixing structure 8 includes a connecting ring 9, extension rods 10, and an elastic pressure plate 11. The connecting ring 9 is evenly distributed with the extension rods 10, and the ends of the extension rods 10 are provided with elastic pressure plates 11. The connecting ring 9 is mounted on the end of the bearing housing 2 where the limit plate 6 is not provided. The extension rods 10 surround the outer wall of the bearing housing 2, and the elastic pressure plate 11 abuts against the outside of the limit plate 6.

[0028] The fixing structure 8 fixes the position of the limiting plate 6 in the bearing housing 2 by pressing one side of the limiting plate 6. Fig. 2 As shown, the elastic pressure plate 11 includes a horizontal portion 1101, a raised portion 1102 and an extrusion portion. The horizontal portion 1101 is installed at one end of the bearing shell 2 where a limit plate 6 is provided. The horizontal portion 1101 is fixed to the bearing shell 2 by a screw 13. The raised portion 1102 protrudes outward, and the extrusion portion 1103 presses against the limit plate 6.
