Abstract
The utility model relates to a combined type bearing bush for a reciprocating pump, which takes two semicircular steel bushes as base bodies, tin bronze bush sheets are combined on the inner surface of two sides of each base body, a wear-resistant metal surface layer is respectively combined on the surface of the tin bronze bush sheet, corresponding to the inner surface of each base body, and oil storage holes which are distributed uniformly are arranged on the tin bronze bush sheet corresponding to the inner surface of each base body. In the combined type bearing bush structure for the reciprocating pump, the base bodies, the tin bronze bush sheets and the wear-resistant metal surface layer are combined in a way that the machining is convenient and the precision is ensured, a scraping adjusting matching process which has complex using process and needs long time is avoided, labor force and working time cost are greatly saved. The oil storage holes which are distributed uniformly on the tin bronze bush sheet can improve the lubricating effect, so as to reduce the fit clearance of the bearing bush and a crank shaft, and the vibration of the reciprocating pump is remarkably reduced and the operating noise is reduced. The combined type bearing bush for the reciprocating pump has the remarkable advantages of simplicity and simple processing technique.
Description
Technical field
The utility model belongs to reciprocating pump, particularly relates to a kind of reciprocating pump combined type bearing shell.
Background technique
In the prior art, the bearing shell of reciprocating pump supporting core transmission part bent axle is made of the two half rounds watt butt joint of symmetry, and two half rounds watt internal surface is coated mild alloy material composite bed respectively.
The above-mentioned bearing shell structure that mild alloy material composite bed is set exists in the reciprocating pump running with the bent axle matching gap makes reciprocating pump the defective that vibration is big, noise is high occur greatly; Simultaneously, the bearing shell structure that mild alloy material composite bed is set needs the practical problem that complicated, the consuming time long scraping adjustment of technology cooperates in reciprocating pump assembling and maintenance process.
Summary of the invention
The utility model be for solve above-mentioned by the bearing shell structure that mild alloy material composite bed is set in running and the described technical problem that exists respectively in the assembling, maintenance process, and a kind of reciprocating pump combined type bearing shell is proposed.
The utility model is taked following technological scheme for achieving the above object: this reciprocating pump comprises two half rounds watt of symmetry with the combined type bearing shell, feature is, with two half rounds watt is matrix, be compounded with the tin bronze tile at each matrix internal surface and dual-side, the tin bronze tiled surface of corresponding each matrix internal surface is compounded with the antifriction metal (AFM) top layer respectively, and the tin bronze tile of each matrix internal surface of described correspondence is provided with equally distributed oil storage hole.
The utility model can also be taked following technical measures:
The equally distributed oil storage hole area of described each tin bronze tile and account for respectively each tin bronze tiled surface long-pending 25%.
The beneficial effects of the utility model are with advantage: the structure that this reciprocating pump is adopted with the combined type bearing shell can make matrix, tin bronze tile and antifriction metal (AFM) top layer become for ease of processing and guarantee the mode that is assembled of precision, can avoid using complicated, the consuming time long scraping of technology to adjust engagement process, greatly save labour force and time cost.The tin bronze tile is provided with the flange that is compound in half rounds watt matrix both sides and helps ensureing the combination precision.The equally distributed oil storage hole of tin bronze tile setting can improve lubrication effect, thereby can reduce the matching gap of this combined type bearing shell and bent axle, has obviously reduced the vibration of reciprocating pump and has reduced the operation noise.The utlity model has the simply outstanding advantage of structure and processing technology.
Description of drawings
Accompanying drawing 1 is the example structure partial cutaway schematic.
Mark among the figure: 1 half rounds watt matrix, 2 tin bronze tiles, 2-1 oil storage hole, 3 antifriction metal (AFM) top layers.
Embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof.
This reciprocating pump constitutes with the combined type halfliner of combined type bearing shell by butt joint, and halfliner embodiment as shown in Figure 1, 2, 3.
Half rounds watt matrix 1 internal surface and dual-side are compounded with tin bronze tile 2 among the figure, and the tin bronze tiled surface of corresponding each matrix internal surface is compounded with antifriction metal (AFM) top layer 3 respectively, and the tin bronze tile of corresponding matrix internal surface is provided with equally distributed oil storage hole 2-1.
Shown in Fig. 2,3, the shape of oil storage hole 2-1 has circle and rectangular.
The equally distributed oil storage hole 2-1 of each tin bronze tile of the present utility model area and should account for respectively each tin bronze tiled surface long-pending 25%, the lubrication effect of this moment is best.
Claims (2)
1. reciprocating pump combined type bearing shell, two half rounds watt that comprise symmetry, it is characterized in that: with two half rounds watt is matrix, be compounded with the tin bronze tile at each matrix internal surface and dual-side, the tin bronze tile of corresponding each matrix internal surface is provided with equally distributed oil storage hole, and the tin bronze tiled surface of each matrix internal surface of described correspondence is compounded with the antifriction metal (AFM) top layer respectively.
2. reciprocating pump combined type bearing shell according to claim 1 is characterized in that: the equally distributed oil storage hole area of described each tin bronze tile and account for respectively each tin bronze tiled surface long-pending 25%.
