Problems solved by technology

[0006] The purpose of the present invention is to provide an improved nail plate type metal plastic bearing (bearing), processing method and rolling mill. The structure of the product can simultaneously solve the problems existing in the high speed and low speed of the existing oil film bearing, and has the function of solid self-lubrication , in the environment of high-speed hydrodynamic lubrication, the lubrication is good at high speed, no tiles are burned when starting up and shutting down at slow speeds, no need to scrape tiles for maintenance, high reliability, less accident rate, long life, and can save a lot of manpower, material resources, Reduce energy loss

Embodiment 1

[0031] Example 1 is suitable for heavy loads. Thin layer 6 is arranged among the embodiment 2, and it is suitable for light load, and its lubricating effect is better than embodiment 1 when light load. Thin layer 6 has a thickness of 1-1.5 mm.

[0032] Manufacturing Technology

[0033] (1) Process flow: see Figure 4 .

[0034] (2) Process points

[0035] 1) Nail plate mill with single-roller drive: ① In the past, two rolls with the same diameter were driven by both rolls. Now it is necessary to change the single-roller drive, and the upper roll is changed to a hemp roll with nail holes. The radius of the hemp roller with nail holes > the radius of the smooth roller. Use it to generate different compression areas and generate demoulding torque, so that the nail plate can be automatically demoulded, otherwise manual demoulding is required. ②Nail hole depth h>2.7mm, in order to meet the requirements of rolled nail plate with nail height of 0.5-2.5mm. ③Arrangement of nail ...

Abstract

The invention discloses a nail board type metalplastic bearing shell, its producing technique and rolling machine. The plastic is filled in the empty holes beside the nail on the board. It features that the nails on the plate is arranged to arrays with empty holes filled among arrays. When lubricated with high speed liquor, the high speed lubricating is good. When Starting and shutting in a low speed, the shell will not be burned. No need to scrapping the shell while amendment. It is of high reliability, low accident rate, long service life and saves great man power, material and energy resources.

Description

technical field [0001] The invention relates to a nail plate type metal plastic bearing bush (or bearing) and its processing technology. Background technique [0002] I have previously patented ZL9538283.0 nail plate plastic self-lubricating composite plate and ZL99237906.7 nail plate type composite material bearing, and proposed a composite structure of metal nail plate and plastic, and proposed in ZL99237906.7 nail plate type composite material bearing The production and processing method of roll rolling is introduced. [0003] The current oil film bearings used in various machines with relatively fast operating speeds (up to the speed that can form oil film lubrication)-Babbitt alloy, aluminum, copper alloy and other bearings, have many shortcomings, such as easy to turn on and off under slow speed conditions. Burning tiles has a high accident rate, and tiles need to be scraped during maintenance. For some heavy-duty bearing tiles, a static pressure...
