Abstract
The utility model relates to a weighing apparatus for a railway freight train rolling bearing oil feeder, which is composed of weighing machine mounting plates, weighing machine loading plates, round springs, a sensor, spring prepressing draw rods, etc., is arranged on a freight train rolling bearing oil feeder, provides metering foundation for a microcomputer to control the oil feeding amount of the rolling bearing, and is an indispensable weighing apparatus for automatically controlling the oil feeding amount of a bearing.
Description
The utility model relates to a kind of weighing bearing on the railway freight-car rolling bearing oiling machine and weighing device of oiling fat weight of being used for.
At present, railway freight-car rolling bearing oiling fat machine is 2 types (special use) oiling machines, its control of annotating oil quantity is the method that adopts oil pressure gauge and graduated cylinder metering, owing to reasons such as the loss of variation, grease viscosity change and the pipeline of blast and leakages, the oil quantity difficulty that enters bearing is controlled to making.
The purpose of this utility model provides a kind of weighing device, satisfies in the range of weighing that claims the bearing deadweight bearing notes oil quantity is carried out high-precision weighing requirement, for control bearing oiling fat amount provides measurement basis, is convenient to control annotating oil quantity with microcomputer.
The scheme that realizes above-mentioned purpose is: title bridge loading plate is set under the guide rail of former 2 types (special use) oiling fat machine and claims the bridge installing plate, middle position between two plates and four jiaos of symmetric positions are provided with sensor and four coil springs of the little range of high sensitivity respectively, form voltage divider principle in parallel, connect by spring precompressed pull bar between two plates, bear by spring deformation in spring range inner bearing deadweight 90%, the grease weight of deadweight remaining part and injection bearing is then born by sensor, thereby the heavy signal of oil is separated substantially with bearing deadweight signal, make the heavily useful range expansion of the sensor signal of generation of oil, be implemented in the purpose of in the big range of weighing bearing oiling fat being carried out the high precision weighing.
Now illustrate in conjunction with the accompanying drawings with concrete structure of the present utility model:
Accompanying drawing has represented the concrete structure of weighing device, it is mainly by claiming bridge installing plate 1, claiming bridge loading plate 6, spring precompressed pull bar 5, coil spring 2, sensor 4 etc. to form, claim bridge installing plate 1 to be fixed on the oiling machine, sensor 4 and coil spring 2 are arranged in the central authorities that claim bridge installing plate 1 and four jiaos, claim bridge loading plate 6 to place on the coil spring 2 and oiling machine guide rail 3 times, be pressed on the coil spring 2 by four jiaos spring precompressed pull bars 5.
The utlity model has and adopt voltage divider principle in parallel, characteristics simple in structure satisfy wide range on the railway freight-car rolling bearing oiling machine, the high-precision requirement of weighing, and simultaneously, it also can be used for other wide range, the high-precision place of weighing.
Claims (1)
1, a kind of weighing device that is used on the railway freight-car rolling bearing oiling machine, the formation that it is characterized in that this device is by the middle position that is fixed in the title bridge installing plate 1 on the oiling machine and four jiaos of symmetric positions sensor 4 and coil spring 2 to be housed respectively, claims bridge loading plate 6 to be pressed on the coil spring 2 by spring precompressed pull bar 5.
