Abstract

The utility model relates to a shaft component force measuring device, which is applicable to the measurement of the radial force of the shaft component, and consists of a square force measuring bracket, pressure sensors which are arranged on four faces of the square force measuring bracket, a T-shaped bolt which symmetrically passes through four faces of the square force measuring bracket in a cross shape, a bearing press ring which is connected with the top part of the T-shaped bolt and a bearing which is sleeved on a shaft, wherein the bearing press ring is stuck to a bearing, and the tail part of the T-shaped bolt is connected with the thread of the pressure sensor. When in movement, the radial force which is applied on the shaft is transferred to the bearing, and the radial force which is applied to the bearing is transferred to the pressure sensor through the bearing press ring and the bolt, so as to obtain the data. The shaft component force measuring device has simple structure and convenient and economical application, and is more convenient to be used and maintained compared with a collecting ring for only a pressure sensor within the measurement range of the radial force of the shaft is required to be bought.

Description

A kind of shaft part force measuring device
Technical field
The utility model relates to a kind of shaft part force measuring device, is particularly useful for the test of axial workpiece radial force.
Background technology
In mechanical engineering, because the discontinuity equalization of axial workpiece can make axle produce crooked, fatigue break, influence the normal operation of equipment, therefore need test, to guarantee safe in utilization in the engineering to this type of.But because the force transducer of Parts Measurement need be contained on the axle, the problem of the suffered power of measurement axis to solve foil gauge that rotates with the axis and the foil gauge of fixing.At present the mode of measurement axis is to adopt collector ring to measure, but higher, the complex structure of collector ring manufacturing cost safeguard, request for utilization is higher, and is uneconomical, unreasonable for the collection of some general data, and service time when longer thermal value higher.
Summary of the invention
The purpose of this utility model is to overcome the problem that exists in the prior art, and shaft part force measuring device a kind of simple in structure, easy to use, cheap, effective is provided
Shaft part force measuring device of the present utility model, it is by square frame shape dynamometry support, be located at the pressure transducer on four faces of square frame shape dynamometry support, be cross-shaped symmetrical and pass the interior tommyhead bolt of four faces of shaped as frame dynamometry support, bearing pressure ring that is connected with the tommyhead bolt top and the bearing that is enclosed within on the axle are formed, bearing pressure ring is fitted on the bearing, and the afterbody of tommyhead bolt is threaded with pressure transducer.
The bottom of described bearing pressure ring is provided with the arc groove that matches with bearing outside diameter; Bearing pressure ring top is provided with the dovetail groove that matches with tommyhead bolt.
Shaft part force measuring device of the present utility model is best suited for the test of axial workpiece radial force.It is made up of dynamometry support, pressure transducer, bolt, bearing pressure ring, bearing, axle and screw.Wherein arc groove is opened in the bearing pressure ring bottom, and the arc groove radius is identical with the outer ring radius of bearing.Arc groove contacts with bearing outer ring, has 4 bearing pressure rings and is distributed on the circumference of bearing, is connected with pressure transducer by bolt, and the pressure transducer periphery leans on screw retention on the dynamometry support.During operation, the axle force in radial passes to bearing, and the bearing force in radial passes to pressure transducer through bearing pressure ring, bolt, and then records data.It is simple in structure, and is easy to use, economical, and a pressure transducer that needs purchase to be fit to the axle radial force scope of surveying gets final product, than collector ring use, easy to maintenance.
