Abstract
The utility model discloses a synchronous toothed belt driven velocity measuring device and belongs to the technical field of velocity measuring. The problem to be solved is to provide a low-cost, installation-convenient and maintenance-free device which uses the driving motion of the synchronous toothed belt to measure the velocity. In order to solve the problem, the utility model adopts the technical proposal as follows: the outer periphery of a roller is fixed with a synchronous toothed belt reversely arranged, and the outer end of the synchronous toothed belt is meshed with the synchronous toothed belt together; the middle of a shaft is fixed in the inner cavity of the synchronous toothed belt; both the left and the right sides of the shaft are respectively sleeved outwards with bearings and bearing seats, and the right end of the shaft is coaxially connected with an encoder through a flexible shaft device. The utility model can be widely applied to various linear and non-linear velocity measuring technical fields.
Description
Technical field
The utility model Synchronous Belt Drives speed measuring device belongs to the measuring speed technical field.
Background technology
Accurate inspected object relative shift, and, now be widely used in the every field of industry with the measurement mechanism that this displacement shows with digital mode.Because its appearance has improved work efficiency greatly, has alleviated working strength of workers.But, as so common measurement mechanism,, can only in large and medium-sized enterprise, use at present owing to its price height, installation, maintenance, maintenance difficulty, greatly limit the range of application of enterprise, restricted the raising of medium-sized and small enterprises product qualities and the raising of production efficiency.Measurement mechanism is formed by scale, slide rule and table, scale is to be fixed on a measurement assembly on the relative fixed object, slide rule is the measurement assembly that is fixed on the detected displacement object, table then is connected with slide rule by stube cable, its measuring principle is: in the relative motion of slide rule to scale, by the detected displacement signal of slide rule, be transferred on the table, by table displacement signal is shown with numeral, reach the measurement purpose.Present scale as the measurement mechanism assembly, mainly contain following several: 1. synchronously induction ruler 2. the grating chi 3. ball bar ruler 4. magnetic railings ruler 5. hold grid chi etc., in measurement mechanism, installation requirement to scale is tight especially, adding upper fixed ruler and slide rule all is precision optics or other accurate device, these devices are strict especially to environmental requirement, will damage slightly because of carelessness in the use, cause making entire measuring device not use; Because the length of scale can not be made oversizely, length is had the place of requirement in addition, need many scales butt joints, produce measuring error therefrom, directly influence measuring accuracy, and measure for non-rectilinear, this traditional measurement mechanism then can't carry out; These problems all greatly influence and have limited the popularization and the usable range of traditional measurement device.
The utility model content
The utility model overcomes the above-mentioned shortcoming that present traditional measurement device exists, and the device that a kind of cost is low, easy for installation, avoid maintaining, adopt Synchronous Belt Drives to test the speed is provided.
In order to address the above problem, the scheme that the utility model adopts is: the Synchronous Belt Drives speed measuring device, mainly comprise: cylinder, synchronous cog belt, synchromesh gear, axle, flexible axle device and scrambler, its structure is: the synchronous cog belt that is fixed with reverse installation on the excircle of cylinder, the outer end and the synchromesh gear of synchronous cog belt mesh together, the center fixed of axle is in the inner chamber of synchromesh gear, the left and right sides of axle outwards is set with bearing and bearing seat respectively, and the low order end of axle is coaxially connected with scrambler by the flexible axle device.
The excircle of above-mentioned cylinder and the fixed form of the synchronous cog belt of oppositely installing are gluing or are connected for riveted joint or for screw.
The material of above-mentioned synchronous cog belt is to be matrix with polyurethane, is strength layer with synthon.
The utility model compared with prior art has following beneficial effect:
1, in the utility model, as the synchronous cog belt of scale, can make random length according to measuring needs, therefore measuring length is not subjected to any restriction.
2, the utility model synchronous cog belt is installed simply, and this device cost of manufacture is low, does not need synchronous cog belt is carried out maintaining.
3, the utility model Synchronous Belt Drives speed measuring device is applicable to the occasion of non-rectilinear displacement measurement, is particularly suitable for the occasion that tests the speed of circular motion.
4, the utility model Synchronous Belt Drives speed measuring device, the measuring accuracy height, the adjustment of precision does not need synchronous cog belt to be adjusted again, and only needs error is detected, and will get final product in the error amount input coding device again.
