Abstract
The utility model discloses a bearing installation structure of an encoder. The bearing installation structure comprises a front end cover, a main shaft, bearings and clamp springs. The bearings and the main shaft are installed in the bearing chamber of the front end cover, a structure in which one or more bearings are serially installed together is adopted by the main shaft, and every two neighboring bearings are combined together or separated by a spacing ring. The technical scheme has the following advantages: the main shaft is formed by serially installing one or more bearings, the one or more bearings are serially installed together or every two neighboring bearings are separated by a workpiece, the main shaft and the bearings are positioned through a bearing retainer ring or the clamp springs, and the main shaft and the front end cover are positioned through workpieces, such as the clamp springs and the like. According to the utility model, two or more bearings are serially installed together, so the axial endplay and the radial run-out of the transmission shaft of the encoder can be effectively reduced, and advantages of stability and reliability can be realized on signals outputted by the encoder through the structure.
Description
Technical field
The utility model relates to the encoder techniques field, specifically the bearing mounting structure of scrambler.
Background technology
Scrambler is that signal (such as bit stream) or data are worked out, are converted to can be in order to the equipment of the signal form of communication, transmission and storage.Scrambler converts angular displacement or straight-line displacement to electric signal.Can be divided into contact and contactless two kinds according to the playback mode scrambler.Contact adopts brush output, and brush contact conduction region or insulation layer represent that the state of code is " 1 " or " 0 "; The contactless sensitive element of accepting is light activated element or magneto sensor, when adopting light activated element with photic zone and light tight district represent the state of code be " 1 " or " 0 ", the binary coding by " 1 " and " 0 " is converted to electric signal that machine code can read in order to communication, transmission and storage with the physical signalling that gathers.
Existing scrambler with the motor shaft junction because the architectural characteristic that is in transmission connection often can produce axial float and diameter run-out unavoidably, this situation has a strong impact on signal stabilization and the reliability of scrambler output.
The utility model content
For the problems referred to above, the utility model aims to provide a kind of axial float and diameter run-out that can effectively reduce the scrambler main shaft, so that the scrambler bearing mounting structure of signal stabilization.
For realizing this technical purpose, scheme of the present utility model is: a kind of bearing mounting structure of scrambler, comprise front end end cover, main shaft, bearing, jump ring, described bearing and main shaft are installed in the bearing chamber of front end end cover, and main shaft adopts one or more bearings structure that is installed in series; Also separate between the adjacent bearing together or with the interannular that spaces.
As preferably, main shaft and bearing are located with jump ring, locate with jump ring with front end end cover.
As preferably, the cavity between the bearing is full of grease.
As preferably, bearing chamber and bearing adopt clearance fit.
As preferably, bearing is fixed in the bearing chamber by glue.
As preferably, with jump ring bearing and transmission shaft are fixed in the front end end cover bearing chamber.
As preferably, bearing can be deep groove ball bearing, needle bearing or angular contact bearing etc., bearing band iron covering or Jiao Gai.
The beneficial effect of this programme is: the main shaft employing is one or more to be installed in series with head bearing, one or more bearings are installed in series together or are with workpiece that bearing and bearing is spaced apart, main shaft and bearing are located with workpiece such as jump rings with front end end cover with bearing ring washer or jump ring location.One or more bearings are installed in series and can effectively reduce axial float and the diameter run-out of scrambler transmission shaft, and this structure makes the signal stabilization of scrambler output reliable.
