Abstract
The utility model discloses a connecting structure for connecting a speed-measuring encoder and a roll shaft, comprising a speed-measuring encoder and a roll shaft. One end of the roll shaft is fixedly matched and sleeved with a section of shaft sleeve which is coaxial with the roll shaft; the inner side end of the shaft sleeve is sealed, and the outer side end thereof is opened and provided with a sealed blocking cover; two rolling bearings are sleeved in the shaft sleeve at intervals; a central hole of the rolling bearing is matched and sleeved with a hollow shaft; a connecting shaft of the speed-measuring encoder is matched with and sleeved in the hollow shaft; and the free end of the connecting shaft is fixedly connected with the inner side end of the shaft sleeve. The utility model has simple structure and the working stability of the encoder is high when the roll shaft rotates with high speed.
Description
Technical field
The utility model relates to the syndeton of a kind of speed measuring coder and roll shaft.
Background technology
Speed measuring coder is as the crucial checkout equipment of steel rolling unit measuring speed, its with measure between the roll shaft to be connected positioning accuracy all of crucial importance for certainty of measurement and service life.At present, for bulky encoder, connected mode between itself and the roll shaft adopts the fixed support levelling to install more, and, then adopting the mode of welding cantilever shalving on roll shaft end axis bearing to install for the little encoder of volume, these existing mounting means all need take than the large equipment space, require also higher to solder technology, and faults such as fracture also take place in speed measuring coder connecting axle easily because of coaxial accuracy is not enough, influence enterprise's ordinary production.
The utility model content
The purpose of this utility model is to provide the syndeton of a kind of speed measuring coder and roll shaft, and its syndeton is simple, and it is little to take the device space, is easy to certainty of measurement height, good operating stability are installed.
The purpose of this utility model is achieved in that the syndeton of a kind of speed measuring coder and roll shaft, comprise speed measuring coder and roll shaft, the secure fit suit a nodal axisn cover in an end of roll shaft, axle sleeve and roll shaft coaxial line, the medial extremity sealing of axle sleeve, the outboard end of axle sleeve opens wide and is equipped with the sealing door, suit two rolling bearings at interval in axle sleeve, cooperate suit a hollow shaft in the centre bore of rolling bearing, the connecting axle engage sleeves of speed measuring coder is contained in the hollow shaft, and said connecting axle free end and axle sleeve medial extremity are fixed together.
When the utility model uses, the roll shaft of high speed rotating drives the rotation of speed measuring coder connecting axle by the axle sleeve medial extremity, because the connecting axle of speed measuring coder stretches in the roll shaft, so not only simple in structure, and do not take up room, also make the axiality between speed measuring coder connecting axle and the roll shaft be improved, guarantee the job stability of encoder, help to improve certainty of measurement.The utility model compact conformation is durable, and carrying is big, and the encoder of various volumes does not all need to weld outside support, and the life-span is long, the coaxial accuracy height; Be suitable for the demanding measuring roller of certainty of measurement, have promotional value.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is that master of the present utility model looks cross-sectional view.
The specific embodiment
The syndeton of a kind of speed measuring coder and roll shaft as shown in drawings, comprises speed measuring coder 1 and roll shaft 5, and the secure fit suit nodal axisn cover 6, axle sleeve 6 and roll shaft 5 coaxial lines in an end of roll shaft 5.The medial extremity sealing of axle sleeve 6, the outboard end of axle sleeve 6 opens wide and is equipped with sealing door 4, suit two rolling bearings 8 at interval in axle sleeve 6, cooperate suit a hollow shaft 2 in the centre bore of rolling bearing 8, connecting axle 7 engage sleeves of speed measuring coder are contained in the hollow shaft 2, and said connecting axle 7 free ends are connected by key with axle sleeve 6 medial extremitys and are fixed together.
One lubrication delivery passage is being set in the axis body of hollow shaft 2, and the import of this passage is positioned on the outside end face of hollow shaft 2, and the outlet of passage is arranged on hollow shaft 2 periphery walls between two rolling bearings 8.Can be convenient in axle sleeve 6, carry lubricating oil like this, so that rolling bearing 8 is carried out lubricated fully.
Cooperate suit a joint nylon bush 3 in the outboard end of hollow shaft 2, said connecting axle 7 passes from this nylon bush 3.Nylon bush 3 is installed is prevented to produce excessive amount of deflection, prevent to influence certainty of measurement because of the cantilever of encoder connecting axle 7 is long.In addition, because nylon bush 3 has self-lubricating function, when helping so also to guarantee that roll shaft runs up, the job stability of encoder and coaxial accuracy.
Claims (3)
1, the syndeton of a kind of speed measuring coder and roll shaft, comprise speed measuring coder (1) and roll shaft (5), it is characterized in that: the secure fit suit a nodal axisn cover (6) in an end of roll shaft (5), axle sleeve (6) and roll shaft (5) coaxial line, the medial extremity sealing of axle sleeve (6), the outboard end of axle sleeve (6) opens wide and is equipped with sealing door (4), suit two rolling bearings (8) at interval in axle sleeve (6), cooperate suit a hollow shaft (2) in the centre bore of rolling bearing (8), the connecting axle of speed measuring coder (7) engage sleeves is contained in the hollow shaft (2), and said connecting axle (7) free end and axle sleeve (6) medial extremity are fixed together.
2, the syndeton of speed measuring coder according to claim 1 and roll shaft, it is characterized in that: a lubrication delivery passage is being set in the axis body of hollow shaft (2), the import of this passage is positioned on the outside end face of hollow shaft (2), and the outlet of passage is arranged on hollow shaft (2) periphery wall between two rolling bearings (8).
3, the syndeton of speed measuring coder according to claim 1 and roll shaft is characterized in that: cooperate suit a joint nylon bush (3) in the outboard end of hollow shaft (2), said connecting axle (7) passes from this nylon bush (3).
