Abstract
The invention discloses a kind of stirring shaft supported gear in taper ribbon, heating, vacuum dryer driving ribbon to stir that is applied to and stir speed reducer, under the prerequisite not changing original gear speed reducer box body structure, utilize the upper ball cover position of former speed reducer output shaft that the bearing support increased is installed and make the supporting spacing between speed reducer output shaft two bearings meet rotational stabilization and the bearing strength requirement of installation stirring shaft.And stirring shaft two the bearings points speed reducer output shaft axis hole two ends lengthened replaced as the strong point of stirring shaft in former deceleration frame, equipment complete machine height is significantly reduced, reduce the restriction of installation space, extend a kind of using scope as current most advanced efficient vacuum drier, convenient for maintaining maintains.
Description
Technical field
The present invention relates to a kind of speed reducer stirred, particularly relate to chemical industry, pharmaceutical industry be applied in taper ribbon heating, vacuum dryer is used for drive ribbon stir speed reducer.
Background technique
Speed reducer is stirred with the produced gear of modern industrial technology, there is transmission effect high, long service life, low noise advantages, former universal gear reduction unit to be applied in tapered ribbon on heating drier, drive as stirring, the block bearing of stirring shaft must independently in frame be installed, in frame, the independent stirring shaft installed makes complete machine height superelevation, use as equipment is arranged in limited spatial altitude, the extreme difficulties of its repair demolition will be caused, particularly in tapered ribbon, heating, vacuum dryer is arranged on the use of pharmacy (GMP) dust proof workshop, because workshop absolute altitude and device height do not match, significant wastage will be caused to space.
Summary of the invention
Stirring shaft bearing type gear reduction unit of the present invention is on the basis of original gear reduction unit, the distance lengthening output shaft and strengthen between two bearings, and using the block bearing of speed reducer output shaft bearings at both ends as supporting stirring shaft, replace stirring shaft two the supporting point bearings in former frame, heating, vacuum dryer complete machine height in tapered ribbon is significantly reduced, and select the satisfactory output shaft bearing of bearing capacity, bear the load that stirring shaft increases simultaneously.Because stirring shaft is arranged in speed reducer output shaft hole, and the center hole of stirring shaft need by heating heating agent, the change of output shaft thermal expansion generation length will inevitably be caused, so the design will select rational bearing structure and mounting type.
According to scheme provided by the invention: under the prerequisite not changing former speed reducer box body structure, utilize on bearing cap position, former output shaft upper end and the bearing support increased is installed, make the spacing between the speed reducer output shaft two bearings of lengthening meet the requirement of stirring shaft rotational stabilization and bearing strength.Consider that dryer ribbon stirs interior heating and makes speed reducer output shaft be subject to thermal stretching, the installation precision of output shaft bearing can be destroyed.This programme in speed reducer output shaft upper end, will adopt pairing single-row tapered roller bearing, can be speed reducer output shaft and provide accurate axially locating.In speed reducer output shaft lower end, adopt roller bearing (selecting model with load and installing space for foundation), as there is rib N-type roller bearing inner ring both sides, outer ring is without rib, therefore the relative bearing housing of output shaft is allowed to do bi-directional axial displacement within the specific limits, namely can bear the length change that output shaft is caused by thermal expansion, therefore make non-locating bearing.
The speed reducer output shaft upper end bearing grease lubrication increased, and oil sealing is installed additional between bearing support and output shaft.
In order to install stirring shaft and drive stirring shaft to rotate in speed reducer output shaft axis hole, in speed reducer output shaft axis hole upper end and stirring shaft cooperation place, transmission driving torque is connected with flat key, in speed reducer output shaft axis hole lower end, stirring shaft locked by adapter sleeve, when screwing down adapter sleeve, the axis hole tapering utilizing adapter sleeve cylindrical to coordinate with output shaft makes adapter sleeve lock stirring shaft, when exiting screw, unclamps stirring shaft and is convenient to repair demolition.
Advantage of the present invention is:
1, effectively reduce the complete machine height of heating, vacuum dryer in tapered ribbon, bring the convenience of maintenance.
2, the restriction of installation space height is reduced.Extend a kind of using scope as current most advanced efficient vacuum drier.
Accompanying drawing illustrates:
Fig. 1: the structural drawing being stirring shaft bearing type gear reduction unit of the present invention.
Fig. 2: the structural drawing being former universal gear reduction unit.
Fig. 3: be the structural drawing that stirring shaft bearing type gear reduction unit of the present invention is arranged on heating, vacuum dryer in tapered ribbon.
Fig. 4: be the structural drawing that universal gear speed reducer is arranged on heating, vacuum dryer in tapered ribbon.
Embodiment:
As shown in Figure 1: stirring shaft bearing type gear reduction unit adds upper bearing bracket 4 on the basis of former universal gear speed reducer box body structure, be fixed on box body of speed reducer with screw 13, the output shaft 3 lengthened adopts pairing single-row tapered roller bearing 1 as output shaft axially locating, by the inside and outside circle of bearing cap 12 with stripped nut 15 difference rigid bearing 1.Roller bearing 2, in certain scope, allow output shaft 3 to do biaxially displacement relative to bearing housing 4, namely can bear the length change that output shaft 3 is caused by thermal expansion.Speed reducer output shaft bearing 1 grease lubrication, and oil sealing 5 is installed additional between upper bearing bracket 4 and output shaft 3.Speed reducer support 14 can connection frame again as the effect of output shaft lower ball cover fixed cylinder roller bearing 2 outer ring maintenance.Be connected transfer of torque with flat key 6 with stirring shaft 16 in the hole that speed reducer output shaft 3 upper end and stirring shaft coordinate, and be locked on speed reducer output shaft 3 with round nut 11, speed reducer output shaft 3 lower end is installed adapter sleeve 9 screw 8 and is locked stirring shaft 16.
