Abstract
The utility model belongs to the technical field of transporting equipment parts, in particular a non-contact unidirectional roller which solves the problem that the existing unidirectional roller is not suitable for being used in mal-conditions. The non-contact unidirectional roller comprises a roller sheet and a roller shaft, wherein the roller sheet is installed on the roller shaft through a bearing block and a bearing; the bearing arranged in the roller sheet comprises an inner ring and an outer ring which are arranged coaxially; a roller path is arranged between the inner ring and the outer ring and is internally and evenly distributed with a plurality of rotatable wedge-shaped blocks; the rotating shaft of the wedge-shaped block is provided with a spring; and a sealing component and a shaft elastic damping ring are arranged outside the bearing. The roller has the following benefits: 1. the roller can be used in the mal-conditions with any installation angle, dustiness, moist and high temperature; 2. when the roller operates in the forward direction, the wedge-shaped block is deflected under the action of the centrifugal force to be separated from the inner and outer ring roller paths of the bearing, thus leading to small rotation resistance; and 3. when the roller operates reversely, the wedge-shaped block is contacted with the inner and outer ring roller paths of the bearing under the action of the spring force to tightly wedge the paths together. The conveyer belt adopts sliding friction instead of the rolling friction, thus preventing the conveyer belt from gliding and being conductive to safe operation.
Description
Technical field
The utility model belongs to transportation device parts technical field, specifically is the contactless One-way cradle roll that a kind of large inclination belt conveyor uses under any setting angle, many dirt, humidity, hi-heat mal-condition.
Background technology
At present, One-way cradle roll has gravity type boat davit One-way cradle roll and two kinds of forms of ball-type One-way cradle roll, and high spud angle conveyer carrying roller group is generally used 25 ° of-45 ° of V-type deep trouth groups and 25 ° of-60 ° of V-type deep trouth groups.When the delivery conduit inclination angle surpassed 18 °, 25 °-60 ° V-type deep trouth group side carrying rollers lost action of gravity, and the side carrying roller can two-wayly rotate, and did not have the load-transfer device downslide effect that prevents when broken belt, reversing take place.The ball-type One-way cradle roll can get rusty at many dirt, the moist environment spring plank of being hit by a bullet, and stops ball to roll.Difficulty can appear being rotated in the forward in the ball-type One-way cradle roll, increases the conveyer running resistance.
Summary of the invention
The utility model provides a kind of large inclination belt conveyor to be used in any setting angle, many dirt, humidity, the hi-heat mal-condition contactless One-way cradle roll of use down in order to solve the problems referred to above that existing One-way cradle roll exists.
The utility model adopts following technical scheme to realize:
Contactless One-way cradle roll, comprise roller skin and roller carrier shaft, the roller skin by bearing seat and bearing installation on roller carrier shaft, it is characterized in that being located at inner ring and the outer ring that roller skin in-to-in bearing comprises coaxial setting, form raceway between the inside and outside circle, be laid with some rotating wedges in the raceway, on the turning cylinder of wedge spring be set, bearing is provided with poted assemblies and circlip for shaft outward.
Principle of the present utility model is to have a plurality of wedges to be distributed in the inside and outside circle of bearing to form in the raceway in carrying roller inside, when the outer ring forward turns round, the moving wedge of roller belt rotates together, when rotating speed within the specific limits the time, wedge deflects under centrifugal must acting on, disengage with bearing enclose, thereby realize not having the wearing and tearing running.When the antiport of outer ring, wedge contacts with bearing enclose under the effect of spring force, and its wedging is integral and can not rotates.
The utlity model has following beneficial effect:
1, can use under setting angle, many dirt, humidity, the hi-heat mal-condition arbitrarily.
When 2, the carrying roller forward turned round, wedge deflected under action of centrifugal force and the bearing enclose raceway disengages, and rotational resistance is little.
3, when the carrying roller antiport, wedge contacts with the bearing enclose raceway under the effect of spring force, and its wedging is integral.Load-transfer device becomes cliding friction by friction of rolling, stops load-transfer device to glide, and helps safety in production.

Fig. 4 is a wedge free rotation state cutaway view
Among the figure: 1-noncontact One-way cradle roll, 2-roller skin, 3-roller carrier shaft, 4-bearing seat, 5-bearing, 6-wedge, 7-spring, 8-poted assemblies, 9-circlip for shaft.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Contactless One-way cradle roll shown in Figure 1 installation site.
Integral structure shown in Figure 2 is built front view: the utility model keystone configuration is made up of roller skin 2, roller carrier shaft 3, bearing seat 4, bearing 5, wedge 6, spring 7, poted assemblies 8, circlip for shaft 9.Roller skin 2 is the carrying roller swivel.Circlip for shaft 9 is stuck on the roller carrier shaft 3.Roller skin 2 two ends are symmetrically welded bearing seat 4, and roller carrier shaft 3 passes from bearing seat 4.To be installed in the middle of the roller skin 2.Wedge 6, spring 7 are installed in the bearing 5.Bearing 5, poted assemblies 8 are installed on bearing seat 4.Circlip for shaft 9 fixes on roller carrier shaft 3.Fill 2/3 grease in bearing 5 bearing chambers, in poted assemblies 8 spaces, guarantee that rotation flexibly.
Fig. 3, wedge non-return state shown in Figure 4, free rotation state cutaway view: when the outer ring forward turns round, roller skin 2 drives bearing 5 outer rings, wedge 6 rotates together, when rotating speed within the specific limits the time, wedge 6 deflects under centrifugal must acting on, disengage with bearing enclose 5, thereby realize not having the wearing and tearing running.When the antiport of outer ring, wedge 6 contacts with bearing 5 Internal and external cycles under the effect of spring 7, and its wedging is integral and can not rotates.The even interference fit that adopts of bearing 5 inner rings and roller carrier shaft 3, bearing 5 outer rings and bearing seat 4 endoporus is to guarantee the transmission of torque.Wedge 6 materials adopt GCrl5 bearing steel Quenching Treatment, and are consistent with bearing 5 Internal and external cycle materials to guarantee wedge 6, are not worn during check dress attitude.Wedge 6 upper and lower surfaces and bearing 5 Internal and external cycle slideways are sphere, and wedge 6 is easy to break away from the rotation of realization no touch with bearing 5 Internal and external cycle slideways when being rotated in the forward.
