Abstract
The utility model relates to a totally sealed plastic roller which comprises a roller cylinder body (5), a roller shaft (1), a bearing (4) and a bearing base (3). The totally sealed plastic roller is characterized in that the bearing base (3) is a cylinder which takes the roller shaft (1) as a central shaft. The external end surface of the cylinder is a round annular plane. The center of the external end surface is provided with a shaft sleeve (10) which extrudes outwards. A coaxial round cylindrical bearing fastening ring (8) is arranged in the round cylindrical outer wall (7) of the bearing base (3). The bearing (4) is embedded in the bearing fastening ring (8) which is closely matched with the bearing. The shaft sleeve (10) arranged on the outside of the bearing base (3) is sleeved with a rubber sealing ring (2) which is a round cylindrical body with an annular end surface. The inner cycle of the annular end surface is provided with a lip cycle (12) which extrudes outwards. The totally sealed plastic roller has the advantages of simple structure, maximally simplified parts, superior dustproof performance, good heat dissipating effect, long surface live, stable operation and long working time adaptation.
Description
Technical field
The utility model relates to gearing, is a kind of hermetically sealed plastic conveyer roller specifically.
Background technology
Carrying roller is to use gearing very widely, because the work-hours of idler pulley is long, intensity is big, thus to the continuous smoothness of operation of carrying roller, prevent dust, heat dispersion has relatively high expectations.Traditional carrying roller is because of bearing more or less has a. g. and airiness with the external world, makes to be subjected to sand, dust pollution to cause the bearing working mal in the carrying roller long-term work process, and the carrying roller bulk life time shortens.Patent No. ZL200630025479.0 " belt conveyor plastic seal carrying roller " discloses a kind of sealing idler roller structure, but its part is many, and the structure in the bearing seat outside still dislikes complicated, thereby anti-dust performance is affected.
Summary of the invention
The purpose of this utility model provides a kind of structure to be simplified more, and anti-dust performance is good, has the hermetically sealed plastic conveyer roller of long life of heat dispersion concurrently.
Described hermetically sealed plastic conveyer roller, comprise carrying roller cylinder 5, roller carrier shaft 1, bearing 4, bearing seat 3, the two ends of roller carrier shaft 1 are with a bearing 4 respectively, roller carrier shaft 1 and bearing 4 inner ring flush fits, bearing 4 outer rings and bearing seat 3 flush fits, bearing seat 3 is locked mutually by the barb in its outside and the groove in the carrying roller cylinder 5, it is characterized in that: described bearing seat 3 be a kind of be the cylindrical of center shaft with roller carrier shaft 1, its outer face is zero-lash annular arrangement plane, the center of outer face is provided with the axle sleeve 10 to outer lug, be provided with coaxial cylindrical bearing tight loop 8 in the cylindrical outer wall 7 of bearing seat 3, bearing 4 is embedded in the friction tight with it bearing tight loop 8.Be with rubber seal 2 outside the axle sleeve 10 in described bearing seat 3 outsides, rubber seal 2 is cylinders of an a kind of end band shape end face, and the interior astragal of annular end face is the lip circle 12 of projection laterally.Establish the bearing saddle 9 that sinks in the described bearing tight loop 8, perpendicular to axial directionly between bearing saddle 9 and the axle sleeve 10 be connected with many radial fan reinforced ribs 11, also be connected with many radial superpower reinforced ribs 6 between bearing tight loop 8 and the outer wall 7.
The utility model is simple in structure, and parts are farthest simplified, and anti-dust performance is superior simultaneously, and good heat dissipation effect, thereby long service life operate steadily, and can condition oneself to long hours of work.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the bearing block structure scheme drawing,
Fig. 3 is the upward view of Fig. 2,
Fig. 4 is the rubber seal structural representation.
Among the figure: 1-roller carrier shaft, 2-rubber seal, 3-bearing seat, 4-bearing, 5-carrying roller cylinder, the superpower reinforced rib of 6-, 7-outer wall, 8-bearing tight loop, 9-bearing saddle, 10-axle sleeve, 11-fan reinforced rib, 12-lip circle.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified: as Fig. 1,2,3, shown in 4, described hermetically sealed plastic conveyer roller, comprise carrying roller cylinder 5, roller carrier shaft 1, bearing 4, bearing seat 3, the two ends of roller carrier shaft 1 are with a bearing 4 respectively, roller carrier shaft 1 and bearing 4 inner ring flush fits, bearing 4 outer rings and bearing seat 3 flush fits, bearing seat 3 is locked mutually by the barb in its outside and the groove in the carrying roller cylinder 5, it is characterized in that: it is the cylindrical of center shaft that described bearing seat 3 is with roller carrier shaft 1, its outer face is zero-lash annular arrangement plane, the center of outer face is provided with the axle sleeve 10 to outer lug, be provided with coaxial cylindrical bearing tight loop 8 in the cylindrical outer wall 7 of bearing seat 3, bearing 4 is embedded in the friction tight with it bearing tight loop 8.Be with rubber seal 2 outside the axle sleeve 10 in described bearing seat 3 outsides, rubber seal 2 is the cylindrical shape of an end band shape end face, and the interior astragal of annular end face is the lip circle 12 of projection laterally.Establish the bearing saddle 9 that sinks in the described bearing tight loop 8, perpendicular to axial directionly between bearing saddle 9 and the axle sleeve 10 be connected with many radial fan reinforced ribs 11, also be connected with many radial superpower reinforced ribs 6 between bearing tight loop 8 and the outer wall 7.
Because whole bearing seat outer face is smooth, do not have other block construction, and the face of cylinder of outer face and carrying roller cylinder 5 is excessively smooth, good airproof performance makes the relative splicing structure of anti-dust performance of carrying roller strengthen greatly.Simultaneously be with rubber seal 2 between axle sleeve 10 that protrudes in bearing seat 3 outsides and the roller carrier shaft 1, having stopped dust enters from the slit between roller carrier shaft 1 and the axle sleeve 10, and raised lip circle 12 designs of the inner ring of rubber seal 2, having blocked has the dust and the greasy dirt at counterrotating roller carrier shaft 1 and axle sleeve 10 places directly to enter carrying roller inside.The axle sleeve 10 of bearing seat 3 outside projectioies also plays same dustproof effect.
Because bearing 4 outer rings and bearing tight loop 8 flush fits, and bearing seat 3 links closely with carrying roller cylinder 5 and is one, make bearing 4 outer rings along with carrying roller cylinder 5 rotations, roller carrier shaft 1 is motionless simultaneously, and the bearing seat 4 in-to-in fan reinforced ribs 11 of rotation are in the face of bearing inner ring, and bearing inner ring rotation relatively, play the effect of fan heat-dissipation, cooperate with it, there is diff-H in bearing saddle 9 with axle sleeve 10 inner end surfaces, cooperates the ventilative heat-dissipation effect of playing bearing.6 pairs of carrying roller cylinder inside of superpower reinforced rib between same bearing tight loop 8 and the outer wall 7 and roller carrier shaft 1 play strengthens air flows and heat-dissipation effect.
The total parts are farthest simplified, and designs simplification makes that integral body is dustproof, heat dispersion is better.Guaranteed the steady in a long-term normal running of bearing 4.And its external structure shape and traditional carrying roller do not have big change, and occupation mode does not change yet.
