Abstract
The utility model discloses a minor diameter cylinder for band conveyer, this minor diameter cylinder include fixed axle, axle with jump ring and a plurality of deep groove ball bearing, a plurality of deep groove ball bearing are flat row in proper order and are located the fixed axle outer lane, the axle is located with the jump ring the fixed axle both ends and the clamp are located a plurality of deep groove ball bearing of fixed axle outer lane. The roller overcomes the defects of the traditional small-diameter roller, is convenient to manufacture and install, reduces the machining precision requirement of parts, saves the manufacturing cost, and effectively prolongs the service life of the small-diameter roller.
Description
Technical Field
The utility model relates to a commodity circulation technical field especially relates to a minor diameter cylinder for band conveyer.
Background
In the prior art warehouse logistics equipment, belt conveyors have been widely used, and in some specific occasions, rollers with small diameters (usually less than 40 mm) are often used as end rollers of the belt conveyors.
The existing small-diameter roller is generally formed by combining a fixed shaft, a roller body and a bearing, wherein the fixed shaft is arranged on an inner ring of the roller body through the bearing, so that the requirements on the processing precision of the roller body and the fixed shaft are quite high, and the limitation on the selection of the bearing is large in order to meet the requirement on the small diameter. This often results in a drum with low strength, short service life, and difficult installation and processing. In particular, during the installation of the bearing, damage to the bearing is often caused. The manufacturing cost of the small-diameter drum is increased.
Disclosure of Invention
The utility model aims to solve the technical problem that a minor diameter cylinder for band conveyer is provided, traditional minor diameter cylinder's defect is overcome to this cylinder, and its preparation, simple to operate reduce the machining precision requirement of spare part, save the cost of manufacture, effectively improve this minor diameter cylinder's life.
In order to solve the technical problem, the utility model discloses a minor diameter cylinder for band conveyer includes fixed axle, for the axle jump ring and a plurality of deep groove ball bearing, a plurality of deep groove ball bearing are arranged in parallel in proper order and are located fixed axle outer lane, the jump ring is located for the axle the fixed axle both ends and the clamp are located a plurality of deep groove ball bearing of fixed axle outer lane.
Furthermore, the deep groove ball bearings are in interference fit with the fixed shaft.
Furthermore, clamping grooves are formed in the two ends of the fixing shaft in the circumferential direction respectively, and the shaft clamping springs are arranged in the clamping grooves and abut against the end faces of the outer deep groove ball bearings in the plurality of deep groove ball bearings.
Because the utility model discloses a minor diameter cylinder for band conveyer has adopted above-mentioned technical scheme, this minor diameter cylinder includes that fixed axle, axle are with jump ring and a plurality of deep groove ball bearing promptly, a plurality of deep groove ball bearing are flat row in proper order and are located the fixed axle outer lane, the jump ring is located for the axle the fixed axle both ends and the clamp is located a plurality of deep groove ball bearing of fixed axle outer lane. The roller overcomes the defects of the traditional small-diameter roller, is convenient to manufacture and install, reduces the machining precision requirement of parts, saves the manufacturing cost, and effectively prolongs the service life of the small-diameter roller.
Drawings
The invention will be described in further detail with reference to the following drawings and embodiments:
fig. 1 is a schematic structural view of a small-diameter roller for a belt conveyor according to the present invention.
Detailed Description
Embodiment is shown in fig. 1, the utility model discloses a minor diameter cylinder for band conveyer includes fixed axle 1, for the axle jump ring 2 and a plurality of deep groove ball bearing 3, a plurality of deep groove ball bearing 3 are flat row in proper order and are located 1 outer lane of fixed axle, jump ring 2 is located for the axle 1 both ends of fixed axle and the clamp is located a plurality of deep groove ball bearing 3 of 1 outer lane of fixed axle.
Preferably, the plurality of deep groove ball bearings 3 are in interference fit with the fixed shaft 1.
Preferably, the two ends of the fixed shaft 1 are respectively provided with a clamping groove 11 along the circumferential direction, and the snap spring 2 for the shaft is arranged in the clamping groove 11 and is abutted against the end surfaces of the outer deep groove ball bearings in the plurality of deep groove ball bearings 3.
The small-diameter roller completely changes the manufacturing process of the original roller, after a fixed shaft is machined and clamping grooves are turned at two ends of the fixed shaft, a snap spring is installed at one end of the fixed shaft, then a deep groove ball bearing is heated (a hot sleeve method), an inner ring of the bearing is sequentially sleeved into an outer ring of the fixed shaft after being heated and expanded, the deep groove ball bearing is in interference fit with the fixed shaft after being cooled, a plurality of deep groove ball bearings are firmly fixed on the shaft, and finally the snap spring is installed at the other end of the fixed shaft, so that the small-diameter roller is.
Because the deep groove ball bearing is installed by adopting a hot sleeve method, the installation is convenient, the bearing is not damaged, and the requirement on the processing precision of the fixed shaft is relatively low. And because a plurality of independent deep groove ball bearings are arranged on the fixed shaft to form the small-diameter roller, when one bearing is damaged, the use of the whole roller is not influenced, and the service life is effectively prolonged. This minor diameter cylinder directly adopts a plurality of deep groove ball bearings to be the cylinder barrel, compares in current cylinder structure, and the bearing model that can select to use is more, and bearing long service life, and is not fragile, and this minor diameter cylinder compares the cylinder that comprises fixed axle, barrel and bearing combination and has bigger advantage, satisfies the demand that band conveyer end cylinder was used completely.
