Abstract
The utility model discloses an accumulation roll which comprises a roll shaft, a roller, and a chain wheel mounted on the roll shaft, wherein the roll shaft is sleeved with the roller; bearing assemblies are arranged at the two ends of the roller; a friction piece is arranged between the chain wheel and one bearing assembly; an adjustment device for adjusting friction between the roller and the chain wheel is arranged on the roll shaft, and comprises an adjustment nut and a spring; the spring is provided with a fixed end and a free end; the free end of the spring is connected with the bearing assembly close to the chain wheel in a push-against manner; and the adjustment nut is arranged at one end of the roll shaft where the chain wheel is mounted. The accumulation roll is compact in structure and stable in adjustment process.
Description
Technical field
The utility model relates to a kind of free parking type roller.
Background technology
The article that the free parking type roller is widely used in the industries such as food, postal service, auto parts and components, operating line have on the roller conveyor that stops and accumulating, the free parking type roller comes the size of regulating friction force by the amount of compression of regulating spring, be to reserve certain-length at the roller axle end in prior art, be used for mounting spring and setting nut.Yet the roller axle end has more the position of one section mounting spring, increases the length of whole roller, has taken additional space, and because spring fitting positional distance sprocket wheel is far away, easily occurs the phenomenons such as chain and sprocket wheel latch or jumping tooth during adjusting.
Summary of the invention
Technical problem to be solved in the utility model just is to provide compact conformation, a kind of free parking type roller of control process pulsation-free.
for solving the problems of the technologies described above, the utility model adopts following technical scheme, a kind of free parking type roller, comprise roll shaft, be enclosed within the roller on roll shaft and be installed on sprocket wheel on roll shaft, the two ends of described roller are provided with bearing assembly, be provided with friction member between described sprocket wheel and bearing assembly, described roll shaft is provided with the control apparatus of friction force between adjusting roller and sprocket wheel, described control apparatus comprises setting nut and spring, described spring has fixed end and free end, its free end is connected near on the bearing assembly of sprocket wheel one side, described setting nut is located at the end that roll shaft is installed sprocket wheel.
Preferably, described friction member slidably is socketed on roll shaft.
Preferably, described friction member is fixed on bearing assembly or sprocket wheel.
Preferably, described friction member is friction ring or friction lining.
Preferably, described roller bearing is provided with the shaft shoulder, and described spring one end is against and forms described fixed end on the shaft shoulder.
The setting nut of a kind of free parking type roller that the utility model provides and spring are installed an end of sprocket wheel at described roll shaft, take full advantage of the space on described roll shaft, and because spring, setting nut and sprocket wheel are installed compact, the phenomenons such as chain and sprocket wheel latch or jumping tooth can not occur when regulating, regulate steadily.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a kind of free parking type roller structure of the utility model schematic diagram.
The specific embodiment
as shown in Figure 1, be a kind of free parking type roller of the utility model, comprise the roll shaft 2 of being located on frame 1, be enclosed within the roller 3 on roll shaft 2 and be installed on sprocket wheel 4 on roll shaft 2, the two ends that described roller is 3 are provided with bearing assembly 5, be provided with friction member 6 between described sprocket wheel 4 and bearing assembly 3, described roll shaft 2 is provided with the control apparatus of friction force between adjusting roller 3 and sprocket wheel 4, described control apparatus comprises setting nut 7 and spring 8, described spring 8 has fixed end and free end, its free end is connected near on the bearing assembly 3 of sprocket wheel 4 one sides, described setting nut 7 is located at the end that roll shaft 2 is installed sprocket wheel 4.
Rotate described setting nut 7, described spring 8 further compresses, and the pressure that is applied on described friction member 6 becomes large, and it is large that friction force becomes.When needing less friction force, oppositely regulate described setting nut 7 and get final product.
In present embodiment, described friction member 6 is friction ring, and described friction ring slidably is socketed on roll shaft 2, during installation, described friction ring is enclosed within on described roll shaft 2 gets final product.Described friction member 6 also can be fixed on described bearing assembly 5 or described sprocket wheel 4 by lamella whole with ring-type or several arbitrary shapes, is not limited in the above-mentioned specific embodiment.
Described roller bearing 2 is provided with the shaft shoulder 21, and described spring 8 one ends are against and form described fixed end on the shaft shoulder 21.
Can also adopt other structures to be used for keeping the invariant position of fixed end on described roll shaft 2 of described spring 8 to get final product, as: projection cube structure or other structures that can be provided with projection.
In present embodiment, also be provided with pad 9 between described spring 8 and described bearing assembly 5.
Described pad 9 makes described spring 8 and described bearing assembly 5 indirect contacts, avoids wearing and tearing between described spring 8 and described bearing assembly 5, and raising product service life.
