Abstract
The utility model provides a roller chain tension device which comprises a support, a screw rod and a sliding block. A sliding groove is formed in the support. The sliding block is arranged in the sliding groove. One end of the screw rod is fixed on the support, and the other end of the screw rod penetrates through the sliding block. The upper end of the screw rod and the lower end of the screw rod are respectively provided with an adjusting nut. A tensioner sprocket is supported on a pin shaft through a bearing, wherein the pin shaft is arranged on the upper portion of the sliding block. The tensioner sprocket is supported by the sliding block. The sliding block can continuously slides in the sliding groove of the support. The tensioner sprocket can be fixed at a required height by adjusting a screw rod mechanism, and continuous adjustment of tension degree of the chain can be achieved.
Description
Technical field
The utility model relates to the simple chain tensioning apparatus in the mill table transmission equipment, is used for the chain tension degree on free adjustment milling train transmission roller channel.
Background technology
In the milling train transmission equipment, chain stretching device is used for regulating the chain tension degree of transmission roller channel equipment, thereby makes the steady and continuous running of transmission roller channel, realizes the transmission of stocking supplied materials and finished product.
There is certain shortcoming in existing milling train transmission roller channel chain drive, chain produces wearing and tearing at work, and cause the harmful effects such as chain is lax, sagging, need to carry out at any time the tensioning adjustment, generally extract with chain direct effect external force by chain assemblies and adjust, working strength and adjustment difficulty are large, complex structure.
Whether have elastic component and tensioning apparatus commonly used at present can be divided into two kinds of elastic stretching device and rigidity tensioning apparatus according to the tensioning principle, realize the running that transmission roller channel is steady and continuous, can only select the rigidity tensioning apparatus.
The utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of simple chain tensioning apparatus is provided, and the chain that is applicable to various transmitting devices in milling train is regulated.
The purpose of this utility model is achieved through the following technical solutions:
The roller chain tensioning apparatus, characteristics are: comprise support, screw mandrel and slide block, described support is provided with chute, slide block is placed in chute, one end of screw mandrel is fixed on support, the other end of screw mandrel passes slide block, and it is respectively equipped with an adjusting nut up and down, and tightener sprocket is bearing on the bearing pin that is arranged at slide block top by bearing.
Further, above-mentioned roller chain tensioning apparatus, an end of described screw mandrel is the homalocephalus shape, inserts in the flat hole of support fixing.
The substantive distinguishing features that technical solutions of the utility model are outstanding and significant progressive being mainly reflected in:
By the thrust slide supporting tightener sprocket, slide block can slide in bracket chute continuously, by adjusting the height that screw body can be fixed on tightener sprocket to be needed, has realized the continuous adjusting to the chain tension degree.Remarkable advantages such as having compact conformation, save the space, be easy to adjust.
Description of drawings
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Fig. 1: master of the present utility model looks schematic diagram;
Fig. 2: schematic side view of the present utility model;
The A-A cross-sectional schematic of Fig. 3: Fig. 2.
The specific embodiment
as Fig. 1, shown in Figure 2, the roller chain tensioning apparatus, comprise support 1, screw mandrel 6 and slide block 2, support 1 is the general assembly basis of tensioning apparatus, be fixed on the basis by fastener, support 1 is provided with chute, slide block 2 is placed in chute, slide block 2 can slide up and down in the chute of support 1, one end of screw mandrel 6 is the homalocephalus shape, insert in the flat hole of support 1 fixing, the other end of screw mandrel 6 passes slide block 2, it is respectively equipped with an adjusting nut 7 up and down, tightener sprocket 3 is bearing on the bearing pin 4 that is arranged at slide block top by bearing 9, as shown in Figure 3, bearing pin 4 is installed on slide block 2, axle sleeve 10 and bearing 9 are installed on bearing pin 4, tightener sprocket 3 is installed in bearing 9 outer rings, transparent cover 8 is fixed on tightener sprocket 3, and compress bearing 9 outer rings, the two ends of bearing pin 4 are compressed by pressing plate 5, coordinate with roller chain with tightener sprocket and carry out transmission, make the transmission effect of roller chain can not be affected.
Chain is lax when needing tensioning, one end of screw mandrel 6 is inserted in the hole of support 1 and maintains static, adjust two adjusting nuts 7 of the other end of screw mandrel 6, then adjusting nut above first adjusting, screws following adjusting nut, slide block 2 is moved on chute, drive on tightener sprocket 3 and move, the extruding chain, thus make the chain tension.Otherwise, adjust adjusting nut 7, drive tightener sprocket 3 and move down, make chain lax.Accurate location by slide block and chute and screw mandrel coordinate with tension part, realize that tension part can swing when sliding up and down, thereby have guaranteed that tightener sprocket can stably contact with chain.
The height of the relative support of slide block is adjusted by screw mandrel and adjusting nut, the setting of slide block structure and the use of screw structure realize that the relative altitude between slide block and support can regulate continuously, thereby the height of tightener sprocket is regulated continuously, realized the continuous adjusting to the chain tension degree.
In sum, the setting of slide block structure makes the tensioning apparatus overall structure compact, has saved the space; The use of screw mandrel, nut makes the height of tightener sprocket to adjust arbitrarily, thereby has guaranteed the continuous adjusting of chain tension degree; Adjusting nut gets final product the adjusting chain tightness, regulates very convenient.
What need to understand is: the above is only preferred embodiment of the present utility model; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
