Embodiment
Describe below in conjunction with the technological scheme of accompanying drawing model utility.
As shown in Figure 1, 2, in order to address the above problem, a kind of belt wheel tension device of the present utility model, include chain 6, Idle wheel 5, main shaft 1 and regulate base 7, described chain 6 is connected with first driving mechanism, second driving mechanism respectively, described Idle wheel 5 is arranged between first driving mechanism and second driving mechanism, and described main shaft 1 is by bearing 8 and described Idle wheel 5 pivot bush units, and described main shaft 1 one ends are fixedlyed connected with described adjusting base 7.Therefore, between first driving mechanism and second driving mechanism, Idle wheel 5 is set, when chain 6 elongated lax after, by regulating main shaft 1 and regulate the relative position of base 7, thereby reach the purpose of tension chain 6.
Described Idle wheel 5 is provided with chain 51, and chain 6 is positioned at described chain 51, and chain can not run out of because of play when transmitting like this.
Described Idle wheel 5 centers are provided with bearing support 52, and described bearing support 52 has annular groove 521, and described bearing 8 is provided with snap ring 81, described annular groove 521 and described snap ring clamping.
In the present embodiment,, can not drive Idle wheel 5 when needing to guarantee main shaft 1 rotation and move because main shaft 1 passes through bearing 8 and Idle wheel 5 pivot bush units.Described main shaft 1 two ends are provided with screw thread, and it is fastening to be equipped with nut during installation.Wherein, the screw thread tightening direction of described main shaft 1 must be identical with the traffic direction of chain 6, otherwise the main shaft 1 of Idle wheel 5 can move back silk automatically and falls down after operation a period of time.
Described main shaft 1 corresponding bearing 8 positions are provided with bearing screens 82, snap ring 81 clampings of described bearing screens 82 and bearing, thus guarantee that main shaft firmly is connected with bearing.When main shaft 1 is installed, bearing 8 is rushed out when preventing that main shaft 1 from passing bearing core, needed in a side of Idle wheel 5 bearing 8 to be installed earlier described bearing 8 and these side shaft holder 52 clampings, then main shaft 1 is passed Idle wheel 5, the bearing 8 of Idle wheel 5 opposite sides is installed again.Because main shaft 1 is provided with bearing screens 82, the snap ring 81 and described screens 82 clampings of described bearing.At this moment, Idle wheel 5 is finished with main shaft 1 assembling.
In the present embodiment, described adjusting base 7 is provided with screw 71, and described main shaft 1 outer end is provided with the screw thread of coupling, and described main shaft 1 passes described screw 71 fixedlys connected with adjusting base 7.Can regulate the installation of base according to tensioning adjustment mode, the tensioning mode can be tensioning again after progressively tensioning or equipment stop according to the equipment operation situation.Because the separation machine has the running clearance time, tensioning again after employing equipment stops, therefore, concrete, described adjusting base 7 can be an iron plate, described adjusting base 7 width directions have a long strip screw hole 72, and this screw hole 72 is used to regulate the mobile position of main shaft 1, thereby regulate the purpose that Idle wheel 5 reaches tension chain 6.
Further, be provided with gap 9 between described Idle wheel and the adjusting base, thereby this gap 9 has avoided Idle wheel and adjusting base generation friction to cause wearing and tearing.
Therefore, adopt the belt wheel tension device of said structure, reduced the friction of chain, increased its working life, solved chain and driving gear and mistake occurred and refute tooth, caused equipment play, damage, can make the problem of chain fracture when serious, thereby guaranteed the stable operation of equipment work, especially changed the tensioning mode of the chain of the equipment of fixed conveyor mode and double-stranded transmission device.
