Description
Technical field
The utility model is specifically related to a kind of linkage structure of helical rotor pump bottom bracket, the bearing support linkage structure of the detachable bearing formula of particularly a kind of helical rotor pump.
Background technique
It is a deficiency of screw pump that bearing in the existing helical rotor pump bottom bracket can not be changed.Because transmission shaft is that the fourth of the twelve Earthly Branches is gone in the bearing, and bearing to be the fourth of the twelve Earthly Branches equally go in the bearing support, when damage of bearings, if bearing is taken out from bearing support then can damage bearing support, bearing support just can not re-use, and has so not only increased the difficulty of changing, and has increased the user cost of enterprise simultaneously.And bearing support making again, bearing is installed again, waste time and energy.
Summary of the invention
The utility model provides the bearing support linkage structure of the detachable bearing formula of a kind of helical rotor pump, purpose is to solve existing issue, a kind of linkage structure that can conveniently bearing be disassembled from bearing support is provided, this linkage structure can not be destroyed bearing support when changing bearing, and the replacing process is simple, and is time saving and energy saving.
The utility model technological scheme that adopts of dealing with problems is:
The bearing support linkage structure of the detachable bearing formula of helical rotor pump has bearing support, and bearing is located in the bearing support, and the transmission shaft of helical rotor pump is located in the bearing.Bearing support has the concentric pylone of two different-diameters, and the diameter of large through-hole is identical with the external diameter of bearing, and the diameter of small through hole is identical with the diameter of transmission shaft.The bearing cap opening end has step, and step is provided with screw, and its bearing cap opening end contact is on bearing, and bolt passes that screw is screwed into the screw that is located on the bearing support and is arranged in the large through-hole both sides on the step, and bearing cap and bearing support are fixed together.Described transmission shaft is established in the bearing by bearing core, and bearing core one end has outside thread, and this outside thread one end matches with the screw that transmission shaft is provided with.Bearing core has an externally threaded end and passes bearing and with the screwhole spiro bonding of transmission shaft together, and transmission shaft, bearing, bearing core are fixed together.
On bearing support and be positioned at the small through hole both sides and be respectively equipped with the inner bolt hole that is communicated with large through-hole, screw in the dismounting screw in the inner bolt hole.
The beneficial effects of the utility model: the combination of transmission shaft and bearing is screwed into by bearing core in the screw of transmission shaft it is fixed together in this structure, only transmission shaft need be separated getting final product when transmission shaft is separated with bearing with bearing core.Bearing then is clamped in it in bearing support fixing by dismounting screw and bearing cap opening end, bearing only need now be taken off bearing cap when bearing support disassembles, and screws the dismounting screw again and bearing is ejected from bearing support gets final product.Installation process is opposite with dismounting, and the whole erection unloading process is simple, bearing and bearing support can not damaged simultaneously, and bearing support can re-use, and has not only reduced user cost, and is simultaneously time saving and energy saving.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The bearing support linkage structure of the detachable bearing formula of helical rotor pump as shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 has bearing support 1, and bearing 2 is located in the bearing support 1, and the transmission shaft 3 of helical rotor pump is located in the bearing 2.Bearing support 1 has the concentric pylone of two different-diameters, and the diameter of large through-hole 4 is identical with the external diameter of bearing 2, and the diameter of small through hole 5 is identical with the diameter of transmission shaft 3.Bearing cap opening end 6 has step 7, step 7 is provided with screw 8, its bearing cap opening end 6 contacts are on bearing 2, and bolt passes that screw 8 is screwed into the screw 9 that is located on the bearing support 1 and is arranged in large through-hole 4 both sides on the step, and bearing cap 10 and bearing support 1 are fixed together.Wherein transmission shaft 3 is established in the bearing 2 by bearing core 11, and bearing core 11 1 ends have outside thread, and this outside thread one end matches with the screw 12 that transmission shaft 3 is provided with.Bearing core 11 has an externally threaded end and passes bearing 2 and be screwed on together with transmission shaft screw 12, and transmission shaft 3, bearing 2, bearing core 11 are fixed together.For convenient bearing 2 is taken out from bearing support 1, on bearing support 1 and be positioned at small through hole 5 both sides and be respectively equipped with the screw 13 that is communicated with large through-hole 4, screw in the screw 13 and dismantle screw 14.
Bearing Installation is as described below to the process in the bearing support: as shown in Figure 5, bearing core 11 to be had outside thread one end pass bearing 2 and be screwed in the screw of transmission shaft 12, bearing core 11, bearing 2, transmission shaft 3 are fixed together.Then as shown in Figure 6, the bearing core 11, bearing 2, the transmission shaft 3 that link together are put into bearing support 1, transmission shaft 3 passes the small through hole 5 in the bearing support, and bearing 2 is inserted in the large through-hole 4.Again as shown in Figure 7, bolt passed the screw 8 on the bearing cap step 7 and be screwed into the screw 9 of bearing support large through-hole both sides, bearing cap 10 and bearing 2 are fixed together, bearing cap opening end 6 contacts are on bearing 2.To dismantle at last in the screw 13 that screw 14 is screwed into bearing support small through hole both sides, dismounting screw 14 top contacts are on bearing 2, and mounted overall structure as shown in fig. 1.
Dismounting is taken off bearing cap 10 earlier, transmission shaft 3 is separated with bearing core 11 again, screws dismounting screw 14 at last, with dismounting screw 14 bearing 2 is ejected from bearing support 1.
In fact also can not need to dismantle screw 14 in this linkage structure, it is insecure just not dismantle screw 14 its overall structures, absent-mindedness easily between bearing 2 and the bearing support 1 in the course of the work, and then produce danger, the while is inconvenience when the dismounting bearing.
The whole erection unloading process is simple, bearing and bearing support can not damaged simultaneously, and bearing support can re-use, and has not only reduced user cost, and is simultaneously time saving and energy saving.
