Abstract
The utility model discloses a side cover fixing device. The side cover fixing device comprises fixing covers (2) and fixing bolts (3), wherein the fixing covers (2) are arranged at the positions, corresponding to side covers (4), of the outer side of a gearbox casing (1), the fixing bolts (3) penetrate into through holes (14) in the fixing covers (2) to enable the fixing covers (2) to be connected with the side covers (4), and the fixing covers (2) are compressed on the gearbox casing (1) through the fixing bolts (3). The side cover fixing device of the structure has the advantages that the displacement, caused by vibration of a pump, of the side covers is reduced, friction inside the device is reduced, breakdowns and damage to the device are reduced, and operating safety and operating smoothness of the device are greatly improved.
Description
Technical field
The utility model relates to a kind of side cover fixing device, relates in particular to a kind of side cover fixing device of two screw pump for high pressure polymerisation reaction cycle that is applicable to.
Background technique
In much machinery, automobile, chemical industry equipment, all relate to the side cover that makes equipment keep relative closure.In the production of vinyl acetate-ethylene copolymerization emulsions, at the polymerisation initial stage to heating material to certain reaction temperature so that material starts polymerisation, when exothermic reaction, take away reaction heat, in recycle system of reaction, be all provided with two screw pump.Between two screw rods of two screw pump, by gear transmission, in gear-box two screw rods end, be equipped with two bearings, for the ease of bearing removal, on gear-box, be provided with two side covers.Pump is in operation and has vibration, and vibration is subjected to displacement side cover, and side cover and screw rod end face rub, and damage screw rod and side cover, produce metal fillings, cause bearing and gear failure; Due to frictional heat, lubricating oil temperature raises, and causes equipment to break down or damages simultaneously.This has greatly destroyed Security and the stationarity of equipment operation.
Model utility content
In view of the foregoing defects the prior art has, the utility model aims to provide the side cover fixing device of a kind of lifting means safety in operation and stationarity.
To achieve these goals, the utility model by the following technical solutions: a kind of side cover fixing device, comprises fixed cover and fixing bolt; Described fixed cover is arranged at the position corresponding with side cover, gear housing outside; Described fixing bolt penetrates the through hole on described fixed cover, and described fixed cover and described side cover are linked together; Described fixing bolt is pressed in described fixed cover on described gear housing.
Preferably, on described fixed cover, be provided with peep hole.
Preferably, described peep hole is provided with two.
A high pressure polymerisation reaction cycle two screw pump, comprises side cover; Described high pressure polymerisation reaction cycle is with being installed on side cover fixing device on two screw pump; Described side cover fixing device comprises fixed cover and fixing bolt; Described fixed cover is arranged at the position corresponding with side cover, gear housing outside; Described fixing bolt penetrates the through hole on described fixed cover, and described fixing bolt end is fixed in the bolt hole on described side cover, and described fixed cover and described side cover are linked together; Described fixing bolt is pressed in described fixed cover on described gear housing.
Compared with the prior art, the utility model has been owing to having adopted technique scheme, reduced side cover because of displacement and the inner friction of device that the vibration of pump produces, reduced fault and the damage of equipment, greatly promoted Security and the stationarity of equipment operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing equipment.
Fig. 2 is the utility model embodiment's structural representation.
Fig. 3 is the plan view of the utility model embodiment fixed cover.
Fig. 4 is the right elevation of the utility model embodiment fixed cover not.
In figure: 1 gear housing, 2 fixed covers, 3 fixing bolts, 4 side covers, 5 screw rods, 6 bearings, 7 fixing bolts, 8 bolts hole, 9 fixed covers, 10 side covers, 11 screw rods, 12 gaps, 13 bearings, 14 through holes, 15 peep holes.
Embodiment
Below by embodiment, the utility model is specifically described; be necessary to be pointed out that at this following examples are only for being further detailed the utility model; can not be interpreted as the restriction to the utility model protection domain, those skilled in the art can make some nonessential improvement and adjustment to the utility model according to foregoing.
Embodiment: a kind of side cover fixing device, as shown in Figures 1 to 4, side cover fixing device comprises fixed cover 2 and fixing bolt 3; Described fixed cover 2 is arranged at the position corresponding with side cover 4, gear housing 1 outside; Described fixing bolt 3 penetrates the through hole 14 on described fixed cover 2, and described fixed cover 2 is linked together with described side cover 4; Described fixing bolt 3 is pressed in described fixed cover 2 on described gear housing 1.
For the ease of the installation of fixing bolt, observe fixed cover simultaneously and whether be subjected to displacement, on described fixed cover 2, be provided with peep hole 15.Described peep hole 15 is advisable to arrange two.
On side cover 4, be provided with bolt hole 8, with the fixing end of fixing bolt 3.
In order to make the gap 12 between fixed cover installation rear bearing and axial end enough large, prevent that bearing and axial end from rubbing, the distance L that should calculate fixing device end face and side cover interior edge face when design fixing device, makes it be greater than the distance T of fixing device end face and bearing exterior edge face.
In use, due to the effect of side cover fixing device, can effectively reduce in high pressure polymerisation reaction cycle with on two screw pump, owing to being two screw pump, two side cover fixing devices that structure is identical are installed conventionally.
