Abstract
The utility model relates to a kind of gear locking device for grinding roller of wheat flour-milling sealed bearing housing, comprise nut, bolt and spring washer circle, nut comprises the left-handed nut and right-handed nut that oppositely arrange for a pair, is fixed by a bolt in one end of left-handed nut and right-handed nut.Nut center has a central hair hole, and be laid with some isometrical locking apertures outside the circumference in centrally silk hole, structure and the bolt arrangement of locking aperture match.The utility model solves vibration, friction etc. that the high-speed and continuous running due to grinding roller bearing chamber produces and causes opening nut loosening, locking plate to rupture and then the bearing gear that causes or grinding roller loosens thus locking after causing bearing high temperature, grinding roller drop etc. problem, firmly can lock each rolling bearing on gear and gear, make these lock objects never becoming loose within the routine replacement cycle, reach long-term and stable using effect.
Description
[technical field]
The utility model relates to the Component technical field of industrial installation, specifically a kind of gear locking device for grinding roller of wheat flour-milling sealed bearing housing.
[background technique]
Numerous industrial milling machine on current existing market, as: all there is similar grinding roller bearing chamber in milling machine in raymond mill, pendulum type ring roll pulverizer, Europe version milling machine, trapezoidal milling machine, high pressure pulverizer, roller flour mill etc.
These grinding roller bearing chambers generally adopt traditional opening nut and spring clip locking, but due to grinding roller bearing chamber high-speed and continuous running produce vibration, friction etc., easily cause the reasons such as locking plate fracture, opening nut loosening, and then cause bearing gear or grinding roller loosen thus burn out oil sealing after causing bearing high temperature, powder causes bearing locking, grinding roller drops, shaft of grinding roller rushes the problems such as lid to cause bearing chamber to enter, and causes the losses such as frequent maintenance, replacing, stopping production, overhaul.
[model utility content]
The purpose of this utility model is exactly loosen problem and defect thus locking after causing bearing high temperature, grinding roller drop etc. to solve grinding roller bearing chamber bearing gear or grinding roller, a kind of novel structure, safe and reliable is provided, effectively prevent each rolling bearing of industrial grinding roller of wheat flour-milling bearing chamber and grinding roller sleeve separately gear loosen and the locking device of retaining, comprise nut, bolt and spring washer circle, it is characterized in that described nut comprises the left-handed nut and right-handed nut oppositely arranged for a pair, fixed by a bolt in one end of left-handed nut and right-handed nut.
Described nut center has an axial filament hole, center, and be provided with some isometrical locking apertures outside the circumference in centrally silk hole uniform, locking aperture is identical with the string diameter of bolt.
Locking aperture is silk hole or open-work, and the locking aperture wherein on the nut of lock onto target side is silk hole, otherwise the locking aperture on the nut of opposite side is open-work, and the size in its aperture is greater than string diameter grade of lock(ing) bolt.The reverse nut with a hole is arranged on the inner side of fixing gear, otherwise is fixed on the outside of gear.
Described bolt series high strength bolt, bolt strength >=8.8 grade to be provided with spring washer fastening.
The utility model compared with the existing technology, its advantage is that the utility model solves that vibration, friction etc. that the high-speed and continuous running due to grinding roller bearing chamber produces cause that locking plate ruptures, opening nut loosening and the bearing gear that causes or grinding roller loosens thus locking after causing bearing high temperature, grinding roller drop etc. problem, overcome the drawback of the losses such as frequent maintenance, replacing, stopping production, overhaul, firmly can lock each rolling bearing on gear and gear, make these lock objects never becoming loose within the routine replacement cycle, reach long-term and stable using effect.

As shown in the figure, in figure: 1. left-handed nut 2. right-handed nut 3. bolt 4. grinding roller 5. bearing 6. central hair hole 7. locking aperture 9. shaft of grinding roller;
Fig. 4 is specified to be Figure of abstract of the present utility model.
[embodiment]
Below in conjunction with accompanying drawing, the utility model is described in further detail, and the structure of this device and principle are very clearly concerning the people of this specialty.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, it forms primarily of the upper and lower two left-handed fastening nuts 1 overlapping counter-tightened each other, right-handed nut 2 and bolt 3 composition of the present utility model.The reverse each other big nut of this two cover, except respectively having large central hair hole 6, also have the tightening open-work or silk hole that match with tight fixed bolt, and tightening silk hole and open-work is distributed in the outside in this hole circumferentially same.Because the big nut tightening direction of these two counter-tightened is contrary, so they are worn connection with locked bolt, the tightening effect of these two big nuts mandatory restriction and never becoming loose each other just can be played.
This two cover big nut 1 and 2 reverse each other as shown in Figure 3, Figure 4, is given tightening after conventional degree of tightness oil clearance adjusted by the bearing 5 on shaft of grinding roller 9 top, is then locked by these two big nuts by bolt 3 by concrete installation of the present utility model.Easily bolt 3 can be loosened during dismounting after taking out, the more reverse nut 1 and 2 of turn can unlock one by one.
