The utility model provides the assembly efficiency of high bolt and fixed structure reduces material loss, has realized the locking effect of better bolt.
Description
Technical field
The utility model belongs to the technical field of fastening of main transmission bearing, particularly a kind of bolt fastening structure of main drive shaft bearing.
Background technique
As shown in Figure 1, existing a kind of main drive shaft bearing 1, this main drive shaft bearing comprises upper pedestal 11 and lower base 12, and the both sides of upper pedestal 11 are the connecting base 111 with screw, for connecting upper pedestal 11 and lower base 12, each connecting base has screwed in a bolt 2, main drive shaft bearing 1 is as the device of frequent forced vibration, high to the installation requirement of fixing bolt 2, just in case bolt 2 gets loose, the generation of work safety accident will be caused, not only bring huge economic loss, even also can threaten the life safety of producers, therefore, main drive shaft bearing 1 often needs the fixed structure preventing bolt 2 from getting loose, bolt fastening structure---the check washer 3 of a kind of main drive shaft bearing in FIG, this check washer 3 is made up of base 31 and three ear seats 32, base 31 is nested with on bolt 2, three ear seats 32 stretch out away from three of base sides respectively, wherein two is relative ear seat 31, bolt 2 side is close to after two relative ear seats upwards extend, another ear seat 32 is close to the sidewall of connecting base 113 after downward-extension, base 31 is coordinated to realize the fastening of bolt 2 by three ear seats 32, but also there is following defect in this bolt fastening structure:
One, two the ear seats 32 being close to bolt 2 side in a pre-installation must maintain an equal level with base, and namely this ear seat can only be close to bolt 2 by manually using instrument to beat after bolt 2 installation, and beat number of times too much, consumable material is many, and installation efficiency is low;
Its two, this bolt fastening structure by means of only check washer 3 one kinds of modes come spacing, anti-loosing effect is unsatisfactory.
In view of this, the bolt fastening structure of the present inventor to main drive shaft bearing improves, and especial manufacture goes out the bolt fastening structure of the main drive shaft bearing that a kind of fixed effect is better, efficiency of assembling is higher, and this case produces thus.
Model utility content
The purpose of this utility model is the bolt fastening structure providing a kind of main drive shaft bearing, to improve efficiency of assembling, reduces spillage of material, reaches better screw retention effect.
To achieve these goals, the technical solution of the utility model is as follows:
The bolt fastening structure of main drive shaft bearing, comprises check washer and locking groove; Described check washer comprises with the base of screw, upper ear seat, lower ear base and middle ear seat, upper ear seat, lower ear base and middle ear seat stretch out from three of base sides respectively, bolt side is close to after upper ear seat upwards extends, lower ear base is close to the side of upper pedestal connecting base after downward-extension, locking groove is formed at main drive shaft bearing top, is close to locking groove bottom surface after the oblique extension of middle ear seat.
Further, described main drive shaft bearing comprises upper pedestal and lower base, and the both sides of upper pedestal are the connecting base with screw, and each connecting base has screwed in a bolt, and locking groove is formed at upper pedestal top.
Further, described locking groove is made up of ramped bottom surface and two side, and middle ear seat corresponding tilt bottom surface is inclined upwardly extension.
After adopting such scheme, during the utility model assembling, check washer is inserted in bolt, lower ear base, middle ear seat can not limit the installation of bolt, therefore lower ear base and middle ear seat when producing with regard to impact briquetting, after bolt screws in screw, lower ear base, middle ear seat directly put in place, only need upper ear seat to beat and be close to bolt side, just can complete installation.
The beneficial effects of the utility model are: it is spacing that the utility model realizes bolt by the upper ear seat of check washer, lower ear base and middle ear seat, guarantee that bolt does not get loose, wherein, middle ear seat coordinates the spacing stability strengthening bolt with the stop flute profile at main drive shaft bearing top, the utility model assembly process is simpler, spillage of material is little, greatly reduces processing and the time of installing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the bolt fastening structure of existing main drive shaft bearing;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is side view of the present utility model;
Fig. 4 is front view of the present utility model.
Label declaration
Main drive shaft bearing 1, upper pedestal 11, connecting base 111, locking groove 112, ramped bottom surface 113, two side 114, lower base 12, bolt 2, check washer 3, base 31, ear seat 32, upper ear seat 321, lower ear base 322, middle ear seat 323.
Embodiment
As shown in Figures 2 to 4, main drive shaft bearing 1 comprises upper pedestal 11 and lower base 12, and the both sides of upper pedestal are the connecting base 111 with screw, and each connecting base 111 has screwed in a bolt 2.
The bolt fastening structure of a kind of main drive shaft bearing that the utility model discloses, comprising:
Check washer 3, check washer 3 comprises with the base 31 of screw, upper ear seat 321, lower ear base 322 and middle ear seat 323, upper ear seat 321, lower ear base 322 and middle ear seat 323 stretch out from three of base sides respectively, upper ear seat 321 is close to bolt 2 side after upwards extending, and lower ear base 322 is close to the side of upper pedestal connecting base 111 after downward-extension;
With locking groove 112, locking groove 112 is formed at main drive shaft bearing top, locking groove 112 bottom surface is close to after the oblique extension of middle ear seat, in the present embodiment, locking groove 112 is formed at upper pedestal 11 top, locking groove 112 is made up of ramped bottom surface 113 and two side 114, and middle ear seat 323 corresponding tilt bottom surface 113 is inclined upwardly extension.
Advantage of the present utility model is: it is spacing that the utility model realizes bolt 2 by the upper ear seat 321 of check washer 3, lower ear base 322 and middle ear seat 323, guarantee that bolt 2 does not get loose, wherein, middle ear seat 323 coordinates the spacing stability strengthening bolt 2 with locking groove 112 shape at main drive shaft bearing top, the utility model assembly process is simpler, spillage of material is little, greatly reduces processing and the time of installing.
Describedly these are only specific embodiment of the utility model, the restriction not to protection domain of the present utility model.All equivalent variations done according to the mentality of designing of this case, all fall into the protection domain of this case.
