Abstract
The utility model discloses a lock device used for a rotary part. The lock device comprises the rotary part which is provided with a center hole and a rotating shaft which is arranged in the center hole and is provided with a key groove, wherein a lock mechanism which is matched with the key groove and is connected with the rotating shaft is arranged at one end of the center hole, the lock mechanism comprises a lock baffle, a lock sheet and a fixing bolt, an inserting port and an installing hole are arranged on the lock baffle, the lock sheet comprises a lock sheet body which is provided with a fixing hole in the middle, a fixed bending plate and a stop plate which is matched with the key groove through the inserting port are arranged on the lock sheet body, the fixing bolt is in thread connection with the rotating shaft through the fixing hole and the installing hole, and the head part of the fixing bolt is arranged on the fixed bending plate. With the adoption of the lock device, bigger axial force can be born, the rotary part can be prevented from moving outwards along the axial direction, the security coefficient is extremely high, the installation is convenient, and the work efficiency is high.
Description
Technical field
The utility model relates to a kind of locking device, particularly a kind of locking device that is used for rotary component.
Background technique
At present; The locking device of known rotary component adopts is single ear anti-motion washer (GB/T854) and the lock washer with double ears (GB/T855) etc. in the mechanical design handbook; Axially strength is less, may produce rotary component and meet axially outside moving, and safety coefficient is not high; The lock washer with tongue at outside (GB/T856) that adopts in the mechanical design handbook, screw fastening shaft end baffle ring (GB/T891, GB/T892), diplopore shaft end ring (JB/ZQ4349), axle head locked spacer (JB/ZQ4347) etc. are also arranged; They need boring once more to install; Comparatively inconvenience is installed, and working efficiency is low.
The model utility content
The purpose of the utility model is, a kind of locking device that is used for rotary component is provided.The utility model can not only bear bigger axial force, avoids rotary component to meet axially and outwards moves, and safety coefficient is high, and easy for installation, and working efficiency is higher.
The technological scheme of the utility model: the locking device that is used for rotary component; Comprise the rotary component that has center hole and be arranged in the center hole and have the rotating shaft of keyway; One end of said center hole is provided with and locking mechanism that with rotating shaft be connected that cooperate with keyway, it is characterized in that: described locking mechanism comprises locking baffle plate, lock sheet and fixing bolt, and the locking baffle plate is provided with socket and mounting hole; Lock sheet comprises that the middle part has the locking plate body of fixed hole; The locking plate that the locking plate body is provided with fixing bending sheet and cooperates with keyway through socket, fixing bolt is threaded with rotating shaft through fixed hole, mounting hole, and the head of fixing bolt fixedly is set on the bending sheet.
The aforesaid locking device that is used for rotary component, described fixedly bending sheet be two arranged in a crossed manner.
The aforesaid locking device that is used for rotary component, described socket are the square mouths.
Compared with prior art, the utility model reaches the purpose of anti-sliding stop through locking plate is inserted in the keyway, bears bigger axial force through the locking baffle plate, avoids rotary component to meet axially and outwards moves, and improves safety coefficient, and is safe and reliable; And when mounted fixing bolt is got final product with being threaded of rotating shaft, easy for installation, improved working efficiency.The utility model is safe and reliable, installs simply, can realize mold, seriation making very easily, drops into worker, the people in enormous quantities, builds use.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the application schematic representation of the utility model.
Being labeled as in the accompanying drawing: the 1-rotating shaft, the 2-keyway, the 3-rotary component, the 4-socket, 5-locks baffle plate, the 6-locking plate, 7-fixing bolt, 8-be the bending sheet fixedly, 9-lock sheet, 10-mounting hole, 11-center hole.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.The locking device that is used for rotary component; Constitute as shown in Figure 1; Comprise the rotary component 3 that has center hole 11 and be arranged in the center hole 11 and have the rotating shaft 1 of keyway 2; One end of said center hole 11 is provided with and keyway 2 cooperate and locking mechanisms that be connected with rotating shaft 1, and it is characterized in that: described locking mechanism comprises locking baffle plate 5, lock sheet 9 and fixing bolt 7, and locking baffle plate 5 is provided with socket 4 and mounting hole 10; Lock sheet 9 comprises that the middle part has the locking plate body of fixed hole 12; The locking plate 6 that the locking plate body is provided with fixing bending sheet 8 and cooperates with keyway 2 through socket 4, fixing bolt 7 is threaded with rotating shaft 1 through fixed hole 12, mounting hole 10, and the head of fixing bolt 7 fixedly is set on the bending sheet 8.
More excellent is, described fixedly bending sheet 8 be two arranged in a crossed manner; Described socket 4 is square mouths.
The utility model is used as shown in Figure 2; Described rotating shaft is inserted in the center hole of rotary component; Be connected with rotating shaft through flat key, then the locking plate on the lock sheet passed socket and insert keyway inside, be threaded with the rotating shaft screwed hole of centre through fixed hole, mounting hole with fixing bolt again; Tighten the back and embrace the hexagon-head of fixing bolt, get final product with fixing bending sheet.
The utility model reaches the purpose of anti-sliding stop through locking plate is inserted in the keyway, bears bigger axial force through the locking baffle plate, avoids rotary component to meet axially and outwards moves, and improves safety coefficient, and is safe and reliable; And when mounted fixing bolt is got final product with being threaded of rotating shaft, easy for installation, improved working efficiency.The utility model is safe and reliable, installs simply, can realize mold, seriation making very easily, drops into worker, the people in enormous quantities, builds use.
