Abstract
A fastening and detaching device for driving axle adjusting nuts comprises a disc base, stepped pins, an adjusting nut and a hexagonal head, wherein the hexagonal head is arranged in the center of the disc base, the three stepped pins are mounted on the disc face of the disc plate, projections at the rear ends of the stepped pins are arranged in a groove of the adjusting nut, and the disc base is provided with two crossing through holes. By adopting the structure, the adjusting nut is convenient to rotate when the fastening and detaching device is used in fastening and detaching operations of the adjusting nut, axial clearance of a bearing at a driving axle differential end can be adjusted properly conveniently according to the relation of thread pitch of the adjusting nut to the bearing, and no damage can be done to any part.
Description
Technical field
The utility model relates to the tightening and loosening device that a kind of drive axle is adjusted nut.
Background technology
Drive axle is adjusted nut and is installed on the drive axle main reducing gear assembly, and main effect is an end-play of adjusting the taper roll bearing of differential mechanism end, and bearing is carried out spacing, prevents its axial play.Drive axle is adjusted nut and is different from plain nut, and it is that a foundry goods forms through machined, and outer surface has many equally distributed slotted channel, and thread size is bigger, and is external screw thread.Drive axle is as the drive disk assembly of complete machine, and work is frequent, and operating mode is abominable, often needs maintaining, adjusts nut as adjusting element, often needs fastening and dismounting especially.Owing to adjust the structure particularity of nut, also there is not a kind of proper tools to carry out fastening to it and dismounting now, only realize adjusting the fastening and dismounting of nut to adjusting beaing of nut groove shape ditch trough rim by pole, iron hammer.Realize adjusting the fastening of nut by beaing, be not easy to adjust the end-play of differential mechanism end bearing, be difficult to play and adjust the due corrective action of nut, adjusting nut simultaneously is foundry goods, and hardness is not high, beats operation repeatedly, and easy deformation is damaged.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, adjust the device of nut not damaging the tightening and loosening drive axle that is convenient to adjust differential mechanism end bearing end-play under the situation of adjusting nut.
The purpose of this utility model is achieved in that and comprises disc seat, ladder pin, adjustment nut, six square toes, there is six square toes at the center of disc seat, three ladder pins are installed on the card of disc seat, and the projection of ladder pin rear end is in the slotted channel of adjusting nut.
The through hole that two intersections are arranged on the described disc seat.
Because the utility model adopts said structure, use this device to adjust in the nut operation in fastening, dismounting, it is convenient to adjust the nut rotation, according to the pitch of adjusting nut thread and the relation of bearing end-play, easily just the end-play of drive axle differential mechanism end bearing is adjusted to the right place, do not damage any part simultaneously again.
Description of drawings
Fig. 1 is the structure chart of the utility model embodiment.
Fig. 2 is the left TV structure figure of Fig. 1.
1 disc seat, 2 ladder pins, 3 are adjusted nut, 4 six square toes, 5 through holes, 6 projections among the figure.
The specific embodiment
Embodiment: this device comprises disc seat 1, ladder pin 2, adjusts nut 3, six square toes 4, there is six square toes 4 at the center of disc seat 1, three ladder pins 2 are installed on the card of disc seat 1, the projection 6 of ladder pin 2 rear ends is in the slotted channel of adjusting nut 3, and last two through holes 5 that intersect are up and down arranged on the disc seat 1.
There is six square toes 4 top of disc seat 1, and instruments such as cross sleeve, open-end wrench can act directly on six square toes 4.The projection 6 that 2, three ladder pins 2 of three ladder pins are installed on the card of disc seat 1 all is on the slotted channel of adjusting nut 3, drives adjustment nut 3 by ladder pin 2 when disc seat 1 rotates and rotates, thereby realize adjusting the fastening of nut 3 and dismounting.The through hole 5 that two intersections are arranged on the disc seat 1 if do not have instruments such as cross sleeve, open-end wrench at one's side, also can partly stretch in the through hole 5 with an iron staff during operation, prizes disc seat 1 and rotates, thereby can realize adjusting the fastening of nut 3 and dismounting.When adjustment nut 3 rotates a circle on fastening direction, and the gap between the drive axle differential mechanism end bearing reduces the size of a pitch; When on disassembly direction, rotating a circle, and the gap between the drive axle differential mechanism end bearing increases the size of adjusting a pitch of nut 3 external screw threads, calculates the number of turns of described adjustment nut 3 required rotations according to drive axle differential mechanism end bearing end-play.Six square toes 4 or through hole 5, utilize instruments such as cross sleeve, open-end wrench, iron staff, easily drive and adjust nut 3 rotations, realize the fastening of described adjustment nut 3 and dismounting, the end-play of adjusting drive axle differential mechanism end bearing is very convenient, and need not to beat any part in the operating process, can not damage any part.
Claims (2)
1. a tightening and loosening drive axle is adjusted the device of nut, comprise disc seat, ladder pin, adjust nut, six square toes, it is characterized in that: there is six square toes at the center of disc seat, and three ladder pins are installed on the card of disc seat, and the projection of ladder pin rear end is in the slotted channel of adjusting nut.
2. a kind of tightening and loosening drive axle according to claim 1 is adjusted the device of nut, it is characterized in that: the through hole that two intersections are arranged on the described disc seat.
