Description
Technical field
This utility model relates to a kind of automobile fitting device, particularly relates to a kind of automotive tyre nut pre-tightening apparatus.
Background technology
Auto industry is extensively applied threaded, and general car uses threaded quantity to be about 3500.Important zero
The assembling of parts, if automobile tire is with threaded, during assembling, does not require nothing more than work efficiency high, and to assembling matter
Measure such as screwing force, moment of torsion etc. and have required precision, if moment of torsion is excessive, seriously exceed the yield limit of threaded connector material,
Screw thread fracture will be made, lost efficacy or fastened unsuccessfully.During automobile uses, people to the replacement frequency of automobile tire also from
The minimizings in 5 years started, to present 2.5 years, decrease one times.Automobile industry in some developed regions has developed very
Maturation, the replacement cycle of their tire is not more than 2 years.Therefore, whether automobile tire assembling and tyre service are changed,
It is required for efficiency height, the measured installation tool of matter.The present invention uses gear drive, carries out pre-to automobile tire the most simultaneously
Tight dress, the most not only work efficiency is high, and ensures that each threaded screwing force equalizes.Simple in construction, it is simple to carry and grasp
Use.
Summary of the invention
The purpose of this utility model is to provide a kind of automotive tyre nut pre-tightening apparatus, this device driving gear and little tooth
Wheel is in engagement, and handle rotates and drives master gear to rotate, and is delivered to little gear, and sleeve rotates simultaneously, the most permissible
The multiple lug nut of pretension simultaneously, it is achieved tyre pretightening, improves the work efficiency of pretension lug nut.
The purpose of this utility model is achieved through the following technical solutions:
A kind of automotive tyre nut pre-tightening apparatus, described device includes fixed plate, bearing, back-up ring, handle, master gear, little
Gear, sleeve, spring washer, nut；Fixed plate centre is machined with shoulder hole, and handle is through being arranged in central stepped
Bearing and back-up ring are connected with fixed plate, and master gear is connected by nut and spring washer are fixing with handle, the circumference in fixed plate
Being uniform-distribution with trapezoidal hole, little gear bearing in being arranged on trapezoidal hole and back-up ring are connected with fixed plate, and sleeve weld is little
On gear, driving gear and the engagement of little gear.
Advantage of the present utility model with effect is:
This utility model realizes on tire pretension while multiple nuts, and need not carry out pretension one by one, improves peace
Dress work efficiency.Driving gear and little gear are in engagement, and handle rotates and drives master gear to rotate, and is delivered to little tooth
Wheel, sleeve rotates simultaneously, thus can the simultaneously multiple lug nut of pretension, thus realize tyre pretightening.And need not one one
Individual come pretension, improve the work efficiency of pretension lug nut.Due to different tires, the number of nut is different, as required
Selecting the number of little gear, the use making tyre pretightening mechanism is more flexible.
Accompanying drawing explanation
Fig. 1 is tyre pretightening mechanism of the present utility model front view；
Fig. 2 is tyre pretightening mechanism of the present utility model left view.
Detailed description of the invention
This utility model is described in detail by illustrated embodiment below in conjunction with the accompanying drawings.
As it can be seen, parts in figure: 1 fixed plate, 2 bearings, 3 back-up rings, 4 handles, 5 master gears, 6 back-up rings, 7 bearings, 8 little teeth
Wheel, 9 sleeves, 10 spring washers, 11 nuts.Handle 4 is connected with fixed plate by bearing 2, with master gear 5 by nut 11 and bullet
Spring packing ring 10 connects fixing, and little gear 8 is connected with fixed plate by bearing 7 and back-up ring 6, and sleeve 9 is arranged on little gear 8, hands
Handle rotation driving pinion and sleeve rotate simultaneously, thus realize tyre pretightening.It is empty that fixed plate center and periphery are machined with ladder,
Bearing can be installed, and fixed with fixed plate by baffle plate 3, baffle plate 6 and be connected.Little gear 8 totally 5, and it is evenly distributed on fixed plate
On circumference.Master gear drives little gear to rotate.Master gear 5 is fixed on handle 4 by nut 11 and spring washer 10.Sleeve 9
It is welded on little gear.Fixed plate 1 is a circular slab, and centre is machined with shoulder hole.Handle 4 is as it can be seen, generally
Revolving structure, it is machined with cannelure, it is simple to hold during work, and it is by the bearing 2 being arranged in central stepped and gear
Circle 3, it is achieved be connected with the axial restraint of fixed plate 1.Master gear 5 and little gear 8 as it is shown in figure 1, process the gear teeth on circular slab,
Center is machined with circular hole.Master gear is connected by nut 11 and spring washer 10 are fixing with handle so that rotary handle 4 can be real
The rotation of existing master gear 5.On circumference in fixed plate, be also uniform-distribution with 5 trapezoidal holes, little gear 8 by be arranged in
Bearing 7 and back-up ring 6 in the trapezoidal hole of circle distribution are connected with fixed plate, and sleeve weld is arranged on little gear 8, in sleeve
Portion is machined with polygonized structure, it is simple to nut screw connection.Driving gear 5 and little gear 8 are in engagement, 4 turns of handle all the time
Dynamic driving master gear 5 to rotate, and be delivered to little gear 8, sleeve 9 rotates simultaneously, thus can pretension multiple tire spiral shell simultaneously
Mother, thus realize tyre pretightening.Depending on the number of little gear is according to the number of lug nut, and pretension need not be carried out one by one,
Improve the work efficiency of pretension lug nut.The use making tyre pretightening mechanism is more flexible, easy and simple to handle.
