Below in conjunction with the drawings and specific embodiments detailed content of the present utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model cyclic train planetary gear reducing mechanism.
The specific embodiment
As shown in Figure 1: a kind of electric automobile board spring bolt special puller, it comprises motor 1, vehicle frame 2, electric apparatus control apparatus 3, small teeth number difference planet gear reducing gear 4, fixed shaft gear train bevel gear reducer structure 5, cyclic train planetary gear reducing mechanism 6 and cabinet 7;
The gearratio of cyclic train planetary gear reducing mechanism 6 is 3-5 doubly (i=3-5), it is installed in the output of fixed shaft gear train bevel gear reducer structure 5, it forms (as shown in Figure 2) by power output shaft (3X frame axle) 61, Sunny gear 62, planet pin 63, large sun gear (3N internal gear) 64 and planetary gear 65, the top of Sunny gear 62 connects with large sun gear 64 by planetary gear 65, planet pin 63, and planet pin 63 connects with power output shaft 61; The bottom of Sunny gear 62 is fixedly connected by the bevel gear wheel 51 of involute spline and fixed shaft gear train bevel gear reducer structure 5, make power input cyclic train planetary gear reducing mechanism, make the power of input obtain amplifying by deceleration, again by power output shaft 61 outputs, thereby greatly reduce the load of bevel gear, be greatly enhanced the service life of bevel gear, like this since, the reliability of entire equipment is greatly improved;
Cabinet 7 is an all-sealed structure, it comprises as lower member: loam cake 71, lower cover 72, casing 73, oil sealing 74 and flange coil pipe 75, be large sun gear 64 between loam cake 71 and the lower cover 72, obturator is all arranged between member, all adopt between member and be fixedly connected, form a hermetic cabinet, fill with lubricating oil in the hermetic cabinet, thereby make that planetary gear in the cabinet is paid, bevel gear pair, bearing and other kinematic pair obtained well lubricated, improve transmission efficiency, reduced the wearing and tearing of gear pair, improved the service life of gear of device interior.
Electric apparatus control apparatus 3 is main components and parts by motor protecter, and equipment is protected when bad conditions such as overload, phase shortage, short circuit occurring.
Owing to the input that fixed shaft gear train is placed on planetary gear reducing mechanism,,, also can adopt fine module gear to satisfy strength demand even bevel gear is the monodentate carrying because load is little.
In order to utilize minimum material, reach maximum output torque, we choose the spur gear that modulus is m=2-2.5 in planet circular system, in fixed shaft gear train, choose the bevel gear that modulus is m=4-6, and the internal structure of reducing gear carried out good layout, owing to taked close-toothed gear, compact appearance structure, and the moment of torsion of output is very big, and it is very big to pretend the planetary gear and the load on the mandrel that are used for planet circular system; For reducing the load of this planetary gear and wheel shaft, taked to arrange the structure of three planetary gears, the load of its single gear teeth and mandrel is descended greatly.
Owing to adopted Bevel Gear Transmission, change the transmission direction of moment of torsion, thereby reduced height, make operating space of the present utility model reach the demand of real service clearance.
By above-mentioned layout, solved the contradiction of contradiction, operating space and the service clearance of load and structure well, Sunny gear 62, planetary gear 65 load, planet pin 63 and bevel gear wheel 51 in the planet circular system, the load of bevel pinion 52 are descended greatly, safety coefficient reaches unanimity, and has improved reliability of products and service life greatly.
When the user uses, only need on the square head of utility model power output shaft 61, to put the sleeve of 1 o'clock internal square hole, hand-held then vehicle frame handle of the present utility model, with the utility model jacket casing on the nut of spring bolt, the two-direction switch that rotates in the electric apparatus control apparatus according to the direction of dismounting needs powers up to motor then, can reach the work purpose of tearing pine open or tightening spring bolt.
Operation principle of the present utility model is: with the electric current input motor, motor changes into mechanical energy with electric energy and exports to the small teeth number difference planet gear reducing gear power supply by electric apparatus control apparatus; The small teeth number difference planet gear reducing gear is exported to fixed shaft gear train bevel gear reducer structure by slowing down with the mechanical energy amplification of motor input; Fixed shaft gear train bevel gear reducer structure is exported to the cyclic train planetary gear reducing mechanism by slowing down with the mechanical energy amplification of small teeth number difference planet gear reducing gear input; The cyclic train planetary gear reducing mechanism amplifies 1 o'clock sleeve exporting to the connection of power output shaft 61 front end square heads by slowing down with the mechanical energy of fixed shaft gear train bevel gear reducer structure input, to drive the nut rotation work done of U bolt.
