Description
Technical field
The utility model relates to military ball firing training equipment field, says it is a kind of transmission device of back starting target in detail.
Background technology
As everyone knows: in military ball firing training, how to guarantee the operate as normal of target bar, transmission mechanism has been proposed very high stability requirement, there are problems in existing drive technology, as poor stability, current transmission mechanism can not assurance mechanism operate as normal, cause stuck phenomenon easily, influenced normally carrying out of training; Cycle lie is short, because of present this mechanism can not guarantee rational lubricating system, causes the projected life that can not reach expection service life of equipment, and Xun Lian expense cost is always than the height of expecting thus; Mechanism's complexity, bulky, cost an arm and a leg, these factors cause maintenance at ordinary times, repair complicatedly, the layman can not finish, and bulky having brought carried inconvenience etc. when training, these factors are seriously restricting training at ordinary times, thereby cause, and training can not be carried out normally.
Summary of the invention
The purpose of this utility model just is to overcome the deficiencies in the prior art, and a kind of transmission device of back starting target is provided, and this transmission structures is simple, and transmission is stable, and volume is little, cost is lower, has adjustability.
The utility model adopts following technical solution: a kind of transmission device of back starting target, be provided with pedestal, be fixed with motor on the pedestal, one end of the output shaft of motor and crank is fixed, and the other end of crank is hinged together through crank axle and connecting rod one end, and the other end of connecting rod is connected with rocking bar one end through jointed shaft, the middle part of rocking bar is fixed on the pedestal through rotating shaft, the other end of rocking bar and slide bar one end are hinged, and the other end and the main shaft of slide bar are fixed together, and main shaft is fixedlyed connected with the target bar.
The utility model also can be realized by following measure: the connecting rod two ends are to be connected with crank, rocking bar by universal bearing.The connecting rod two ends are equipped with the silk axle.
The beneficial effects of the utility model are, and are simple in structure, and transmission is stable, are easy to carry about with one, cost is lower, has adjustability.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, to help understanding content of the present utility model.
As shown in Figure 1 and Figure 2, the utility model is made up of motor 1, crank axle 2, crank 3, connecting rod 4, jointed shaft 5, rocking bar 6, slide bar 7, main shaft 8, bearing 9, pedestal 10, hexagonal strut 11.Be fixed with motor 1 on the pedestal 10, one end of the output shaft of motor 1 and crank 3 is fixed, the other end of crank 3 is hinged together through crank axle 2 and connecting rod 4 one ends, the other end of connecting rod 4 is connected with rocking bar 6 one ends through jointed shaft 5, and the middle part of rocking bar 6 is fixed on the pedestal 10 through rotating shaft, and the other end of rocking bar 6 and slide bar 7 one ends are hinged, the other end of slide bar 7 and main shaft 8 are fixed together, main shaft 8 is fixedlyed connected with the target bar, and main shaft 8 is embedded with copper sheathing, and has assembled lubricating arrangement.Connecting rod 4, rocking bar 6 provide power by motor 1, transfer torque to crank 3, and crank 3 transfers torque to connecting rod 4 again by coupled crank axle 2, successively transmission of power are arrived rocking bar 6, slide bar 7 and main shaft 8 by jointed shaft 5; Pedestal 10 and hexagonal strut 11 mainly are the effects of playing fixed conveyor mechanism.Crank 3 formation that is connected through the hinge allows certain offset in the process of connection, slide bar 7 is realized transmitting by copper sheathing with the transmission of main shaft 8 power, mainly is to consider wearability, cycle period life-span, reliability etc.
In order to make rocking bar 6 accurate in locating in the course of the work, minimizing is connected the friction between the part with each, and can realize movement locus accurately and in the process that complete machine mechanism is installed, realize adjustability, step up so take to position by two axis in the both sides of rocking bar 6, also to reserve certain free gap simultaneously, in order to avoid mechanism's heating in the process of work causes expanding with heat and contract with cold between the connector, influence the operate as normal of transmission mechanism.
The joint circular hole inside of connecting rod 4 is being connected by universal bearing and crank 3, rocking bar 6, the outstanding advantage of this kind connected mode is to allow transmission mechanism in the process of motion certain offset can be arranged, when in a small amount deflection, stuck phenomenon can not appear, avoided motor excessive, thereby the situation that causes burning motor 1 take place because of the immediate current that stall causes.What connect connecting rod 4 two ends is the silk axle, the effect of silk axle is the adjustability that realizes connecting rod 4, solved each drive disk assembly in the process of processing, the driving error that causes because of the production error, under the length of connecting rod 4 can guarantee situation that transmission requires, realize locked to connecting rod 4 by dig-inning nut, guaranteed the accuracy of connecting rod 4 length, guarantee that also the target bar rotates in 0～90 ° scope.
Being connected by copper sheathing between slide bar 7 and the main shaft 8 realizes as the intermediate conversion part, be connected sliding friction between slide bar 7 in this transmission mechanism and the copper sheathing, inevitably will produce a large amount of heats thus, for this has been designed to the stepped of lubricating cup effect to copper sheathing inside, internal storage lubricating grease, and the hydraulic fluid port of lubricating grease is added in reservation, can carry out regular interpolation lubricating grease to it, avoided the dry friction between metal and the metal, for setting up one deck oil film between slide bar 7 and the copper sheathing, make between the two friction based on boundary friction.
