Gear-box planetary gear shaping die

Abstract: The invention relates to a forming die of a gearbox planet gear, belongs to the processing dies of car automatic gearbox planet gears, solves the problems in prior forging die, including big forging force, rigorous requirement for blanks, and short service life of the die, and satisfies the forming requirement of a car automatic gearbox planet gear. The forming die comprises an upper die and a lower die arranged symmetrically and vertically; the end faces of both an upper punch and a lower punch are bosses; a diffluent trough is formed on the boss of the lower punch; the shoulders of both the upper punch and the lower punch extend into a tooth-shaped cavity die by 1-2mm in the final extrusion state; a rotary ejection mechanism can also be arranged; the lower punch can rotate when being ejected; and a helical cylindrical gear with a bigger helix angle can be forged. The forming die has the advantages of simple structure, easy manufacture and installation, small forming force and low requirement for blanking precision. Furthermore, the forming die can realize single punch extrusion according to different die carriers and equipment, double punch extrusion in opposite directions, as well as the extrusion of the helical cylindrical gear with big helix angle.

Inclination angle adjusting device for working platform of gear shaping machine

Abstract: A device adjusting the inclination of the worktable of a gear slotting machine belongs to the parts of the gear slotting machine The main structure of the device comprises a main worktable shaft and a base, arc-shaped guideways are arranged between the base and a rotary tank, a worm is mounted on the base, a worm wheel is firmly combined with the rotary tank, and the worm is cooperated with the worm wheel With the cooperation between the arc-shaped guideways and the worm and the worm wheel, the device can ensure that a reversed taper angle can be kept stable and the stability and precision of gear slotting is high and also that the deflective swing amplitude of the surface of the worktable is reduced and the diameter of the surface of the worktable is enlarged, thus expanding the range of processing the outer diameter of a workpiece, meanwhile, angle adjustment is also convenient, not only are the processing specifications of an ordinary gear slotting machine maintained, but also processing on positive-angled and negative-angled inverse taper gear is realized, and the problem of processing an inverse taper gear with a large diameter is resolved

Driving type semi-trailer

Abstract: The utility model relates to a driving type semi trailer, which can effectively solve the problem that the semi trailer can run normally under the situation of poor pavement. The utility model adopts the structure that a power take off device and a gear pump are installed on the gear box of the tractor, a controller and a hydraulic oil tank are installed at the rear part of the tractor, a driving device is arranged at the lower part of the semi trailer body, the driving device is formed by connecting a single-input axle driving axle and two double-input axle driving axle with an electro-hydraulic gear shaping type clutch through two rear driving axles and a front driving axle, an electro-hydraulic gear shaping type clutch is combined into a whole body with a hydraulic motor through the hydraulic torque converter in the middle, and controlled by an electro-hydraulic change valve connected with a hydraulic motor, the electro-hydraulic change valve is connected with a heat radiator through an oil pipe, the heat radiator is connected with the hydraulic oil tank through an oil pipe, the electro-hydraulic gear shaping type clutch and the electro-hydraulic change valve are connected with the electric controller, to realize the control, the structure of the semi trailer is novel and unique, the adaptability is strong, the semi trailer can normally run on the poor pavement, the oil is saved and the energy is also saved, and the economic efficiency and the social efficiency are predominant.

Side-wise adjusting device of gear shaping machine

Abstract: The utility model relates to a lateral adjusting device of gear shaper, belonging to components of gear shaper, which mainly comprises a tool holder body and an upright column. The tool holder body is supported on a stand by flanges and the shafts matched with the upright column and the tool holder body are eccentric shafts. The utility model adopts the shaft matched with the upright column and the shaft matched with the tool holder body to be eccentric shafts. The height of the support hole of the tool holder body and the heights of the left and the right of the tool holder body can be adjusted when rotating the flanges. The height of the support point of the tool holder body can be adjusted by rotating the flanges when the lateral precision of the gear shaper is running out, so the angle of the movement of the main shaft can be adjusted. The gear shaper adopted the utility model dose not need to disassemble the parts of the tool holder body when adjusting the lateral precision and add the joint surface of upright column, so the utility model has the advantages of simple adjustment and convenient operation.

Miniature planetary gear speed reducer

Abstract: A micro satellite gear reducer includes a shell (1) and an internal gear (3) fixed in the shell (1), wherein, the internal gear (3) is formed by overlapping and assembling a plurality of punched internal gear plates (5). Compared with the internal gear of the existing micro satellite gear reducer, the manufacturing cost of the internal gear of the micro satellite gear reducer is far lower than that of a gear shaping or a broaching gear using a moulded broaching tool, and the quality of the product is also more stable and reliable. The utility model aims to provide the micro satellite gear reducer with stable and reliable product quality, and low manufacturing cost.

Vibration-suppressing mechanism for gear-shaping machine

Abstract: This aims to provide a vibration-suppressing mechanism for a gear-shaping machine, which is enabled to suppress mechanical vibrations at the time of shaping a helical gear by selecting an optimum balance weight. The vibration-suppressing machine is provided for the gear-shaping machine which performs the gear shaping on a work (W) with a cutter (T) mounted on a main spindle (26) of crank reciprocations. The vibration-suppressing machine comprises balance shafts (16 and 17) juxtaposed with respect to a crankshaft (15), for rotating at an identical rotation speed in synchronism with the crankshaft (15) and in the same and opposite directions as and to that of the crankshaft (15), main balance weights (41 and 42) removably mounted on the crankshaft (15), for suppressing the axial vibrations of the main spindle (26), and auxiliary balance weights (43 to 46) removably mounted on the balance shafts (16 and 17), for suppressing the vibrations of in directions perpendicular to the axial direction of the main spindle (26). Those individual balance weights (41 to 46) are selected on the basis of leads meeting the stroke width of the main spindle (26) and the torsional angle of the work (W).

Main drive unit for gear shaping machine

Abstract: A main drive unit of a gear shaper belongs to the gear shaper parts. The main structure comprises a transmission chain mechanism, which is connected with a sliding block through a crank connecting rod. The sliding block is positioned on a linear rolling guide rail, on which a pin roller is arranged. The friction resistance between the sliding block and the guide rail is reduced, the work noise and power loss are decreased and the operational reliability of the equipment is promoted by the pin roller through the structure that the sliding block is positioned on the linear rolling guide rail.
