Description

Six-head floor grinder gearbox

technical field

The utility model relates to the field of grinders, in particular to a six-head floor grinder gear box used for grinding and polishing stone and concrete floors.

Background technique

The floor grinder is mainly used for grinding and polishing of large and medium-scale ground. It can effectively grind stone, concrete surface, epoxy mortar layer and old epoxy floor, etc. The existing grinding machine gear box adopts a fixed-axis gear train transmission with double-head and four-head work output, the working area is small, the force in each direction is uneven during grinding, it is easy to shake, and the stability is poor. With the rapid development of society, high efficiency and low cost have become the mainstream demands.

Utility model content

The purpose of the utility model is to overcome the above disadvantages and provide a six-head floor grinder gearbox with high grinding efficiency and good grinding effect.

In order to achieve the above purpose, the technical solution of the utility model is: a six-head floor grinder gearbox, including a box body and an upper box cover arranged above the box body, and an input gear for inputting power is provided in the middle of the box body , the input gear is meshed with three sets of gear assemblies, and the three sets of gear assemblies are uniformly distributed in the outer circumference of the input gear; each set of the gear assemblies includes a first gear, a second gear, a positive output gear, a reverse output gear and a steering gear. gear, the first gear meshes with the input gear, the first gear is coaxial with the second gear and can drive the second gear to rotate, the positive output gear and the steering gear both mesh with the second gear, and the reverse output gear meshes with the steering gear , both the positive output gear and the reverse output gear output power to the grinding head through their output shafts.

Preferably, a middle box cover is provided between the upper box cover and the box body, a gear plate is fixed in the middle of the middle box cover, and the gear plate is engaged with a planetary gear, and the planetary gear is sleeved on the positive output gear On the output shaft of the planetary gear, the planetary gear can drive the gearbox to rotate by meshing with the fixed gear plate.

By adopting the above-mentioned technical scheme, the beneficial effects of the utility model are: the utility model can realize a single power input to drive six grinding heads, the working area is large, and the grinding efficiency is higher than that of a single or double grinding head floor grinder; The multi-stage gear transmission output effectively buffers the meshing force between the gears, reduces the vibration and ensures the grinding quality; the ring gear assembly is evenly distributed on the outer circumference of the input gear, so that the entire working disc rotates to balance the force, reduce the vibration of the machine, and improve the grinding quality. Work comfort; the grinding disc on the adjacent output shaft turns in the opposite direction, and the entire gearbox is driven by the planetary gear to realize rotation, both of which can well offset the traction force of the floor grinder.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1 and 2, the six-head floor grinder gear box of the present utility model includes a box body 5 and an upper box cover 1 located above the box body 5, and the middle part of the box body 5 is provided with an input gear 6. The input shaft of the input gear 6 can be connected to the motor for input power. The input gear 6 is meshed with three sets of gear assemblies 7, and the three sets of gear assemblies 7 are evenly distributed on the outer circumference of the input gear 6; each set of the gear assemblies 7 All comprise first gear 71, second gear 72, positive output gear 74, reverse output gear 75 and steering gear 73, described first gear 71 engages input gear 6, first gear 71 and second gear 72 coaxial and can To drive it to rotate, the positive output gear 74 and the steering gear 73 are all meshed with the second gear 72, and the reverse output gear 75 is meshed with the steering gear 72, so that the steering of the positive output gear 74 and the reverse output gear 75 are opposite, and they can cancel each other out. The traction force at the time, the positive output gear 74 and the reverse output gear 75 all output power through the output shaft grinding head; the middle case cover 3 is arranged between the upper case cover 1 and the case body 5, and the middle case cover The middle part of 3 is fixed with a gear plate 2, and the gear plate 2 is meshed with a planetary gear 4, and the planetary gear 4 is sleeved on the output shaft of the positive output gear 74, and the planetary gear 4 can be meshed with the fixed gear plate 2 Drive the gear box of the utility model to rotate around the middle part.

The above is only a preferred embodiment of the utility model, and cannot limit the scope of the utility model implementation. All equal changes and decorations made according to the patent scope of the utility model should still belong to the scope covered by the utility model Inside.
