The technical scheme of the utility model as follows:

the utility model provides a heavily block with safe durable gear, includes that the center pin is conical gear major structure for upper and lower direction main part, gear major structure's lower extreme central point puts and is equipped with the central assembly combination hole that runs through whole up end, be equipped with circumference evenly distributed and the ascending block of slope on gear major structure's the conical surface in the outside and connect the tooth, gear major structure's upper end is equipped with keeps away a cooperation mounting groove, its characterized in that: keep away the border position of the outer cylindrical structure of lower extreme of position cooperation mounting groove and be equipped with the heat dissipation safety lubrication groove that the cross-section that the center pin is the same is inverted isosceles trapezoid, keep away the outside position of position cooperation mounting groove and be equipped with the opening upwards and with every the crossing inverted cone shape main part cooperation lubrication groove of block connection tooth.

Furthermore, the diameter of the lower end position of the main body matching lubricating groove is the same as the diameter length of the lower end face of the avoiding matching mounting groove.

Furthermore, the depth of the avoiding matching mounting groove in the vertical direction is smaller than half of the thickness of the gear main body structure in the vertical direction.

Furthermore, the taper angle of the heat dissipation safety lubrication groove is the same as the taper angle of the main body matching lubrication groove.

The utility model has the advantages that:

the utility model discloses a brand-new structural design sets up two sets of cooperation lubrication grooves through the main part mounted position at gear structure, not only can carry out corresponding heat dissipation to the heat that the major structure produced when using to can carry out corresponding lubrication to every block tooth, it is better to have ensured the whole durability in the use, the safety in utilization is more reliable, can effectively improve the life-span of gear when using, the stability of guarantee heavily blocking transmission assembly when using is better.

Detailed Description

As shown in fig. 1 to 7, a heavily block with safe durable gear, it adopts brand-new structural design, main part mounted position through at gear structure sets up two sets of cooperation lubrication grooves, not only can carry out corresponding heat dissipation to the heat that the main part structure produced when using, and can carry out corresponding lubrication to every block tooth, it is better to have ensured whole durability in the use, the safety in utilization is more reliable, can effectively improve the life-span of gear when using, the stability of guarantee heavily block transmission assembly when using is better. The gear comprises a gear main body structure 1 with a conical main body in the vertical direction and a central assembly combination hole 2 penetrating through the upper end face of the whole body, wherein the central shaft is a central shaft, and the whole body is assembled and fastened through the central assembly combination hole 2. The conical surface of the outer side of the gear main body structure 1 is provided with clamping connecting teeth 3 which are uniformly distributed on the circumference and incline upwards, and the clamping connecting teeth are main body clamping teeth when in use. The upper end of the gear main body structure 1 is provided with a avoiding position matching installation groove 4 which plays a role in avoiding positions during installation. Keep away the border position of the outer cylindrical structure of lower extreme of position cooperation mounting groove 4 and be equipped with the heat dissipation safety lubrication groove 5 that the same cross-section of center pin is inverted isosceles trapezoid, and this position cooperation lubrication liquid can carry out corresponding lubrication to the heat that produces in the major structure in the use. And an inverted cone-shaped main body matching lubricating groove 6 with an upward opening and intersected with each clamping connecting tooth 3 is arranged at the outer side position of the avoiding position matching mounting groove 4. The cooperation lubricating liquid can carry out even lubricating liquid to every block tooth position and carry, and the guarantee is better at the whole lubricated effect in the use, and the safety and stability nature in the use more can obtain the guarantee.

Preferably, the diameter of the lower end of the main body matching lubricating groove 6 is the same as the diameter of the lower end face of the avoiding matching mounting groove 4 in length, so that the production is more convenient, and the matching smoothness of lubricating liquid is better in use.

Preferably, the depth of the avoiding fitting installation groove 4 in the vertical direction is smaller than half of the thickness of the gear main body structure 1 in the vertical direction, so that the strength of the whole structure can be better ensured, and the safety in use can be further improved.

Preferably, the taper angle of the heat dissipation safety lubrication groove 5 is the same as the taper angle of the main body matching lubrication groove 6, so that the convenience in production is higher, and the cost in production can be effectively reduced.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications or replacements can be made without departing from the principle of the present invention, and these modifications or replacements should also be considered as the protection scope of the present invention.
