Description

Wear-resistant duplex driven gear

Technical Field

The utility model relates to the technical field of gears, especially, relate to a stand wear and tear pair driven gear.

Background

The duplicate gear is a very critical part in a speed-changing clutch system, and the comprehensive performance of the duplicate gear plays a key role in the whole transmission structure. In particular to the field of high-speed transmission, strict requirements are put on the dynamic balance performance of the gear. Therefore, in the prior art, dynamic balance adjustment is generally required by adding lightening holes before the initial operation of the gear. Although the dynamic balance performance of the gear in the early operation can be effectively ensured in the mode, the gear is abraded more or less in the using process, and the gear is gradually unbalanced. Once the dynamic balance of the gear is deteriorated, the overall vibration and abrasion are further aggravated, and even early failure and low service life are caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome above-mentioned problem, and provide a can finely tune guarantee balanced stand wear and tear pair driven gear, prolong holistic life.

The technical scheme of the utility model is that: a stand wear and tear pair driven gear, including the gear shaft of taking the centre bore and two gear rings that are located the gear shaft both ends, its characterized in that: an annular groove concentric with the central hole is concavely arranged on the axial outer end face of the gear ring, a plurality of balance seats are embedded in the annular groove, and the balance seats are connected in a sliding manner along the annular groove; the balance seat is provided with a positioning screw hole which axially penetrates to the bottom of the annular groove, and the balance seat further comprises a plurality of positioning screws, and the positioning screws are screwed in the positioning screw holes in a one-to-one corresponding mode and tightly abut against the bottom of the annular groove; every it is provided with a balancing piece to slide on the balancing seat, the slip direction of balancing piece is the same rather than the radial of place gear circle, one side that the balancing seat leaned on the gear circle center is equipped with an arch, threaded connection has a fine setting screw that extends along balancing piece slip direction on the arch, fine setting screw wears to establish in the balancing seat and one end rotationally fixes on the balancing piece.

Borrow by above-mentioned structure, the utility model discloses can be when the gear is unbalanced, adjust the circumferential position of balanced seat in the ring channel in a flexible way and finely tune the radial position of balancing piece on balanced seat to make two gear rings can remain balanced state all the time, avoid the circumstances such as unbalance aggravation wearing and tearing.

Further, stand wear and tear pair driven gear in, gear ring, gear shaft integrated forging shaping, the processing of being convenient for.

Further, among the stand wear and tear pair driven gear, a plurality of lightening holes have still been seted up to the gear circle, alleviate holistic weight.

Further, among the stand wear and tear pair driven gear, the location screw is located and keeps away from the bellied other end on the balanced seat.

The utility model has the advantages that:

the utility model discloses simple structure, reasonable in design can be through the adjustment mode that the balancing piece distribution position that adjusts the distribution position of balanced seat in the ring channel and on each balanced seat combined together, can effectively couple the holistic balance performance of gear, solves the gear unbalance condition, demonstrates better dynamic balance performance, is showing the condition of having alleviated unbalance wearing and tearing, and is more stand wear and tear, and life is better.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings:

referring to fig. 1 and 3, the wear-resistant dual driven gear according to the present embodiment includes a gear shaft having a central hole and two gear rings 1 at both ends of the gear shaft. The gear ring 1 and the gear shaft are integrally forged and formed, and the gear ring 1 is provided with a plurality of lightening holes 8. The outer terminal surface of the axial of gear circle 1 is gone up the concave ring channel 2 that is equipped with the centre bore is concentric, ring channel 2 is embedded to be equipped with a plurality of balanced seats 3, balanced seat 3 slides along ring channel 2 and connects. With reference to fig. 2 and 3, the balance seat 3 is provided with a positioning screw hole axially penetrating to the bottom of the annular groove 2, and further comprises a plurality of positioning screws 4, and the positioning screws 4 are screwed in the positioning screw holes in a one-to-one correspondence manner and abut against the bottom of the annular groove 2. Every it is provided with a balancing piece 5 to slide on the balance seat 3, the slip direction of balancing piece 5 is the same rather than the radial of place gear circle 1, one side that the balance seat 3 leaned on the gear circle 1 center is equipped with a arch 6, it should explain that, the location screw is located the other end of keeping away from arch 6 on the balance seat 3. The bulge 6 is connected with a fine adjustment screw 7 extending along the sliding direction of the balance block 5 in a threaded manner, the fine adjustment screw 7 penetrates through the balance seat 3, and one end of the fine adjustment screw is rotatably fixed on the balance block 5.

When the gear is unbalanced, the positioning screw 4 is firstly unscrewed, the balance seat 3 slides to a proper position in the annular groove 2, and then the positioning screw 4 is screwed again to be fixed at the current position; secondly can also make the length that fine setting screw 7 radially stretched into in the balanced seat 3 change through rotatory fine setting screw 7, promote balancing piece 5 and realize radial slip on balanced seat 3 to change its weight distribution, above-mentioned both adjustment methods combine together, can realize the balance adjustment of pair driven gear betterly, improve its balanced wear resistance, prolong its life.

The specific embodiments described herein are merely illustrative of the principles of the present invention and its efficacy, and are not intended to limit the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Therefore, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical idea of the present invention shall be covered by the claims of the present invention.
