Description

Technical Field

[0001] The utility model belongs to the technical field of lifting equipment, and in particular relates to a universal combined gear ring conversion accessory for a single- and double-cone lock ring synchronizer. Background Art

[0002] At present, the common lock ring synchronizers are single cone synchronizers and double cone synchronizers. According to their performance requirements, lock ring synchronizers can develop structures with different numbers of cone surfaces. Common ones are single cone synchronizers and double cone synchronizers. For single cone synchronizers, the cone surface of the gear ring is combined with the cone surface of the outer ring to form a single friction pair; for double cone synchronizers, the gear ring does not have a cone surface, and the inner, middle and outer cone rings of the synchronizer cooperate to form a double friction pair.

[0003] At present, for the development of single and double cone synchronizers, different combined gear rings are designed at home and abroad to adapt to different structures, which results in that the combined gear rings of single and double cone synchronizers with the same external dimensions cannot be used universally.

[0007] Furthermore, the outer wall surface of the locking ring is annular.

[0008] Furthermore, the outer wall surface of the locking ring is conical.

[0009] Furthermore, the connecting piece and the locking ring are an integrated structure.

[0010] Furthermore, there are six connecting pieces, and each of the connecting pieces is evenly distributed at the end of the locking ring.
