Abstract

A one-way bearing is provided with a clutch inner core between an out casing and an inner ring, and the inner core is provided with a cyclic top head and a cyclic lower cover, between which a plurality of wedge rollers are adjacently arranged. The lateral side of the wedge roller facing the clutch inner core is irregular arc surface, while the inside thereof facing the clutch inner core is regular, and the adjoining regular arc surfaces are provided in a square waveform cage in the inside of the clutch inner core to locate at intervals. The lateral surface of the wedge roller is provided with at least one spring groove, and the astriction springs are embedded in the spring grooves which are in the wedge rollers arranging in circular permutation. The machinery such as the textile machine and the printing machine applying the utility model can effectively improve the utilization efficiency of the one-way bearing.

Description

A kind of unilateral bearing

Technical field

The utility model belongs to mechanical transmission, particularly relates to a kind of a kind of unilateral bearing that is used for frame, printing machinery.

Background technique

The existing unilateral bearing (also claiming overrunning clutch) that is used for frame, printing machinery all is to adopt ratchet clutch, and promptly its inner core is to adopt roller to embed between the ratchet of the ratchet cover plate, and its unidirectional transmission relies on ratchet, rotates by roller again.Its shortcoming is that ratchet is difficult to accomplish accurate five equilibrium, and makes unbalance stress, and roller is easy to slippage, the utilization efficiency of influence machinery.

Summary of the invention

The purpose of this utility model is a kind of a kind of unilateral bearing that can address the aforementioned drawbacks of design.

The technological scheme that realizes above-mentioned purpose is as follows:

A kind of unilateral bearing, have overcoat and inner ring, be provided with the clutch inner core between overcoat and inner ring, the clutch inner core has the loam cake and the lower cover of ring-type, adjacently between loam cake and lower cover be arranged with some voussoir rollers, the voussoir roller is irregular cambered surface towards the clutch inner core outside, it is regular cambered surface towards clutch inner core inboard, and adjacent regular cambered surface is set at the square waveform retainer positioned at intervals of clutch inner core inboard, outer side surface at the voussoir roller also has at least one spring groove, tightens up in the spring groove that spring embeds all voussoir rollers of arranging in the form of a ring.

The inside edge of aforesaid upper and lower cover has and stretches out and spaced gulde edge, supports the crest of described retainer, the cross bar at trough place.

The utility model has the advantages that: machinery such as frame, printing press adopts the utility model, can effectively improve utilization efficiency.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the A-A cross-sectional schematic of Fig. 1.

Among the figure, 1 is overcoat, and 2 is inner ring, and 3 is the clutch inner core, and 4 is the voussoir roller, and 5 is loam cake, and 6 is lower cover, and 7 is retainer, and 8 is gulde edge, and 9 for tightening up spring, and 41 is spring groove, and 71 is cross bar.

Embodiment

Below in conjunction with description of drawings the utility model embodiment:

2 of overcoat 1 and inner rings are provided with clutch inner core 3, clutch inner core 3 has the loam cake 5 and lower cover 6 of ring-type, 6 of loam cake 5 and lower covers be adjacent to be arranged with some voussoir rollers 4, voussoir roller 4 is irregular cambered surface towards clutch inner core 3 outsides, it is regular cambered surface towards clutch inner core 3 inboards, and adjacent regular cambered surface is set at square waveform retainer 7 positioned at intervals of clutch inner core 3 inboards, outer side surface at voussoir roller 4 also has twice spring groove 41, tightens up spring 8 and embeds in the spring groove 41 of all voussoir rollers of arranging in the form of a ring.

The inside edge of upper and lower cover has and stretches out and spaced gulde edge 8, the crest of supporting square waveform retainer 7, the cross bar 71 at trough place.

Claims

1, a kind of unilateral bearing, have overcoat and inner ring, be provided with the clutch inner core between overcoat and inner ring, the clutch inner core has the loam cake and the lower cover of ring-type, it is characterized in that: adjacently between loam cake and lower cover be arranged with some voussoir rollers, the voussoir roller is irregular cambered surface towards the clutch inner core outside, it is regular cambered surface towards clutch inner core inboard, and adjacent regular cambered surface is set at the square waveform retainer positioned at intervals of clutch inner core inboard, outer side surface at the voussoir roller also has at least one spring groove, tightens up in the spring groove that spring embeds all voussoir rollers of arranging in the form of a ring.

2, a kind of unilateral bearing according to claim 1 is characterized in that: the inside edge of described upper and lower cover has and stretches out and spaced gulde edge, supports the crest of described retainer, the cross bar at trough place.
