Abstract
The utility model discloses a seal end cover for a transmission shaft of transmission machinery. The seal end cover is formed by combining an end cover, a screw plug, a locating ring, an elastic collar for a hole, a rotary-shaft lip seal ring and a shoulder. The bottom of the rotary-shaft lip seal ring is provided with one shoulder integrated with the end cover, and a gap between the outer diameter dimension of the shoulder and a sealed shaft is 0.4-0.5mm. A threaded hole is formed in a circumferential position of the end cover, and the screw plug is installed in the threaded hole. The locating ring is arranged in the rotary-shaft lip seal ring, and a ring oil groove is formed in the locating ring. The elastic collar for the hole is installed in the end cover. The sealing performance of the end cover is increased, and the using efficiency of the end cover is improved. The seal end cover has the advantages of simple structure, easiness in process, convenience in field maintenance and low cost.
Description
Technical field
The utility model relates to a kind of transmission shaft of gearing and uses end cover.
Background technique
At present, it is mechanical seal that the end cap of driving mechanism transmission shaft adopted more, the mechanical seal good sealing effect; But compare with other sealing and to cost an arm and a leg; Some manufacturing procedure precision prescribed of end cap is high, needs certain technical merit when assembled, adjustment, and installation process is somewhat complicated, effort also; After the product export operation, when keeping in repair at the scene,, cause maintenance difficult because maintenance man's technical merit is uneven.
Summary of the invention
The purpose of the utility model is to solve the problems referred to above that exist in the existing technology, provides a kind of simple in structure, sealing effect better, processing easily, and the transmission shaft of the gearing that be convenient to keep in repair, cost is low is used end cover.
For realizing above-mentioned purpose, the technical solution of the utility model is: a kind of transmission shaft of gearing is used end cover, and it is to be constituted by end cap, plug screw, positioning ring, circlip for hole, rotary shaft lip seal and convex shoulder; Be provided with a convex shoulder with the end cap one in the bottom of rotary shaft lip seal, convex shoulder outside dimension and be 0.4～0.5mm by the gap between the seal shaft; On the circumferential position of end cap, be provided with a tapped hole, plug screw is installed in the tapped hole, is used for grease up; Between rotary shaft lip seal, be provided with a positioning ring, an endless-oil groove is arranged in positioning ring; Circlip for hole is installed in end cap.
The length and width ratio of above-mentioned said convex shoulder is 2: 1.
The utility model structurally is provided with convex shoulder and other parts, has improved the sealability of end cap, has improved the effective utilization of end cap.The utility model is simple in structure, is prone to processing, be convenient to field maintenance, and cost is low.
Description of drawings
Fig. 1 is the sectional view of the utility model;
In the drawings, 1. end cap, 2. plug screw, 3. tapped hole, 4. positioning ring, 5. circlip for hole, 6. rotary shaft lip seal, 7. endless-oil groove, 8. convex shoulder, 9. input running shaft.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated:
Visible by Fig. 1, the present embodiment end cover is constituted by end cap 1, plug screw 2, positioning ring 4, circlip for hole 5, rotary shaft lip seal 6 and convex shoulder 8.Be provided with a convex shoulder 8 with the end cap one in the bottom of rotary shaft lip seal 6, the Aspect Ratio of convex shoulder 8 is 2: 1, its outside dimension and be 0.4～0.5mm by the gap between the seal shaft.On the circumferential position of end cap, be provided with a tapped hole 3, plug screw 2 is installed in the tapped hole 3, is convenient to grease up.In rotary shaft lip seal 6, be provided with a positioning ring 4, an endless-oil groove 7 is arranged in positioning ring 4, after lubricating grease gets into, can avoid the lip-type packing friction overheated.In end cap 1, circlip for hole is installed, can prevents that lip-type packing from deviating from long-term using process.
Novel seal end cap with LF-92III type speed reducer input shaft assembly is an example, and end cap adopts the grey cast iron material, and maximum outside diameter is of a size of φ 300mm, the long 82mm of being; The plug screw specification is M10 * 1 (JN/ZQ4450-86); Tapped hole M10 * 1, circlip for hole φ 110 (GB/T893.1-1986), rotary shaft lip seal φ 85 * φ 110 * 12FB type (GB/T9877.1-1988); Positioning ring FJQ1-300S-02 is with the use that matches of the input shaft of size φ 85.
Claims (2)
1. the transmission shaft of a gearing is used end cover, it is characterized in that: it is to be constituted by end cap, plug screw, positioning ring, circlip for hole, rotary shaft lip seal and convex shoulder; Be provided with a convex shoulder with the end cap one in the bottom of rotary shaft lip seal, convex shoulder outside dimension and be 0.4～0.5mm by the gap between the seal shaft; On the circumferential position of end cap, be provided with a tapped hole, plug screw is installed in the tapped hole; Between rotary shaft lip seal, be provided with a positioning ring, an endless-oil groove is arranged in positioning ring; Circlip for hole is installed in end cap.
