Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a phase-adjusting timing pulley. Background Art

[0002] At present, with the upgrading of automobile exhaust emission standards, the emission requirements for fuel vehicles are getting higher and higher. Electronic fuel injection vehicles have completely replaced traditional carburetor vehicles. The timing signal electronic fuel injection system is the most favored and most commonly used control system by the main engine manufacturers because of its precise control of the fuel injection amount. The phase adjustment timing pulley is an important part of the engine valve system. It is connected to the crankshaft and cooperates with a certain transmission ratio to ensure the accuracy of the intake and exhaust time.

[0003] A Chinese patent publication (publication number: CN216242146U) discloses a timing crankshaft damping pulley for an automobile engine, which comprises: an inner sleeve structure, a slot and a belt; the inner sleeve structure is arranged in the middle of the pulley body, a core layer is arranged inside the inner sleeve structure, and an outer protective layer is arranged outside the core layer; the slot is arranged on the outer ring surface of the pulley body; the belt is installed on the slot, the belt and the pulley body are split and connected, a hub is arranged outside the pulley body, and an inner lining layer is arranged on the inner ring wall of the hub, and a gap is arranged between the inner sleeve structure and the inner lining layer, and four groups of connecting blocks are arranged on the upper and lower parts of the inner lining layer, and the upper and lower connecting blocks are fixed on the outer protective layer. The inner and outer structures of the pulley in the utility model are connected conveniently and quickly. At the same time, the pulley is provided with left and right clamping grooves so that the two ends of the belt can be stably clamped to prevent it from falling out, so as to ensure that the operation is more firm and stable and the use is safe and reliable. Although the pulley is provided with left and right clamping grooves so that the two ends of the belt can be stably clamped to prevent it from falling out, when in use, the clamping grooves can only be used for belts that match the specifications of the clamping grooves. If the belt is too narrow, it will affect the stability of the operation. If the belt is too wide, it cannot be used. It is not convenient to adjust and adapt according to the width of the belt, which reduces the practicality. For this reason, a phase-adjustable timing pulley is proposed. Utility Model Content

[0021] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0022] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-4 As shown, the embodiment of the utility model provides a phase-adjusting timing pulley, comprising a main mechanism 1 and an adjusting mechanism 2;

[0024] The adjusting mechanism 2 is installed on one side of the main mechanism 1, and the main mechanism 1 also includes a gear 11. The outer wall of the gear 11 is slidably connected with an inner gear ring plate 22, and one side of the inner gear ring plate 22 is fixedly connected with a sleeve 23. Four through holes 24 are symmetrically opened on one side of the gear 11, and one end of the sleeve 23 is symmetrically fixedly connected with four connecting plates 25. One side of the four connecting plates 25 is fixedly connected with a threaded rod 26, and the four threaded rods 26 respectively penetrate the four through holes 24. The outer wall of the threaded rod 26 is located on both sides of the gear 11 and is threadedly connected with nuts 27.

[0025] In one embodiment, a baffle 21 is fixedly connected to one side of the gear 11 ; the baffle 21 is provided to block the position of the belt on the gear 11 , thereby preventing the belt from falling off the gear 11 .

[0026] In one embodiment, a mounting hole 12 is provided at a middle position on one side of the gear 11 ; the mounting hole 12 facilitates the installation and fixation of the gear 11 .

[0027] In one embodiment, a key slot 13 is provided on one side of the gear 11, and the mounting hole 12 is connected to the key slot 13; through the setting of the key slot 13, when the gear 11 is fixed, the key slot 13 plays a role of positioning and limiting to prevent the gear 11 from shifting.

[0028] In one embodiment, four sunken grooves 14 are symmetrically formed on one side of the gear 11 ; the anti-fatigue strength is improved by providing the sunken grooves 14 .

[0029] In one embodiment, four weight-reducing holes 15 are symmetrically opened on one side of the gear 11; by providing the weight-reducing holes 15, the weight of the gear 11 can be reduced, making the transmission more stable.

[0030] When the utility model is working: first, the gear 11 is fixed to the use position through the mounting hole 12. When the gear 11 is fixed, the keyway 13 plays a role of positioning and limiting to prevent the gear 11 from shifting. The belt is wound around the gear 11, and one side of the belt is close to the baffle 21. The position of the inner gear ring plate 22 is adjusted according to the width of the belt, so that the inner gear ring plate 22 is close to the belt, and the inner gear ring plate 22 slides on the gear 11. After adjusting the position, the nuts 27 on both sides of the gear 11 are screwed on the threaded rod 26, so that the nuts 27 on both sides clamp the gear 11 and fix the position of the threaded rod 26, thereby fixing the position of the sleeve 23 connected to the threaded rod 26 through the connecting plate 25, and fixing the position of the inner gear ring plate 22. The position of the inner gear ring plate 22 is adjusted according to the width of the belt to adapt to belts of different widths.

[0031] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
